Mucoepidermoid carcinoma of Stensen's duct: a case report and review of the literature

Abstract

Background: Mucoepidermoid carcinoma of Stensen's duct is a rare neoplasm, with only five cases reported in the literature.

Methods: We report another case of mucoepidermoid carcinoma of Stensen's duct and review the literature.

Results: Stensen's duct neoplasms tend to be symptomatic at an early stage by causing an obstruction of the parotid duct. New imaging techniques such as MR sialography and sialoendoscopy are very helpful in diagnosis and patient management.

Conclusions: Although the rarity of this condition prevents definitive conclusions about the optimal treatment, we propose that Stensen's duct neoplasms should be treated like similar neoplasms occurring in the parotid gland tissue, taking into consideration clinical stage, tumor grade, and surgical margins.
