The most commonly diagnosed cancer and the leading cause of cancer mortality in women worldwide is carcinoma breast. They are broadly classified into invasive breast carcinoma- no specific type and special types; among which is tubular carcinoma (TC) which we encountered. A 66 year old post- menopausal female presented with swelling in the right breast which on mammography and cytology was diagnosed as malignancy. A modified radical mastectomy (MRM) was done. Histopathology revealed an infiltrating carcinoma with predominantly tubular differentiation (>90%) leading to the diagnosis of pure TC breast. Immunohistochemistry showed strong positivity for oestrogen receptors(ER), progesterone receptors (PR) and negativity for Her 2 typically seen in TC. The patient was started on tamoxifen therapy post diagnosis and was doing well but was subsequently lost to follow-up. The early detectability and diagnosis on mammography, characteristic histopathological findings and excellent prognosis makes the diagnosis of these malignancies of prime importance.
