Renal-cell carcinoma develops as an insidious neoplasm, frequently metastasizing to the skin. Cutaneous manifestations vary regarding morphology and sites of predilection. A patient was recently seen demonstrating a metastasis from a renal neoplasm. The lesion was unusual in that it grossly resembled a cutaneous horn. Dermatologists should continue to be alert to the possibility of renal tumor metastasis when evaluating cutaneous tumors.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
