PD.244 Mucoepidermoid carcinoma of minor salivary glands. A clinical study of 16 cases and review of the literature

AbstractPleomorphic adenoma is the commonest benign tumour of the major salivary glands. It can also occur in minor salivary glands, mainly in the oral cavity, but also in other sites in the head and neck both within and outwith the upper aerodigestive tract. We present a rare case of pleomorphic adenoma of the nasal septum with consideration of the clinical management and a review of the literature.

Gland Tumour

The origin of a salivary gland tumour is attributed to cells at various levels of differentiation which present histologically as diverse tissues and cellular patterns. Mitochondria-rich, eosinophilic oncocytes are cells commonly encountered in salivary gland neoplasms. We report a case of mucoepidermoid carcinoma (MEC) in the palate of a 43-year-old female that exhibited a prominent oncocytic component. While the parotid and submandibular glands have been reported as predominant sites for oncocytic MEC (OMEC), the palate and minor salivary glands are rare sites for occurrence. Also, most of the reported cases of OMEC have been histologically of low-grade mucoepidermoid carcinoma with large cystic spaces and good prognosis. In this article, we discuss the differential diagnosis and diagnostic workup of an MEC presenting with oncocytes.

Age Range

This study was conducted to see the incidence of the lesions of Salivary Gland. All the cases of salivary tissues submitted to the Pathology Department of King Edward Medical University were taken at the end of year (Jan 2005-Dec2005) and reanalyzed. There were 42 cases of salivary glands, out of which 19(45%) were males and 23(55%) were females. Age range was 12-72 years. Major number of cases (17) were from parotid, whereas 15 were from submandibular, 04 and 06 were from sublingual and minor salivary glands like palate respectively. There were 25(59.52%) pleomorphic adenoma, 01(2.3%), 01(2.3%), 04(9.5%), 07(16.6%) were monomorphic adenoma, lymphoepithelioma, mucoepidermoid carcinoma, adenoid cystic carcinoma respectively. Only 04(9.5%) cases showed chronic sialadenitis.
