Pilomatrixoma most commonly occurs in the head and neck region, appearing primarily in the first two decades of life. The lesion is described as a tumor with differentiation toward hair cells and surgical excision is the treatment of choice.
We report an uncommon localization of a perforating type pilomatrixoma of 5 x 4 x 4 cm in size that developed from the earlobe.
Histopathological examination revealed pilomatrixoma. Total resection of the tumor was performed. The earlobe was reconstructed by forming a posterior-superior pedicled skin flap.
No recurrence was observed and a good cosmetic result was obtained.
Local recurrence does not generally occur if the tumor is completely removed. The case we present is of interest in having a history of trauma to the region and a relatively rapid growth with perforation of the overlying skin.
毛发上皮瘤最常发生于头颈部区域，主要出现在生命的前二十年。该病变被描述为一种向毛细胞分化的肿瘤，手术切除是首选治疗方法。
我们报告一例罕见部位的穿通型毛发上皮瘤，大小为5×4×4厘米，发生于耳垂。
组织病理学检查显示为毛发上皮瘤。对肿瘤进行了完整切除。通过形成后上蒂皮瓣对耳垂进行了重建。
未观察到复发，获得了良好的美容效果。
如果肿瘤被完全切除，一般不会发生局部复发。我们呈现的该病例因该区域有创伤史且生长相对迅速并穿破覆盖皮肤而具有研究价值。
