Basal-cell carcinoma most commonly occurs in men in the fifth to seventh decades of life. The area of the lesion is usually one that has frequent exposure to the sun: the middle third of the face and upper lip. An unusual case of basal-cell carcinoma occurring on the lower lip and involving the commissure in a 21-year-old woman is presented. The surgical procedures for resection of the tumor and reconstruction of the commissure are described.
基底细胞癌最常发生于50至70岁的男性。病变部位通常是经常暴露于阳光下的部位：面部中三分之一和上唇。本文介绍了一例发生在下唇并累及口角的基底细胞癌罕见病例，该病例发生在一名21岁女性身上。文中描述了肿瘤切除和口角重建的手术过程。
