摘要

肌內脂肪瘤是一種罕見而有其特殊臨床及病理表現的脂肪瘤類型，而發生於肋間肌肉者則未見於現有文獻之中。由於在臨床症狀和影像檢查上，我們難以區分良性肌內脂肪瘤和惡性的高度分化肌肉瘤，所以廣泛手術切除是最好的診斷與治療方式。在此一病例報告中，我們呈現一個50歲男性病患在例行胸部X光檢查中，意外發現一個右上肺野腫瘤，胸部電腦斷層顯現一個橫跨肋間的軟組織腫瘤伴隨完整的肋膜表面。病患隨後接受此胸壁腫瘤的廣泛切除。病理檢查報告為一肌內脂肪瘤。病患術後恢復良好，在5年的術後追蹤期間並無復發。除了報告此一罕見病例，我們也回顧整理現有的相關文獻。

Although subcutaneous lipoma is the most common soft tissue neoplasm, deeply-seated intramuscular lipoma is rarely encountered, especially those arising in the chest wall. Because images provide insufficient efficacy to differentiate these benign neoplasms from well-differentiated liposarcomas, excisional biopsy is often needed. Surgical results are markedly good and the recurrence rates depend on free resection margins. We present a rare case of intramuscular lipoma arising in the intercostal muscles. This tumor was found incidentally on the chest roentgenography as a large subpleural mass, and the computerized tomography revealed a well-defined tumor with fatty density straddling the intercostal space. Wide excision of this tumor was performed smoothly, followed by an uneventful course. No local recurrence was noted for 5 years. We report this case with a review of literature.
