Metastatic Cutaneous Squamous Cell Carcinoma of the Colon Presenting as Transfusion-Dependent Hematochezia.

Squamous cell carcinoma (SCC) of the colon is an exceedingly rare clinical diagnosis with few cases reported in the literature. We report a case of a 61-year-old man with a medical history of cutaneous SCC of the penis who presented with hematochezia and was found to have metastatic SCC to the distal transverse colon. To our knowledge, this is the first case of colonic SCC presenting as a metastatic disease from a primary penile site.
