Metaplastic carcinoma breast in male – A case report and review of literature

Male breast cancers are rare and account for 1% of all breast cancer cases reported annually. Incidence of metaplastic breast cancer in females is less than 1% thus metaplastic breast cancers in males are even rarer. Larger tumour size and higher grade differentiate them from invasive carcinoma. They are also more aggressive than invasive carcinoma. On IHC these are typically oestrogen- and progesterone-receptor, Her 2 neu negative. Here we report a rare case of a 35-year-old male patient who presented with left chest wall swelling for six months, histopathological examination showed it to be metaplastic carcinoma breast. The patient underwent left MRM and adjuvant chemotherapy.
