Cutaneous metastasis of breast carcinoma mimicking malignant melanoma in scalp.

Cutaneous metastases of carcinoma of the breast may present a broad spectrum of clinical and histologic appearances. Pigmented metastases of a breast carcinoma have rarely been described in the literature and these metastases are usually located on the chest and abdominal wall close to the mastectomy scar. We report an unusual case of a cutaneous metastasis of carcinoma of the breast simulating malignant melanoma.
