Giant Cell Tumor of Metacarpal

巨大細胞瘤在年輕人很常見，特別是三十歲左右，其好發的位置是徑骨遠端和膝關節周邊，但是發生在手指骨上卻是非常罕見的。我們報告一位50歲的婦女，她發現左手上有一腫瘤，半年內愈長愈大，其常規X光片顯示第三手指骨上有一強烈擴張性腫瘤於骨幹上。以病患年齡和病灶位置，不能排除巨大細胞瘤的可能性。雖然手指骨巨大細胞瘤並不常見，但是熟悉其放射線學診斷資訊，對診斷和治療極為重要。

Giant cell tumors of bone are common in young adults with a peak incidence of 30 years of age. The common sites are the distal ends of the radii and knee joints. However, giant cell tumors of the hand bones are rare. Awareness of the lesion is important for correct diagnosis and treatment. A 50-year-old woman presented with a 6-month history of progressive enlargement of a mass on her left hand. Radiographs showed a markedly expansile bone lesion in the diaphyseal region of the third metacarpal. Patient age and location of the tumor cannot be used exclusively to rule out giant cell tumor. Although giant cell tumors of the bones of the hand are rare, awareness of its typical radiographic appearance are important for correct diagnosis and treatment. For patients with an obviously expansile bone lesion in metacarpals, giant cell tumor should be included in the differential diagnoses.
