Colon carcinoma cutis: a case report.

The occurrence of cutaneous metastasis from colon cancer is rare especially when located on the extremities. Cutaneous metastasis typically signifies widespread disease and poor prognosis. Although uncommon, carcinoma cutis must be considered in any patient with a history of carcinoma who presents with a new skin eruption. Diagnostic biopsy is essential, inasmuch as the appearance of these lesions is not distinctive. We present a patient with known colon cancer and the new onset of papules on her right lower extremity.
