Osteochondromas are common benign bone tumors arising from metaphyseal region of long bones. They are notorious for undergoing malignant transformation. We present a case of a middle aged woman with recurrent episodes of swelling in the middle of left 4th finger post excision. Bone scan was performed to look for any malignant transformation of finger lesion and also to rule out skeletal metastases due to recent onset bone pains. 99m Tc MDP (Technetium methylene diphosphonate) bone scan demonstrated a focal hot spot in middle of left 4th finger along the radial side. There was no evidence of skeletal metastases. Surgery is usually curative (70-90%). Limb sparing wide local excision is treatment of choice.
骨软骨瘤是常见的良性骨肿瘤，起源于长骨的干骺端区域。它们因发生恶性转化而声名狼藉。我们报告一例中年女性病例，在左手中指切除术后出现反复肿胀。进行骨扫描以查找手指病变的任何恶性转化情况，并排除近期出现骨痛所致的骨转移。99m锝亚甲基二膦酸盐（99mTc MDP）骨扫描显示左手中指桡侧中部有一个局灶性热点。没有骨转移的证据。手术通常可治愈（70 - 90%）。保肢广泛局部切除是首选治疗方法。
