Cutaneous metastasis of colon cancer: case report and literature review.

Cutaneous metastases arising from an internal malignancy are a rare phenomenon, occurring in 0.001% of all skin biopsies performed. Of these, 6.5% originate from the a primary colon cancer. Colon cancer, when metastatic to the skin, typically appears as a painless flesh-colored nodule or as a mass with occasional ulceration. We report a case of a large cutaneous metastasis to the suprascapular region as the initial presenting symptom of an underlying colon cancer.
