Glomus tumors are benign neoplasms that develop from normal glomus bodies. These tumors are most commonly found in the nail bed of the hands and are characterized by point tenderness, and temperature sensitivity. Histologically, they are classified into three groups, the least common is glomangiomyoma, which is a variant distinguished by its predominant smooth muscle cellular content. This report describes a patient with a subungual glomangiomyoma that was surgically excised with a favorable outcome. The tumor is unusual for this location; a location common for typical glomus tumors. It presented without the typical associated symptoms of point and temperature sensitivity. This may suggest that the histological type may be more important in predicting the clinical presentation than the anatomical location of the glomus tumor.
血管球瘤是起源于正常血管球的良性肿瘤。这些肿瘤最常见于手部甲床，其特征为点状压痛和温度敏感性。在组织学上，它们分为三组，最不常见的是血管球肌瘤，这是一种以平滑肌细胞成分为主的变异型。本报告描述了一名患有甲下血管球肌瘤的患者，该肿瘤通过手术切除，预后良好。该肿瘤在此位置不常见；典型血管球瘤常见于此位置。它没有出现典型的点状压痛和温度敏感相关症状。这可能表明，在预测临床表现方面，组织学类型可能比血管球瘤的解剖位置更重要。
