Abstract
Sebaceous differentiation in parotid glands is a frequent histo-pathological finding (approximately 20-40%), however sebaceous neoplasms occurring in parotid glands are very uncommon. Sebaceous adenomas are benign adnexal neoplasms and account for 0.1% of all salivary gland neoplasms. These adenomas occur most commonly in the parotid gland; however they have been reported in the submandibular, sublingual, and minor salivary glands. The literature describes a few cases diagnosed by fine needle aspirate cytology, however it remains a histological diagnosis in the majority of cases. Histologically, the neoplasm is characterised by abundant islands of sebaceous cells admixed in a fibrous stroma surrounded by cystic and duct like structures. There have been no reports of recurrence following adequate surgical excision. We present a case of sebaceous adenoma in a parotid gland, to draw attention to this differential diagnosis in the diagnosis of parotid masses.
