A 60-year-old woman developed an avascular leiomyoma arising from a digital artery in the thumb and was successfully treated by en bloc excision. Leiomyomas in the hand are very rare, and thus the diagnosis will seldom be made on clinical evaluation. They may be more painful than other common, benign tumors, however, and may originate from a digital artery. Preoperative evaluation of vascular function may give a clue to the presence of a leiomyoma. A spectrum of vascular smooth-muscle tumors from very vascular to relatively avascular is noteworthy.
一名60岁女性的拇指指动脉出现了一个无血管平滑肌瘤，通过整块切除成功治愈。手部平滑肌瘤非常罕见，因此很少能通过临床评估做出诊断。然而，它们可能比其他常见的良性肿瘤更疼痛，并且可能起源于指动脉。术前对血管功能的评估可能提示平滑肌瘤的存在。值得注意的是，存在一系列从血管丰富到相对无血管的血管平滑肌肿瘤。
