OBJECTIVE: To evaluate the value of color doppler ultrasound technique in diagnosing the lumps of salivary gland. METHODS: 233 cases of salivary gland lumps were examined with color doppler high frequency ultrusound technique. Among them were, 189 cases benign and the others malignant. RESULTS: Color doppler ultrasound technique could not only show the morphology, structure, sizc, location and adjoining relationship, but also indicate the pathological classification according to the blood supply. The total coincident rate of this ultrasound diagnosis to the pathological one was 89.3%. CONCLUSION: Color doppler ultrasound technique is a simple and harmless diagnosing method and could preoperatively give a reliable information to the decision of surgical plan.

BACKGROUND: Lipoblastomas are rare tumors of embryonal fat that occur in infants and children. They are usually located in the extremities and trunk. Two cases in the parotid region have been described. A diagnosis on fine needle aspiration (FNA) specimens has been reported in six cases. CASE: Lipoblastoma of the parotid region occurred in a 6-year-old boy and was diagnosed by FNA. Cytology showed rare lipoblasts and hibernomalike cells in a myxoid background with spindle and stellate mesenchymal cells, mature adipose cells and plexiform capillaries. A 7.0-cm, well-circumscribed mass with lobulated adipose tissue and delicate fibrous bands was resected. Microscopically, it showed a lobulated myxoid stroma, many capillaries, mesenchymal cells, lipoblasts and mature adipose cells. CONCLUSION: Lipoblastoma has to be differentiated from myxoid and lipomatous soft tissue tumors, especially from myxoid liposarcoma, a malignancy that classically affects older individuals and shows pleomorphism, atypical lipoblasts and chromosome-12 translocation. A lipoblastoma diagnosis must be established only after careful consideration of all available clinical, radiologic, cytogenetic and morphologic data.

Hyalinizing clear cell carcinoma is a low-grade neoplasm of the minor salivary gland composed exclusively of epithelial cells and not myoepithelial cells. It predominantly affects the oral cavity of adult females. It is microscopically characterized by hyalinizing stroma and clear cells, which are typically positive for cytokeratin markers and negative for S 100 and smooth muscle actin (SMA). Cystic degeneration can also be present. Pathologists should be aware of this new entity so as not to misdiagnose otherwise. To our knowledge, this is the first case report of its kind from Malaysia.

TI - [Strategy of neck dissection in parotid cancer]
SO - Nippon Jibiinkoka Gakkai Kaiho 2002 Feb;105(2):178-87
AD - Division of Head and Neck, Cancer Institute Hospital, Tokyo.
We conducted definitive surgery on 45 patients with untreated primary parotid cancer from 1975 to 1995, and evaluated methods of neck dissection and results of treatment. All 14 with clinical neck lymph node metastasis underwent ipsilateral radical neck dissection and only 1 developed neck lymph node recurrence at the peripheral dissected site. Of 31 patients without clinical neck lymph node metastasis, 27 of 19 of 36 with high-grade malignancy and 12 of 24 with T3 or T4 did not undergo prophylactic neck dissection and developed latent neck lymph node metastasis in 2 cases (7.4%). Whereas in most cases we achieved good control of the primary site but neck lymph node recurrences occurred, recurrent sites were observed all around the ipsilateral neck and prognosis were very poor if neck dissection was conducted as secondary treatment. Although histopathological diagnosis was considered feasible for predicting occult neck lymph node metastasis, correct diagnostic with fine needle aspiration cytology revealed only 21.8%. Pathological positive lymph nodes in 15 patients who underwent neck dissection were detected all over (level I to V) the ipsilateral neck and the recurrent positive rate at level II was 100%. Based on the above results, we conclude that (1) in cases with neck lymph node metastasis in preoperative evaluation, ipsilateral radical neck dissection is mandated, and (2) in cases without neck lymph node metastasis, prophylactic neck dissection is not usually needed. When pathological results of frozen section from intraoperative jugulodigastric nodal sampling are positive, ipsilateral radical neck dissection is mandated.

