Cutaneous leiomyoma is an infrequently occurring benign tumor that arises from smooth muscle in the skin. Pilar leiomyoma, a subtype of cutaneous leiomyoma, arises from the arrector pili muscle associated with hair follicles. Pilar leiomyoma, particularly in the head and neck region, is rare and frequently misdiagnosed. We report one patient who developed pilar leiomyoma of the nasal dorsum, explore the differential diagnosis and review the characteristics of previously reported individuals with pilar leiomyoma of the nasal dorsum.
皮肤平滑肌瘤是一种罕见的良性肿瘤，起源于皮肤中的平滑肌。毛发平滑肌瘤是皮肤平滑肌瘤的一种亚型，起源于与毛囊相关的立毛肌。毛发平滑肌瘤，尤其是在头颈部区域，较为罕见且常被误诊。我们报告了一名发生鼻背部毛发平滑肌瘤的患者，探讨其鉴别诊断，并回顾先前报道的鼻背部毛发平滑肌瘤患者的特征。
