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.
手指纤维骨性肿瘤是一种罕见的良性疾病，局部切除后预后良好。与骨化性肌炎一样，其临床和组织学特征可能类似恶性肿瘤，尤其是骨外骨肉瘤。正确解读临床、放射学和组织学数据是避免误诊和不必要的根治性手术（如截肢）的前提条件。我们报告一例15岁男孩的病例，他因左拇指出现生长缓慢的肿块就诊，经显微镜检查发现是纤维骨性肿瘤。进行了完整切除，未造成功能丧失。术后15个月，无局部复发。
