Mucoepidermoid Carcinoma of Minor Salivary Glands with Clinical Features of a Benign Lesion

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.

Great Role

Mucocele is a benign lesion characterised by an extravasation or retention of mucous secretion in submucosal tissue from minor salivary glands. The occurrence of mucocele is common in the oral cavity, with more than 70% of cases on lower labial mucosa. The occurrence of mucocele on the tongue is considered rare and accounted for only 2.25% in the previous literature. Histopathological examination plays a great role in the confirmation of the clinical diagnosis. Management of mucocele is at times challenging. This paper highlights a rare case of mucocele in a 5-month-old infant who was successfully managed under day-care anaesthesia.

Mucoepidermoid carcinoma is the most common malignant, locally invasive tumour of the salivary glands and accounts for approximately 35% of all malignancies of the major and minor salivary glands. Mucoepidermoid carcinoma that originated from the lacrimal gland is exceedingly rare in teenage patients, with only a few cases reported. Herein, we report clinical and radiological findings of a mucoepidermoid carcinoma arising from the lacrimal gland in a 15-year-old boy. We suggest that since preoperative imaging findings are not diagnostic for mucoepidermoid carcinoma, histopathologic examination should be performed for definitive diagnosis. Complete surgical resection is the treatment of choice for low-grade lacrimal gland mucoepidermoid carcinoma.
