title: Epidermoid carcinoma of the skin mimicking breast cancer.
abstract: Nonmelanoma skin cancer is the most frequent cancer in the world. Squamous cell cancer often occurs in sun-exposed areas, such as the head and neck. When it involves the breast and ulce-rates, invading the glandular parenchyma, it may mimic breast cancer. Confirmation by means of histopathological examination, combined with clinical examination, is a critical instrument for the accuracy of the diagnosis. We report a case of an epidermoid carcinoma located on the breast skin, initially diagnosed as breast cancer.
