Extradigital glomus tumour is uncommon, little-known outside of its subungual location, and may present without its classic triad of tenderness, cold sensitivity and paroxysmal pain. Imaging is non-specific and diagnosis is often delayed, sometimes for years, leading to unnecessary morbidity. Surgical excision is the treatment of choice, although technique depends on case specifics. Histological subtypes depend on the relative prominence of glomus cells, vascular structures and smooth muscle. The vast majority of glomus tumours are benign. We highlight the importance of considering extradigital glomus tumours when generating differential diagnoses of an atypical painful lesion in a variety of clinical specialties.
指外血管球瘤并不常见，除了甲下部位外鲜为人知，并且可能不表现出其典型的三联征，即压痛、冷敏感和阵发性疼痛。影像学表现不具有特异性，诊断常常延迟，有时长达数年，导致不必要的发病率。手术切除是首选治疗方法，不过技术取决于具体病例情况。组织学亚型取决于血管球细胞、血管结构和平滑肌的相对突出程度。绝大多数血管球瘤是良性的。我们强调在各种临床专科对非典型疼痛性病变进行鉴别诊断时，考虑指外血管球瘤的重要性。
