Metástasis en mama de melanoma maligno cutáneo

Breast metastases from extramammary primary tumors account for 2% of all malignant breast tumors (the most common being lymphoma and malignant melanoma) and can mimic primary breast carcinoma clinically and radiologically. The prognosis of patients with metastases to the breast from solid tumors is generally poor, with 80% dying in the first year. The most widely accepted treatment is simple excision. Consequently, determining the source of metastases prior to surgery avoids further surgical procedures that will not improve prognosis. We present a case of metastases from malignant cutaneous melanoma to the breast diagnosed in the right thoracic wall and surgically excised 3 years previously.
