血管球瘤是罕见的血管错构瘤，最常见于手指的甲下区域。它们表现为典型的三联征：阵发性疼痛、点压痛和冷敏感。由于对这种情况的认识不足，诊断常常被错过数年。一名 42 岁女性，有多年中指被击打或受凉时疼痛的病史。她的指甲有点压痛，指甲弯曲度增加。磁共振成像 (MRI) 显示甲下血管球瘤 7 毫米。通过经甲方法切除肿瘤，完全缓解了她的疼痛。血管球瘤是根据典型症状和阳性激发试验的存在进行临床诊断的。这些测试包括触诊时的点压痛和冰敷在手指上时的疼痛。当诊断不清楚或在手术前定位肿瘤时，可以使用 MRI 成像。提高医生对这种情况的认识可以减少诊断和治疗的时间。版权所有©南达科他州医学协会。

Glomus tumors are rare vascular hamartomas most commonly found in the subungual region of the fingers. They present with a classic triad of paroxysmal pain, point tenderness, and cold sensitivity. The diagnosis is often missed for several years due to under recognition of this condition. A 42-year-old female presented with a several year history of pain in the middle finger when it was struck or exposed to cold. She had point tenderness on the fingernail, and increased curvature of the nail. Magnetic Resonance Imaging (MRI) revealed a 7mm subungual glomus tumor. The tumor was surgically excised via a transungual approach, resulting in complete relief of her pain. Glomus tumors are diagnosed clinically based on the presence of classic symptoms and positive provocative tests. These tests include point tenderness on palpation and pain when ice is placed on the digit. MRI imaging can be used when the diagnosis is unclear or to localize the tumor prior to surgery. Increased awareness of this condition among physicians could reduce the time to diagnosis and treatment.Copyright© South Dakota State Medical Association.
