摘要

我們報告一個罕見的多發性胸壁脂肪肉瘤的病例，這是一位61歲的女性，她在左胸壁鎖骨下的位置觸摸到一個腫瘤，同時感到局部壓痛及左上臂的輻射性疼痛。在理學檢查上，於左前胸可觸模到一個有彈性的、可動的、約5×3公分大小的腫瘤，超音波檢查則顯示此腫瘤的邊緣完整、密度不約。臨床初步診斷為一胸壁脂肪瘤，於是幫病人安排了腫瘤切除手術，術中移除較表淺且較大的腫瘤後，經由手指觸模又發現了另一顆較深的、啞鈴形的腫瘤，這顆較深的腫瘤也於術中一併切除。組織病理上顯示這兩顆腫瘤均為分化良好的硬化型脂肪肉瘤，他們的細胞具有非典型、高染色質的細胞核，偶而可見脂肪母細胞。在術後至今12個月的追蹤期間，沒有觀察到局部復發的情形。在文獻回顧中，不曾有過類似的多發性胸壁脂肪肉瘤的報告。

We present a rare case of multifocal liposarcomas that originated in the chest wall. A 61-year-old woman palpated a mass lesion in her left chest wall, at the subclavicular area. Intermittent local tenderness and radiation pain to the left arm were noted. On physical examination, an elastic and mobile tumor measuring 5×3 cm was palpated in the left chest wall. Ultrasonic examination revealed that the tumor was well defined and heterogenous in density. Under the impression of a chest wall lipoma, she underwent excision of the tumor. After removing the superficial larger tumor, another deep, dumbbell-shaped tumor was found by finger palpation. Excision of the deeper tumor was performed, as well. Histopathological findings revealed that the tumors were well-differentiated, sclerosing liposarcomas containing cells with atypia, hyperchromatic nuclei and occasional lipoblasts. During 12 months of follow-up, no local recurrence was noted. There has been no report in the literature of chest wall liposarcomas presenting as multifocal tumors.
