Breast cancer is the second most common cancer diagnosed in women. Skin metastases result from infiltration of the skin due to cell proliferation. The incidence of cutaneous metastases varies from 0.6-10.4%. We present a 52-year-old woman diagnosed with infiltrating ductal carcinoma triple-negative, who presented with a localized dermatosis that affects the chest with a erythematous plaque, nodular and ulcerated in appearance, with irregular and well-defined edges. Breast carcinoma can present metastases in skin, recognizing the diversity of clinical presentations in a timely manner, is the key to a timely diagnosis and reducing mortality.
