Introduction. A glomus tumor is a benign vascular tumor derived from glomus cells and occurs mainly in the subcutaneous layer of the subungual or digital pulp. Extradigital glomus tumors have been reported within the palm, wrist, forearm, foot, bone, stomach, colon, cervix, and mesentery. Glomus tumors can originate from the intraosseous, intramuscular, periosteal, intravascular, and intraneural layers. However, a glomus tumor originating from the intravascular layer of the forearm is a rare condition. Case Report. A 44-year-old woman had a 7-year history of chronic pain and focal tenderness of the forearm. No hypersensitivity or sensory alterations were observed. Contrast magnetic resonance imaging (MRI) showed a mass measuring 5 × 3 × 2 mm leading to a vein. Surgical excision was performed, and the tumor was completely resected. Finding of gross examination revealed a dark-red, well-defined soft tissue tumor, and histologic examination confirmed that the mass was a glomus tumor. The patient's symptoms were completely resolved postoperatively. Conclusion. Intravascular glomus tumors rarely occur in the forearm; therefore, a thorough physical exam, comprehensive medical history, in-depth imaging, and early surgical excision upon clinical suspicion may be helpful to prevent a delayed or incorrect diagnosis.
引言。血管球瘤是一种起源于血管球细胞的良性血管肿瘤，主要发生于甲下或指腹的皮下层。已报道血管球瘤可发生于手掌、腕部、前臂、足部、骨骼、胃、结肠、宫颈和肠系膜等部位。血管球瘤可起源于骨内、肌肉内、骨膜、血管内和神经内等层。然而，起源于前臂血管内层的血管球瘤是一种罕见情况。病例报告。一名44岁女性有7年的前臂慢性疼痛和局限性压痛病史。未观察到过敏或感觉改变。对比磁共振成像（MRI）显示一个大小为5×3×2毫米的肿块通向一条静脉。进行了手术切除，肿瘤被完全切除。大体检查发现为暗红色、边界清晰的软组织肿瘤，组织学检查证实该肿块为血管球瘤。患者术后症状完全缓解。结论。血管内血管球瘤在前臂很少见；因此，进行全面的体格检查、详细的病史询问、深入的影像学检查以及临床怀疑时早期手术切除，可能有助于防止诊断延迟或错误。
