Angioleiomyomas are rare smooth-muscle tumors that occur anywhere in the body. We present the case of a 46-year-old woman with a 3-year history of a painless angioleiomyoma in the right-hand fourth web space with the typical histologic features of tortuous vascular channels and thick muscular walls. In the 39 cases of angioleiomyoma of an extremity treated at the Mayo Clinic, we found a male-to-female ratio of 1:2.2, a mean age of 52 years, and pain as the presenting symptom in 67 percent of the patients. The lesions usually were less than 1 cm in diameter, and they decreased significantly in size with increasing patient age. Simple excision was curative. Angioleiomyoma should be considered in all patients with nodular lesions of an extremity.
血管平滑肌瘤是一种罕见的平滑肌肿瘤，可发生于身体任何部位。我们报告了一例46岁女性病例，其右手第四指蹼间隙有无痛性血管平滑肌瘤，病史3年，具有典型的组织学特征，即迂曲的血管通道和增厚的肌壁。在梅奥诊所接受治疗的39例肢体血管平滑肌瘤病例中，我们发现男女比例为1:2.2，平均年龄为52岁，67%的患者以疼痛为首发症状。病变直径通常小于1厘米，且随着患者年龄的增加，其大小显著减小。单纯切除可治愈。所有肢体出现结节性病变的患者均应考虑血管平滑肌瘤。
