Sebaceous lymphadenoma is an unusual salivary gland neoplasm which is rarely correctly diagnosed pre-operatively in the parotid gland. Two cases of sebaceous lymphadenoma are presented in which, in common with most cases reported in the literature, the correct pre-operative diagnosis was not made. Sebaceous lymphadenoma rarely transforms into a malignant tumour. Fine needle aspiration cytology ...

Adenoid cystic carcinoma (ACC) occurs more commonly in the minor salivary glands of the palate on than the tongue. ACC is a malignant neoplasm that accounts for 1-2% of all head and neck malignancies and 10-15% of all salivary gland malignancies. ACC affects the exocrine glands at any site, but the parotid gland is the most common site in the head and neck region. Many factors should be taken i...

Canalicular adenoma is an uncommon benign salivary gland neoplasm that has a marked predilection for occurrence in the upper lip. It is composed of columnar cells arranged in branching and interconnecting cords of single or double cell thick rows. This tumor has an excellent prognosis after conservative surgical treatment in all locations. In the present report we describe, using immunohistoche...

Chronic sclerosing sialadenitis or Küttner tumor is an unusual chronic inflammatory disease of the salivary gland that mimics a malignant neoplasm clinically because of presentation as a hard mass. The diagnosis can only be made histologically and is an underrecognized entity. Recent studies have shown important features that characterizes the disease mainly as an autoimmune reaction. The aim o...

BACKGROUND The characteristic cytologic features of the common salivary gland lesions have been well-delineated in literature. However, there also exist cytologic pitfalls and overlapping features that make an accurate diagnosis difficult in few cases. The present study was designed to compare the cytologic findings of salivary gland lesions with the histologic diagnoses, in order to assess the...

introduction: in this study the automatic separation of oral and salivary gland activity and spontaneous secretion by means of factor analysis for quantitative salivary gland scintigraphy is introduced. methods: after intravenous administration of 99mtc sodium pertechnetate, dynamic scintigraphy was performed. 20 minutes after tracer application 2 ml of lemon juice was delivered to stimulate t...

Pleomorphic adenoma, also known as mixed tumor, is a benign tumor which typically presents as a painless and persistent mass. The majority of pleomorphic adenomas involve the salivary glands, most commonly the parotid gland. Other sites include breast and skin. It is a rare tumor in the vulva. In this article we are reporting a case of pleomorphic adenoma of labia with characteristic pathologic...

Adenoid cystic carcinoma is a malignant neoplasm arising from the salivary glands. The most striking feature of this tumor is that it is locally aggressive, with perineural invasion, tendency to metastasize, high recurrence rates. The parotid gland is the most commonly affected site in the head and neck region, tongue being relatively rare. The current study presents a rare case of 6 years old ...

Metastasis to the oral cavity is a rare occurrence with renal cell carcinoma (RCC) being the third most common tumor to metastasize to this location. Buccal mucosa is rarely involved and in the absence of a known primary, such lesions pose a diagnostic challenge to the pathologist. The histomorphological features may mimic a primary salivary gland neoplasm adding to the dilemma. We present one ...

Sclerosing mucoepidermoid carcinoma (SMEC) is a distinct but an uncommon salivary gland neoplasm with only 19 cases reported in English literature till date. Densely collagenous sclerotic stroma, resemblance to other benign lesions and rarity of this tumour often makes the diagnosis of SMEC challenging. Here we report a case of SMEC in a 73-year old female patient suffering from filariasis. Cli...
