Leiomyosarcomas arising from the wall of the blood vessels, are highly malignant tumours. Although 75% of the cases have been reported in the inferior vena cava, nevertheless scanty mention is made in the literature of an analogous tumor originating from smaller blood vessels. This paper deals with a 53-year-old man with a tumor in the right axilla. Surgery consisted in wide local excision. Histopathology revealed a mesenchymal tumor in an axillary blood vessel. Electron microscopy revealed tumor cell with all the characteristics of a leiomyosarcoma. The patient refused adjuvant therapy and died 10 months later with local recurrence and lung metastases.
起源于血管壁的平滑肌肉瘤是高度恶性肿瘤。尽管75%的病例报道发生在下腔静脉，但文献中对起源于较小血管的类似肿瘤提及甚少。本文报道一名53岁男性，其右腋窝有一肿瘤。手术方式为广泛局部切除。组织病理学显示腋窝血管中有一软组织肿瘤。电子显微镜检查显示肿瘤细胞具有平滑肌肉瘤的所有特征。患者拒绝辅助治疗，10个月后因局部复发和肺转移死亡。
