A common tumour at an uncommon location: Lesser trochanter osteochondroma

Abstract

Osteochondromas are benign osteocartilaginous tumours, which are developmental abnormalities rather than actual neoplasms. The lesser trochanter is an extremely rare location for a solitary osteochondroma, and depending on the tumour’s size, the patient can exhibit various symptoms, including a limited range of motion. This case study describes a rare instance of a benign solitary osteochondroma of the lesser trochanter identified and managed using an excisional biopsy following Ludloff’s approach. With intraoperative fluoroscopy, we could accurately outline and remove the entire tumour mass without endangering the nearby essential tissues.
