腫瘤性石灰沉著為造成關節週邊節締組織腫瘤性鈣化的少見疾病。病灶通常在股、肘及肩等關節,位於肩甲骨下區則相對少見。因此報告一有慢性腎衰竭已洗腎十年的個案,其主訴為右背側患有一硬塊,於三年間逐漸成長,胸部X光及電腦斷層可見右肩甲骨下區有大型鈣化腫瘤。手術切除成功證實為腫瘤性石灰沉著且追蹤一年無復發跡象。
Tumoral calcinosis is an uncommon disorder causing single or multiple circumscribed calcified masses in periarticular connective tissue. Lesions are common around hip, elbow and shoulder joints. Right subscapular region is a relative uncommon location for tumoral calcinosis. Here we report a case of chronic renal failure under hemodialysis for 10 years. The patient complained a growing mass at his back for 3 years. Chest plain film and CT were performed and a large calcified mass was found at right subscapular region. Successful surgical resection confirmed the diagnosis of tumoral calcinosis and there was no recurrence during a 1-year follow-up period.
