title: Cutaneous Metastases simulating other dermatoses.
abstract: Two patients with unusual cutaneous metastases from internal cancer are presented herein. In a patient with breast cancer, cutaneous metastases developed which appeared as erythema annulare centrifugum. A patient with prostatic cancer had cutaneous metastases which mimicked pyodermas. The importance of skin biopsy as a diagnostic tool is emphasized.