Laryngeal manifestations of malignant sialogenic neoplasias are rare. This paper documents the clinical features, treatment, biological behaviour and prognosis of 15 cases of malignant sialogenic tumours of the larynx that were reviewed in a retrospective clinical and histopathological study. The 15 cases of malignant sialogenic tumours of the larynx were diagnosed at the University Hospital, Eppendorf, over a period of 33 years (1965-1998). Forty per cent were adenoid cystic carcinomas, 33 per cent mucoepidermoid carcinomas and 27 per cent were poorly differentiated adenocarcinomas. Local tumour resection, if necessary in combination with bilateral neck dissection and post-operative radiotherapy, was associated with a five-year survival rate in 80 per cent of the mucoepidermoid carcinoma cases. Adenoid cystic carcinoma was associated with a less favourable five-year survival rate of 33 per cent. Low-differentiated adenocarcinomas were associated with the least favourable prognosis with a five-year survival rate (25 per cent). The prognosis for these tumours is thus poorer than for squamous cell carcinomas with the same localization and TNM status.

TI - Pleomorphic adenoma of the parotid gland with extensive bone formation.
SO - Pathol Int 2001 Nov;51(11):883-6
AD - First Department of Pathology, Hiroshima University Faculty of Medicine, Japan.
We report an unusual case of pleomorphic adenoma with extensive bone formation, occurring in the parotid gland of a 58-year-old Japanese man. The tumor was a well-circumscribed mass that measured 20 x 20 x 15 mm and contained extensive bone formation. Histologically, most of the tumor was composed of bone and chondroid tissues. The bone formation with a marrow-like structure occupied half the volume of the tumor. The chondroid tissues merged continuously into bone tissues. The bone tissue seemed to be formed within areas of chondral tissue by a process of enchondral ossification. Except for the unusual amount of large bone formation, the tumor showed histology of pleomorphic adenoma, particularly at the periphery of the tumor. These histological findings suggest the possibility of extensive enchondral ossification in pleomorphic adenoma.

AD - Division of Head & Neck/Plastic & Reconstructive Surgery, Department of Surgery, Queen Mary Hospital, University of Hong Kong Medical Center, Pokfulam, Hong Kong, China. email@example.com
BACKGROUND: Efficacy of frozen sections was assessed in terms of its various applications. The changing role of frozen sections in parotid surgery was examined. METHOD: Records of parotid operations over a 15-year period in a University Department of Head & Neck Surgery were reviewed. RESULTS: Of 241 operations, frozen sections were performed on 32. Applications of frozen sections included diagnosis, margin clearance, and checking suspicious lymph nodes and nerve invasion. The false-positive rate for malignancy was 12.5%. Margins may still be involved despite correct tissue diagnosis from sampling error. No inappropriate surgery resulted from the information obtained. With the advent of fine-needle aspiration, frozen sections were less often called for and a shift from a diagnostic role to margin checking was seen. Frozen sections picked up all unsuspected malignant tumors. CONCLUSION: Frozen sections are helpful when interpreted cautiously, but clinical assessment and fine-needle aspiration are also important components in the workup.

BACKGROUND: Ipsilateral salivary gland tumors of different histologic types are rare and make up less than 0.3% of all salivary gland neoplasms. Only nine cases of synchronous benign and malignant ipsilateral parotid gland tumors have been described in the literature. METHODS: Two additional cases of synchronous benign and malignant neoplasms in the parotid gland are reported and discussed with a review of literature. RESULTS: Our first case describes a pleomorphic adenoma and a salivary duct carcinoma, an entity not previously reported in the literature. The second case documents the most common benign and malignant ipsilateral parotid gland neoplasm reported in this case series, a Warthin's tumor and a mucoepidermoid carcinoma. CONCLUSIONS: Synchronous salivary gland tumors exhibiting both benign and malignant components are uncommonly observed, with only nine cases published to date. We describe two additional cases of a synchronous benign and malignant ipsilateral parotid gland tumor. Copyright 2002 Wiley Periodicals, Inc.

