To date, a detailed analysis, in terms of their locational association and histogenesis, has not been fully documented [7]. Here, we describe a case of BCC with a neighbouring melanocytic nevus on the nose. We elucidated how both lesions overlapped based on double-immunostaining for Ber-EP4 and S-100. In addition, we emphasize the critical [...]
