T-Cell Rich B-Cell Lymphoma Of The Breast: A Rare Case Report With Emphasis On The Role Of Immunohistochemistry In The Diagnosis

ABSTRACT

Primary breast lymphoma is one of the rare tumors that commonly presents as a lump with <0.5% incidence rate. It may be misdiagnosed as poorly differentiated carcinoma on routine fine-needle aspiration cytology. With appropriate treatment, this breast malignancy has a relatively better prognosis. Here, we report the case of a mammary T-cell rich B-cell non-Hodgkin lymphoma in a pre-menopausal woman diagnosed by biopsy and later confirmed by immunohistochemistry.
