Granulomatous mastitis - an uncommon finding


A 19-year-old female came with complaints of multiple lumps in her right breast of different sizes, which she had noticed one month back. The woman also gave a lactating history and family history of tuberculosis. After obtaining informed consent from the patient, minimally invasive procedure, Fine Needle Aspiration Cytology (FNAC) was performed and about 2 ml of pus like material was aspirated. Giemsa stained microscopic finding showed epithelioid cells along with lymphocytes in a necrotic background that were consistent with Granulomatous mastitis. Sometimes epithelial atypia can be worrisome in cases of mastitis. Hence clinical correlation is necessary along with cytological findings for interpretation. Open biopsy is the gold standard for definitive diagnosis.
