Primary Breast Tuberculosis Presenting as a Lump: A Rare Modern Disease

Abstract

Breast tuberculosis is an uncommon form of entity especially in the infra-mammary area. A 25- year-old female, presented with a lump in the breast and infra-mammary area. She was having off and on fever without any other complaints. There was no positive family history. Primary breast tuberculosis was diagnosed on fine needle aspiration cytology wherein ZN stain for acid fast bacilli was positive. The patient received antitubercular drugs and at 3 month follow up the swelling had resolved and the patient was asymptomatic. Breast tuberculosis is a rare disease with non-specific clinical, radiological, and histological findings. Misdiagnosis is common as biopsy specimens are pauci-bacillary and investigations such as microscopy and culture are frequently negative.
