Perianal basal cell carcinoma (BCC) is a rare lesion that accounts for less than 0.08% of all BCCs. It is challenging to diagnose, as it can be overlooked or mistaken for an inflammatory dermatosis. When discovered early and treated properly, BCC is associated with low mortality and a good prognosis. Thorough total-body skin examinations and biopsy of suspected lesions found in the perianal region is recommended. We present a case of a superficial nodular perianal BCC that was discovered following a routine total-body skin examination and was treated with Mohs micrographic surgery (MMS). Patient nonattendance is also discussed.
肛周基底细胞癌（BCC）是一种罕见病变，占所有基底细胞癌的比例不到0.08%。其诊断具有挑战性，因为它可能被忽视或误诊为炎症性皮肤病。早期发现并妥善治疗时，基底细胞癌的死亡率较低且预后良好。建议对肛周区域进行全面的全身皮肤检查，并对疑似病变进行活检。我们报告一例浅表结节性肛周基底细胞癌病例，该病例在常规全身皮肤检查后被发现，并接受了莫氏显微外科手术（MMS）治疗。同时也讨论了患者未就诊的情况。