TI - Secretory carcinoma of the breast: a tumour analogous to salivary gland acinic cell carcinoma?
SO - Histopathology 2002 Mar;40(3):223-9
AD - Department of Pathology, University of Tokushima School of Medicine, Tokushima, Japan. email@example.com
AIMS: Acinic cell-like breast carcinoma is a newly recognized entity, and few acinic cell-like breast carcinoma cases have been reported. All reported acinic cell-like breast carcinomas were counterparts of the solid type of acinic cell carcinoma of the salivary gland. We report here three cases of secretory breast carcinoma with acinic cell differentiation, and discuss the similarity between secretory breast carcinoma and acinic cell carcinoma of the salivary gland. METHODS AND RESULTS: The cases were histologically identical to acinic cell carcinoma of the salivary gland: papillary-cystic type in case 1, a mixture of papillary-cystic, microcystic and follicular type in case 2, and microfollicular type in case 3. Immunohistochemically, the tumour cells were positive for salivary-type amylase, lysozyme, S100 protein and alpha 1-antitrypsin, and negative or less reactive for gross cystic disease fluid protein-15 and oestrogen receptor. All three cases did not reveal metastasis or recurrence. CONCLUSIONS: These cases were typical of secretory breast carcinoma, and were clinically, histologically and immunohistochemically analogous to acinic cell carcinoma of the salivary gland. We emphasize that secretory breast carcinoma and acinic cell carcinoma of the salivary gland may be identical lesions.

SO - Acta Otolaryngol 2001 Jul;121(5):647-51
AD - Department of ENT, University of Hamburg, Germany. email@example.com
The aim of this study was to examine the clinical presentation of patients with malignant lymphoma of the major salivary glands. In a retrospective study, 26 patients with a non-Hodgkin lymphoma (NHL) of the major salivary glands were examined. The results showed a distinct preference for the female gender. Two groups with clinical differences were observed depending on lymphoma manifestation as either extranodal-parenchymal (extranodal) or with intra- or periglandular (nodal) lymph node disease. Differences between these two groups existed with regard to the length of clinical history, recurrent vs continuously progressing symptoms and presentation on ultrasound examination (multiple masses compared to solitary masses). Patients with an extranodal lymphoma always showed disease limited to the affected gland, whereas those patients with a nodal lymphoma presented with stage II or higher (Ann Arbor Classification). In these patients, local recurrence was also five times higher (5/13; 38.4%) than in patients with an extranodal lymphoma (1/13; 7.7%). In 1 patient (7.7%) with extranodal lymphoma, dissemination was observed, compared to 6/13 patients (46.2%) in the group with nodal disease. Seven out of 13 patients (53.8%) with nodal disease died due to lymphoma spread and 1/13 (7.7%) of the patients with extranodal disease. There seem to be distinct clinical differences in the course of patients with NHL of the major salivary glands, depending on extranodal or nodal disease presentation. The histopathological diagnosis, with special recognition of the particular lymphoma pathogenesis, constitutes an important prognostic factor in these patients.

Malignant myoepitheliomas of the salivary gland are very rare tumors which may either arise de novo or develop in a pre-existing pleomorphic adenoma. We report a case of malignant myoepithelioma of the minor salivary gland that progressed from benign pleomorphic adenoma. The original pleomorphic adenoma was resected in 1979 (the '79 tumor). The first recurrent tumor was operated in 1995 (the '95 tumor). The '95 tumor was diagnosed as pleomorphic adenoma. Although the myoepithelial tumor component was more prevalent in the '95 tumor, histological features of the first recurrent tumor were similar to the '79 tumor. The second recurrent tumor showed more aggressive clinical features (the '98 tumor). It also showed massive growth of myoepithelial tumor cells with bone invasion, which led to the diagnosis of the '98 tumor as malignant myoepithelioma. With adequate surgical margin, the patient has been free from tumor recurrence for 20 months.

We describe three cases of sclerosing polycystic adenosis (SPA) of the parotid gland, a salivary condition analogous to fibrocystic disease of the breast. For the first time, immunoreactivity for oestrogen and progesterone receptors was demonstrated, suggesting a possible participation of hormone stimulation in its pathogenesis. In addition, all our cases showed foci of dysplasia of the ductal epithelium, which in one case was severe enough to amount to carcinoma in situ. This feature that has not previously been reported in SPA.

