Pilomatrixoma in the Parotid Region: A Case Report

Abstract

Pilomatrixoma is a benign skin neoplasm of hair matrix origin, commonly seen in the head and neck region. Pre-operative fine-needle aspiration cytological (FNAC) diagnosis helps in the management of the case. It is important to identify the benign neoplasm on FNA smears, as surgical excision is curative. We present a case of 21-year-old male presenting with a swelling below the ear lobe. With the clinical impression of parotid tumor/lipoma, he was referred for FNAC. On aspiration, the scant whitish material was obtained. Smears showed clusters of anucleate squamous cells, small groups of basaloid cells, many multinucleated giant cells and macrophages. Cytological diagnosis of pilomatrixoma was made, which was later confirmed by histopathology.
