We experienced two cases of multiple basal cell carcinomas (BCCs) in proximity to one another on one side of the neck. Both patients were referred to us on suspicion of malignant melanoma with intransit metastases. In the first case, we were unable to distinguish the lesions from malignant melanoma preoperatively. They were found to be BCCs after resection of all the lesions as a single mass. As we experienced the first case and some of the lesions of the second case were superficial ones, we diagnosed the lesions of the second case as BCCs. Multiple BCCs in proximity should be recognized as a disease that requires differentiation from malignant melanoma with in-transit metastases. Skin Research, 21 : 10-14, 2022
