[Fibro-osseous pseudotumor of the thumb. Report of a case].
Fibro-osseous tumor of the digits is an uncommon, benign condition with an excellent prognosis after local excision. Like myositis ossificans, clinical and histological features may mimic a malignant tumour, especially an extraskeletal osteosarcoma. A correct interpretation of clinical, radiological and histological data is a prerequisite to avoid misdiagnosis and unnecessary radical surgery (for example, amputation). We report the case of a 15-year-old boy who presented with a slow-growing mass of the left thumb, which turned out to be a fibro-osseous tumor on microscopic examination. A complete excision was performed without loss of function. Fifteen months postoperatively, there was no local recurrence.
