Colorectal cancer presenting with a cutaneous metastatic lesion on the scalp.

Abstract

Cutaneous metastases occur rarely with colorectal adenocarcinoma, accounting for approximately 5 percent of all cutaneous metastases. Cutaneous metastases from colonic cancer are most often located on the abdominal skin. The case we describe here is unusual because colorectal adenocarcinoma rarely metastasizes to the scalp. A review of the English language literature revealed only six reported cases of cutaneous metastases from a colonic adenocarcinoma to the scalp.
