Unusual Presentation of Breast Metastasis Mimicking Skin Abscess

Abstract

The primary malignant tumor that most commonly metastasizes to the skin in women is breast cancer and manifest variety forms of clinical presentation. Breast cancer has the ability to metastasize to any site such as the ovaries, lung, liver, bone, brain, gastrointestinal tract and skin. The skin is not a common site for metastatic spread. We would like to report a case of a 56 years old female patient with an infectious mass in her left inframammary fold with discharge. The patients had a one-year history of left breast pruritus and with a mass which increased in size over two months. There was axillary lymphadenopathy, tenderness, and erythema of breast skin around the mass in the physical examination and just elevated erythrocyte sedimentation rate in laboratory tests. The patient did not benefit from antimicrobial therapy. The histological examination revealed a tumor with sheets of malignant cells and many necrotic areas. The diagnosis was invasive ductal breast carcinoma, cutaneous metastases, and lymphatic embolization.