SO - Virchows Arch 2002 Jan;440(1):77-84
AD - Institute of Clinical Pathology, Department of Pathology, University of Zurich, Switzerland.
The prognosis of salivary gland adenoid cystic carcinoma (ACC) depends on the clinical stage, the location of the primary tumor, and the histologic growth pattern. ACCs with a cribriform growth pattern have a better prognosis than those with a solid growth pattern; however, clear-cut grading criteria have not yet been established, and therefore prognostic indicators on a molecular level are of special interest. In order to analyze tumor tissue with different growth patterns, cribriform and solid tumor areas of 25 patients were microdissected and separately analyzed for loss of heterozygosity (LOH) at nine polymorphic microsatellite markers located between 6q14 and 6q27. LOH was detected in 19/25 (76%) patients and LOH rates were highest at markers D6S441, D6S310, D6S311 and UTRN, which are located at 6q23-25. Combined analysis of LOH at these four markers shows that in primary tumor subtype foci with cribriform growth pattern LOH is associated with high TNM stages (P<0.01), high T stages (P=0.01), positive lymph node status (P=0.03), an unfavorable disease course (P=0.02), and the presence of >10% solid growth pattern (P=0.05). In contrast, in primary tumor subtype foci with solid growth pattern, no significant differences in LOH rates were found in patients from prognostically and histologically favorable versus unfavorable patient groups. The frequent occurrence of LOH at 6q23-25 and the correlation of LOH rates with prognostic parameters indicate that a prognostically important tumor suppressor gene is located in this chromosomal area.

TI - Telomerase components as a diagnostic tool in human oral lesions.
SO - Int J Cancer 1999 Jan 5;80(1):1-4
AD - Department of Oral Surgery, Ehime University School of Medicine, Onsen-gun, Japan.
Telomerase activity is considered to be a diagnostic marker of malignancy since most malignant cells express this activity and most somatic cells do not. However, the detection of telomerase activity is rather complicated and is affected by many factors. Recently, human telomerase components were cloned and found to consist of 3 subunits. We assessed which component of telomerase best correlates with malignancy in order to study the possibilities for developing a new diagnostic marker. Telomerase activity was measured by a telomeric repeat amplification protocol (TRAP) assay, and the telomerase components hTR, hTRT-mRNA and TP1-mRNA were detected by the reverse transcriptase-polymerase chain reaction (RT-PCR). Twenty-five of 26 oral malignant lesions, 9 of 22 benign lesions and none of 19 normal control tissues exhibited distinct telomerase activity. hTR and TP1-mRNA expression levels were detected in all malignant lesions and normal control tissues and had no significant correlation with the telomerase activity results. In contrast, hTRT-mRNA expression was closely associated with telomerase activity. All lesions expressing hTRT were telomerase positive. In addition, some samples of dysplastic lesions, benign tumors, lichen planus and normal mucosa exhibiting poor telomerase activity revealed weak expression of hTRT. Expression levels of hTRT-mRNA positively correlated with clinical and pathological findings. Detection of hTRT-mRNA by RT-PCR appeared to be more sensitive for telomerase than measurement of telomerase activity by the TRAP assay. Detection of hTRT-mRNA may provide information useful in the diagnosis of oral malignancies.

TI - 5-Fluorouracil suppression of NF-KappaB is mediated by the inhibition of IKappab kinase activity in human salivary gland cancer cells.
SO - Biochem Biophys Res Commun 2001 Mar 23;282(1):292-6
AD - Second Department of Oral and Maxillofacial Surgery, Tokushima University School of Dentistry, Tokushima, Japan. firstname.lastname@example.org
We have recently shown that 5-Fluorouracil (5-FU) suppresses the transcription factor NF-kappaB in human salivary gland cancer cells (cl-1) by mediating upregulation of IkappaB-alpha expression. However, the precise mechanism involved in this action has not yet been elucidated. IkappaB kinases (IKK-alpha and IKK-beta) are the key components of the IKK complex that mediates activation of NF-kappaB in response to external stimuli such as cytokines. In addition, NF-kappaB-inducing kinase (NIK) and mitogen-activated protein kinase kinase kinase 1 (MEKK-1), both of which are the upstream kinases for the IKKs, interact with and activate the IKKs. Thus, we investigated the molecular mechanisms involved in the suppression of NF-kappaB by 5-FU. Although 5-FU did not affect the expression levels of IKKs, NIK, or MEKK-1, IKK activity in cl-1 cells was suppressed at both 6 h and 12 h after treatment with 2 microgram/ml 5-FU. Moreover, when cells were treated with various concentrations of 5-FU for 12 h, the concentration of 2 microgram/ml efficiently inhibited the IKK activity as compared to 1, 5, or 10 microgram/ml. The expression of Fas-associated death domain-like interleukin 1-converting enzyme-inhibitory protein (FLIP), which acts as an inhibitor of an initiator caspase (caspase-8), was down-regulated by 5-FU treatment in cl-1 cells. Apoptosis, as evidenced by cleavage of poly(ADP-ribose) polymerase through the action of an executioner caspase (caspase-3), was also clearly observed. Thus, these results suggest that 5-FU induction of apoptosis in cl-1 cells may be mediated by suppression of NF-kappaB via inhibition of IKK activity. Copyright 2001 Academic Press.

