Parosteal lipoma associated with an underlying osteochondroma arising from the hallux

Abstract

Parosteal lipomas are rare benign tumours of mature adipose tissue that arise in continuity with the underlying bone. These lesions represent less than 0.3% of all lipomas and commonly arise in the femur, tibia, humerus and radius. There have been no reported cases of such lesions arising in the foot. Hence, we report the first case of a parosteal lipoma arising in the great toe in association with an underlying osteochondroma.
