摘要

平滑肌肉瘤是一種影響子宮和腸胃道為主的惡性軟組織腫瘤。原發性肺部平滑肌肉瘤更是非常罕見。診斷前必須先排除其他原發部位。目前在全世界曾經被報導的病例不到一百個。大部分被報導的病例都只有單側肺部病灶，只有少數的病例在診斷時已經有兩側肺部病灶。本病例是一個以兩側肺部病灶為表現的平滑肌肉瘤，而且沒有發現其他原發部位。儘管病人剛開始時的狀態不錯，其預後卻因無法切除而很差。我們只能給予姑息性的化學治療。最終病人還是因疾病而死亡。

Leiomyosarcoma is a malignant soft tissue tumor predominantly affecting the uterine and gastrointestinal tract. Primary pulmonary leiomyosarcoma is very rare. It is diagnosed only after other primary origins have been excluded. Less than 100 cases have been reported worldwide in the literature. Most of the reported cases involved a unilateral lung, and only a few cases had bilateral lung involvement on diagnosis. We herein report a case of pulmonary leiomyosarcoma with bilateral lung involvement and no other detectable primary origin. Although the patient had a good performance status initially, the poor prognosis was inevitable in this unresectable condition. Palliative chemotherapy was given. Ultimately, the patient succumbed to the disease.
