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.
血管球瘤是一种罕见的血管错构瘤，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、压痛和冷敏感。由于对这种疾病的认识不足，诊断常常会被漏诊数年。一名 42 岁女性因中指受到撞击或暴露于寒冷而出现数年疼痛。她的指甲有压痛，指甲弯曲度增加。磁共振成像（MRI）显示 7 毫米甲下血管球瘤。肿瘤通过经甲途径手术切除，疼痛完全缓解。血管球瘤的诊断基于存在典型症状和阳性激发试验。这些试验包括触诊时压痛和将冰放在指头上时疼痛。当诊断不明确或在手术前定位肿瘤时，可以使用 MRI 成像。提高医生对这种疾病的认识可以减少诊断和治疗的时间。
