Vascular Leiomyoma overlying the Abductor Hallucis: A case report

Abstract

Vascular Leiomyoma is a benign soft tissue tumor that originates from the tunica media of blood vessels. This rare slow growing tumor requires histopathological examination for accurate diagnosis. As a result, preoperative diagnosis is difficult. We present the case of a 55 year old female referred to our surgical practice with a symptomatic slow growing mass on her right medial arch. Prior to excisional biopsy, ultrasonographic examination showed a 4mm unilocular anechoic avascular cyst within the subdermal layer overlying the abductor hallucis muscle belly. Whilst rare, vascular leiomyomas should be considered as a differential diagnosis for all slow growing foot and ankle masses.
