A 75-year old man noticed black spots on the scrotal and inguinal regions two years before the first visit. They gradually enlarged and bled, and he came to our department. At the first visit, dark red and light black pigmented plaques with black spots and erosions were noted on the right scrotal and left inguinal regions, respectively. We diagnosed these pigmented plaques as basal cell carcinoma (BCC) by skin biopsy. We next performed a whole-body skin examination and found a brown plaque with black spots on the posterior region of the right auricle. It was suggested to be BCC by dermoscopy. We surgically resected these 3 lesions and confirmed them all to be BCC histologically. Four years and five months after the surgery, no recurrence or new BCC lesion has developed. We examined 375 specimens from 335 cases of BCC at our hospital between 1991 and 2019, and confirmed 19 cases of multiple BCC. In the present case, we first diagnosed two BCC lesions, and after checking the entire body, we found an additional BCC. Whole-body examination and long term follow-up are important to find new BCC lesions and recurrence when patients have multiple BCC. Skin Research, 19 : 31-37, 2020
