ABSTRACT

Metastases to the skin from internal malignancy is rare condition which range from 0.7 to 9%. Because skin metastases sometimes represent the first sign of malignancy from an unknown primary origin and managing primary carcinoma may be mandated by detection of cutaneous metastases, it is important to recognize the clinical and histopathologic features of the metastatic skin cancer. Male breast cancer is uncommon disorder and cutaneous involvements in male breast cancer show various clinicopathologic types. We report 49-year-old man presented with a diffuse morphea-like induration on neck, chest and upper back which turned out to be carcinoma en cuirasse originating from breast cancer.
