Cutaneous leiomyoma, also known as leiomyoma cutis, is a rare presentation of an extra-uterine leiomyoma, often found on the extremities, trunk, and genitalia. Solitary lesions rarely occur on the face. This case presents a 63-year-old man with a one-year history of a growing mass in the preauricular region. On examination, a well-defined, painless mass was noted. Given the unusual yet visible location on the face, the decision was made to excise it surgically. After surgical resection, the biopsy specimen stained positively for smooth muscle actin (SMA), confirming a cutaneous leiomyoma. To the best of our knowledge, this is the eighth reported case of a preauricular cutaneous leiomyoma and stresses the importance of an accurate diagnosis for timely surgical treatment.
皮肤平滑肌瘤，也称为皮肤平滑肌瘤病，是子宫外平滑肌瘤的一种罕见表现，常出现在四肢、躯干和生殖器部位。孤立性病变很少发生在面部。本病例报告了一名63岁男性，其耳前区域有一个逐渐增大的肿块，病史为一年。检查时，发现一个边界清晰、无痛的肿块。鉴于其在面部不寻常但可见的位置，决定进行手术切除。手术切除后，活检标本平滑肌肌动蛋白（SMA）染色呈阳性，证实为皮肤平滑肌瘤。据我们所知，这是第八例报告的耳前皮肤平滑肌瘤病例，强调了准确诊断对于及时手术治疗的重要性。
