Myoepithelioma is a rare benign neoplasm of major and minor salivary glands, composed almost exclusively of sheets, islands or cords of cells with myoepitheliomal differentiation. Myoepithelioma represents 1.5% of all salivary glands neoplasm, most commonly occurs in parotid gland. Here, we report a rare case of myoepithelioma of hard palate.

alivary gland carcinosarcoma is an exceedingly rare and ggressive neoplasm composed of a mixture of carcinomaous and sarcomatous components, with either component apable of metastasis. Salivary gland carcinosarcoma can rise in pleomorphic adenoma (PA) or de novo.1 The present study reports a case of the parotid gland de ovo carcinosarcoma, which contained salivary duct adenoarcinoma and sarcoma...

This paper reports a rare case of sebaceous adenoma on the right mandibular retromolar mucosa in a 73-year-old Japanese man, with a review of the English literature of sebaceous adenomas of salivary gland origin. A painless and yellowish polypoid lesion in the retromolar mucosa was histologically a relatively well-circumscribed neoplastic mass composed of well-differentiated sebaceous cells wit...

composed of cells that exhibit sebaceous differentiation; these tumors account for less than 0.1% of all salivary gland neoplasms (1, 2). The parotid gland is the most frequently involved of the salivary glands, where sebaceous differentiation is common (3). There is little information available in English literature on the radiologic features of this rare neoplasm, especially that of cystic se...

Salivary gland tumours represent approximately 3% of all head and neck tumours. Warthin’s tumour, also known as Papillary cystadenoma lymphomatosum (PCL), is the second most frequent benign salivary gland neoplasm usually found in the superficial lobe of the parotid and is strongly associated with smokers. Here, we report a classical case of Warthin’s tumour of ten years duration in a 52year-ol...

Introduction: Salivary gland tumors (SGTs) are important parts of human neoplasms. The most common SGT is pleomorphic adenoma and the most common malignant SGTs are mucoepidermoid carcinoma and adenoid cystic carcinoma (ACC). Metastasis-associated genes 1 (MTA1), a member of the nucleosome remodeling and histone deacetylation complex, is one newly discovered gene which recruits histone deacetyl...

mucoepidermoid carcinoma is a neoplasm of salivary gland origin, and its laryngeal occurrence is extremely rare. this malignant tumor is composed of two distinct cell types, the epidermoid and mucus cells. prognosis is largely dependent on the histologic pattern. in this report, an extremely rare laryngeal cancer and its clinicopathologic features are described.

Pleomorphic adenoma also known as “mixed tumor” is the most common neoplasm in major salivary glands. It is a benign tumor arises from the parotid gland in 84% of cases and represents 45% of parotid gland tumors [1]. Only 6.5% are found in the minor salivary glands [2]. Salivary gland tumors occurring in ectopic sites are rare and poorly understood; sometime we can find heterotopic tissue arisi...

Acinic cell adenocarcinoma (ACC) is a low-grade malignant salivary neoplasm that constitutes approximately 17% of all primary salivary gland malignancies. In the head and neck region, the parotid gland is the predominant site of origin and ACC is usually more frequent in women than men. Previous radiation exposure and familial predisposition are some of the risk factors for ACC. ACCs rarely inv...

BACKGROUND Fine needle aspiration cytology (FNAC) has been widely accepted as a safe method for diagnosis of salivary gland lesions and its accuracy is increased with increasing the experience of the physician. This study was conducted to examine the sensitivity, specificity and accuracy of FNAC of salivary gland lesions by cyto-histological correlation and to identify the discrepancies that co...