An analysis of all parotidectomies performed for neoplastic lesions in the maxillofacial unit at a district general hospital during a 26-year period between 1974-1999 was undertaken. The details analysed were age, sex, histology and temporal variations in the frequency of specific tumour types during the study period. A total of 538 parotidectomies performed on 529 patients in whom 560 tumours were present, formed the basis of this study. Marked variations were present in the age and sex distribution and relative frequency of specific tumour types in this study, when compared to previous reports. There were also differences in the age and sex distribution of pleomorphic adenoma and adenolymphoma (P <0.0001) in this study. The relative frequency of benign tumours and adenolymphoma increased, whereas that of pleomorphic adenoma decreased during the study period. In addition, there was a statistically significant decrease in the relative frequency of pleomorphic adenoma (P <0.0001) and an increase in adenolymphoma (P <0.0001) when comparisons were made with previous studies. This study from a defined population may be more representative of the true proportion of specific tumours in this population. The potential implications of the results on the investigation and treatment of parotid neoplasms is highlighted.

This is a study of 33 (32 patients) confirmed Warthin's tumours (adenolymphomas) treated surgically at Bristol Royal Infirmary (1985--1995) focussing specifically upon 17 salient histopathological features together with capsular measurement by micrometry. Twenty-four out of 33 tumours had 'thin' capsules (< or = 200 microm), whereas 5/9 'thick' capsules were associated with gross tumour degeneration. The degenerative features including cystic change, squamous metaplasia, corpora amylacea like bodies, etc. were quantified. Tumours were classified into subtypes (typical, stroma poor, etc). These variations were not associated with age or sex. In 20/33 tumours a marginal sinus suggested a lymph node origin. Fine needle aspiration cytology (FNA) smears showing degeneration features are a diagnostic problem, but histopathological features are reflected in such smears and their recognition enhances diagnostic precision, enabling controlled surgical enucleation, the ideal operation, to be performed in most cases. In this study only 12 tumours were so treated; 11 others received parotidectomy. The theories of histogenesis are reviewed and discussed.

We examined the immunohistochemical localization of cyclooxygenase (COX)-2 in human salivary gland tumors. Thirty salivary gland adenomas (SGA), 40 salivary gland carcinomas (SGC) and 15 normal salivary glands (NSG) were studied. NSG showed restricted COX-2 staining only in the epithelial cells of salivary ducts. In contrast, COX-2 protein was detected in 27 cases of SGA (90%), except for three myoepitheliomas, and in all cases of SGC (100%) at various intensities and in various fashions. Thirteen SGA (43%) and 36 SGC (90%) cases showed strong COX-2 staining predominantly in tumor cells containing ductal components, as did serous and mucous acinic components of acinic cell carcinomas, mucoepidermoid carcinomas and mucinous carcinomas. These findings may suggest that COX-2 in salivary gland tumors is expressed in tumor cells derived from pluripotential ductal epithelium that can histologically develop into either serous or mucinous acinar cells.

We report two patients with Warthin's tumor who were also infected with Mycobacterium tuberculosis. Case 1 was a 75-year-old woman with Warthin's tumor and multiple small epithelioid granulomas with caseous necrosis involving the submandibular gland. This patient died of tuberculous meningitis 4 months after biopsy. Case 2 was a 78-year-old man with a 10-year history of a parotid mass which had enlarged rapidly over 2 months. Surgical excision revealed Warthin's tumor and epithelioid granulomas involving the left parotid gland. DNA extracted from paraffin sections was amplified by nested polymerase chain reaction (PCR) with primer sets for the mycobacterial 65-KDa antigen gene. Restriction enzyme digestion of the PCR products could differentiate Mycobacterium tuberculosis from other mycobacteria in both cases. Although the histogenesis of lymphoid components of Warthin's tumor is controversial, the frequent prevalence of inflammation or necrosis and our present findings suggest these components have a similar behavior to regional lymph nodes.

