title: Primary colonic adenocarcinoma diagnosed with cutaneous shave biopsy.
abstract: A 67-year-old man presented to the emergency department with chronic weakness, fatigue and failure to thrive. On physical examination, he was found to have multifocal exophytic cutaneous masses in the pubic and scrotal regions. We obtained a shave biopsy, and subsequent histopathology demonstrated non-native tissue consistent with metastasis from a primary adenocarcinoma. We report this novel case of anogenital cutaneous metastases of colorectal adenocarcinoma.
