Intraparotid Schwannoma Masquerading as Primary Spindle Cell Tumour of Parotid: A Diagnostic Pitfall

Jenna B Bhattacharya et al. J Cytol. 2017 Oct-Dec.

Abstract

A middle-aged female presented with a painless, slowly growing mass in the left parotid region; fine needle aspiration cytology from the mass showed uniform spindle cells in a fibrillary background with some cells showing palisading. A cytodiagnosis of schwannoma was given, which was further confirmed on biopsy.

Keywords: Nerve sheath tumor; parotid neurilemmoma; salivary gland schwanomma.