OBJECTIVE: To test the effects of arginine-aspartate (RD) on metastasis of salivary cystic carcinoma (SACC). METHODS: Highly metastatic SACC cell line SACC-LM was used in the study. The effect of RD on tumor cell-ECM adhesion was assayed by MTT technique. The effect of RD on invasion and migration of SACC-LM were evaluated using modified boyden chamber. RESULTS: RD inhibited tumor cell fibronectin adhesion at 5 mg/L concentration, but no effects on tumor cell laminin and tumor cell type IV collagen adhesion. RD inhibited the invasion at 1, 5, 25 mg/L, and inhibited the migration only at 25 mg/L. CONCLUSIONS: The result shows that the RD has an antimetastatic effect on SACC-LM cells in vitro.

Sjogren's syndrome (SS) represents a pathological model of the evolution from polyclonal B lymphocyte activation to oligoclonal/monoclonal B cell expansion, which may culminate in the development of a malignant lymphoproliferative disease. The different phases of this process are usually marked by the appearance of antigen-driven activated B cell clones, which are commonly IgM-positive and with rheumatoid factor (RF) activity. However, the agent(s) able to trigger B cell proliferation is still unknown. A similar pathogenetic mechanism exist in mixed cryoglobulinemia, another autoimmune disease that often evolves to non-Hodgkin's lymphoma (NHL) and in which hepatitis C virus (HCV) infection has been demonstrated to play an etiopathogenetic role. In the present study, we cloned and sequenced the antigen receptor (IgR) variable region genes of SS-associated monoclonal non-neoplastic lymphoproliferations and compared them with those of our previous reported HCV-associated NHL, to derive clues on the antigen(s) that sustains SS. The results obtained showed remarkable homologies between the antigen combinatory regions of the IgR expressed by both diseases. These homologies concern: a) the specific combinations of heavy and light variable region genes; b) the limited length of complementarity-determining regions (CDR3); c) the homology with antibodies with RF activity; d)the amino acid sequences of CDR3 in which common somatic mutations are present that possibly determine the antigen-binding specificity. In conclusion, although there are significant differences between SS and HCV-associated lymphoproliferative diseases, they share many molecular characteristics, which suggest an immunological cross-reactivity or molecular mimicry among the agents that underlie these disorders.

Solitary fibrous tumours are rare tumours originally described in the pleura. More recently there have been reports of these tumours arising at other sites including the parotid region. They are characterized histologically by a variety of growth patterns that can be confused by the unwary with other benign or malignant tumours particularly sarcomas. We present a case occurring in the pre-auricular region which presented diagnostic difficulties.

One hundred and eight parotidectomies performed by a single consultant were reviewed. Eighty-five patients had primary parotid disease, 23 patients had extra-parotid primaries. Pleomorphic adenoma was the most common histological diagnosis. In patients with primary parotid disease, a post-operative temporary facial nerve palsy was noted in 15 patients, with a further four developing a permanent palsy. Patients with metastatic disease to the parotid had a poor prognosis.

BACKGROUND: Malignant tumors of the salivary gland are rare entities that are treated primarily by surgical resection. For patients with recurrent or unresectable disease, options include radiation therapy or chemotherapy; however, responses are few and of short duration. Patients with metastatic disease have been treated with chemotherapy, but, again, response rates have been low and of short duration. METHODS: A 52-year-old man was seen with a mass on his tongue. A biopsy revealed adenocarcinoma of a minor salivary gland. Ten months after surgical resection, neck dissection, and radiation therapy, the patient was found to have metastatic disease to the lung. Chemotherapy was initiated with carboplatin and paclitaxel. RESULTS: The patient obtained a complete response after six cycles of carboplatin and paclitaxel. CONCLUSIONS: The use of carboplatin and paclitaxel in the setting of metastatic salivary gland cancer is a viable option. Copyright 2002 Wiley Periodicals, Inc.
