Subungual glomus tumors are uncommon tumors that present with a classic triad of temperature sensitivity, pain, and localized tenderness. Different surgical approaches can be performed according to the anatomic location of the tumor.
To investigate the outcome of surgical excision of subungual glomus tumors according to anatomic location.
The records of 22 Korean patients diagnosed with subungual glomus tumor by histopathologic examination who underwent surgical excision over a 7-year period (2005-2011) were retrospectively reviewed. Local complications including persistence of symptoms, surgical methods, and tumor recurrence were evaluated through long-term follow-up.
In the 22 patients, 13 tumors were located in the nail matrix and nine in the nail bed. No recurrence was observed after a mean follow-up of 36.6 months. Eight of the 13 patients with nail matrix involvement had complications such as nail deformity, decreased sensation, and prolonged pain sensation, whereas only one of the nine patients with nail bed lesion had prolonged pain sensation.
Careful dissection and complete removal of the tumor offered cure without recurrence; anatomic location of the subungual glomus tumor at initial presentation may predict postoperative complications.
甲下血管球瘤是一种少见的肿瘤，其临床表现具有典型三联征，即温度敏感性、疼痛和局部压痛。根据肿瘤的解剖位置，可以选择不同的手术方法。
探讨根据解剖位置行甲下血管球瘤切除术的疗效。
回顾性分析 2005 年至 2011 年期间经组织病理学检查确诊为甲下血管球瘤并行手术切除的 22 例韩国患者的临床资料。通过长期随访评估局部并发症（包括症状持续存在、手术方法和肿瘤复发）。
22 例患者中，13 例肿瘤位于甲母质，9 例位于甲床。平均随访 36.6 个月后，无肿瘤复发。13 例甲母质受累患者中有 8 例出现并发症，如指甲畸形、感觉减退和疼痛持续时间延长，而 9 例甲床受累患者中仅有 1 例出现疼痛持续时间延长。
仔细解剖和彻底切除肿瘤可治愈且无复发；肿瘤的初始解剖位置可能预测术后并发症。
