Abstract

We describe two exceptional collision tumors, namely: a 63-year-old woman revealing a melanocytic tumor within a trichoblastoma and a 71-year-old woman with a squamous cell carcinoma colonized by dendritic cells of a melanoma. Both neoplasms showed two different tumor components with intimate relationship. The lesions are labeled in a "playful" way with the acronyms METRO (MElanocytic tumor +TRichOblastoma) and CAMEL (CArcinoma +MELanoma) to facilitate memorization.
