Fibro-osseous pseudotumour of the digit--amputation for a benign but aggressive lesion

Abstract

Fibro-osseous pseudotumour is a rare, benign lesion which behaves aggressively and is, therefore, commonly misdiagnosed as a malignancy. Fibro-osseous pseudotumour shares many features with myositis ossificans and many consider it to be a subcutaneous variant of the latter. Early diagnosis and treatment by excision to normal tissue margins is important to preserve function and avoid digital amputation. We report a case of fibro-osseous pseudotumour of the finger which required ray amputation due to rapid progression of the lesion.
