Abstract

Background.

Primary malignant tumors involving Stensen's duct are rare neoplasms, with less than 30 cases reported. We report a case of primary squamous cell carcinoma (SCC) involving Stensen's duct in a patient infected with human immunodeficiency virus (HIV) and describe the role of fine-needle aspiration (FNA) and MRI in the diagnosis of this rare entity.

Methods.

A 47-year-old man with HIV presented with intermittent parotid swelling and pain unresponsive to conservative treatment. He subsequently developed a mass emanating from Stensen's duct, and an MRI and ultrasound-guided FNA revealed carcinoma of Stensen's duct. Total parotidectomy with postoperative external beam radiation therapy was performed.

Results.

The patient remains disease free 31 months after treatment.

Conclusions.

Primary SCC of Stensen's duct is a rare entity that may mimic benign obstructive parotid disease. FNA and MRI are useful in the diagnosis and assessment of disease extent. © 2008 Wiley Periodicals, Inc. Head Neck, 2009
