A 46-year-old man presented with an extremely painful, 1 cm, mobile, nodular mass located on the medial side of his right elbow. Symptoms failed to respond to conservative treatment. Ultrasound and Doppler flow imaging revealed a well-defined, round hypoechoic mass. Under local anesthesia, the mass was resected and the wound closed without complication. Final pathology diagnosed the lesion as a glomus tumour, solid type. Histology staining showed the tumour cells were positive for antibodies to vimentin and muscle actin. It is unusual for a glomus tumour to be located anterior to the medial epicondyle of the right arm. Hand surgeons most commonly encounter glomus tumours in the nailbeds of the fingers.
一名46岁男性患者，其右肘内侧出现一个极其疼痛的、1厘米大小的可移动结节状肿块。保守治疗无效。超声和多普勒血流成像显示为边界清晰的圆形低回声肿块。在局部麻醉下，切除肿块，伤口缝合，未出现并发症。最终病理诊断该病变为实体型血管球瘤。组织学染色显示肿瘤细胞波形蛋白和肌动蛋白抗体呈阳性。血管球瘤位于右臂内上髁前方并不常见。手外科医生最常遇到的血管球瘤位于手指甲床。
