Leiomyosarcoma of the large arteries and veins is rare. In this paper, one case of primary leiomyosarcoma of the axillary vein is reported. The patient, a 66 year old man, was admitted because of a mass in the medial side of right upper arm for three years and increasingly growing. The tentative diagnosis was neurologic fibroma. A local resection was performed and the final diagnosis of leiomyosarcoma of the right axillary vein was established by pathology. So far, there are 86 cases reported in the foreign literature but only one in the Chinese literature. The neoplasm most frequently occurs in the large veins (68 cases) and approximately one half in the inferior vena cava (33/68). 18 neoplasms are originated from the large arteries and of them, 10 from the pulmonary arteries. Primary leiomyosarcoma in large veins is about four times as common as that in arteries. The primary sites in order of incidence: (1) inferior vena cava; (2) pulmonary artery; (3) other large veins and (4) other large arteries.
大动静脉平滑肌肉瘤较为罕见。本文报告1例腋静脉原发性平滑肌肉瘤。患者为66岁男性，因右上臂内侧肿块3年且逐渐增大入院。初步诊断为神经纤维瘤。行局部切除术，术后病理确诊为右腋静脉平滑肌肉瘤。国外文献报道86例，国内文献仅1例。该肿瘤最常发生于大静脉（68例），约一半发生于下腔静脉（33/68）。18例起源于大动脉，其中10例起源于肺动脉。大静脉原发性平滑肌肉瘤的发病率约为动脉的4倍。发病部位依次为：（1）下腔静脉；（2）肺动脉；（3）其他大静脉；（4）其他大动脉。
