Angioleiomyoma of parotid gland: a rare case report

Abstract

Angioleiomyoma or vascular leiomyoma first described by Virchow is a very uncommon benign soft tissue tumor. Angioleiomyoma has been defined as frequently painful, benign subcutaneous or deep dermal tumor composed of mature smooth muscle bundles which are surrounded and interlaced by vascular channels. Only 8.5% cases arise in the head and neck. A 39 years old male presented with swelling right side face and upper neck past five years. The swelling was non tender, immobile and non-compressible. There was lateral pharyngeal wall bulge which was pushing the tonsil medially. The patient underwent total conservative parotidectomy and histopathology (HPE) came out to be angioleiomyoma. Angioleiomyoma is difficult to diagnose correctly from clinical manifestations and imaging alone, and a biopsy is mandatory to make the diagnosis.
