Mixed Mucinous Male Breast Carcinoma: A Rare Histological Variant of a Rare Disease

Abstract

Male breast carcinoma is rare neoplasm, accounting for <1% of all diagnosed breast malignancy. Histologically, most often it is infiltrating ductal carcinoma and rarely mucinous carcinoma. A 73-year-old male presented with lump in right breast since six months. On examination a 5x5 cm hard, non tender lump fixed to overlying skin, with no right axillary lymphadenopathy. Incisional biopsy showed mixed mucinous carcinoma of breast. After investigations he underwent right modified radical mastectomy. Histopathology confirmed mixed mucinous carcinoma and infiltrating ductal carcinoma. Patient received adjuvant radiotherapy, chemotherapy and hormonal therapy. Mixed mucinous and infiltrating ductal carcinoma is extremely rare. Clinical stage and axillary lymph node status are of prognostic value.
