A Breast Lump in an Elderly Lady - Carcinoma or else ?.

Abstract

Breast tuberculosis (TB) is rare form of extra-pulmonary TB. It is most commonly seen in women of reproductive age group, especially in young, multiparous women who are breast feeding. In geriatric women, breast TB in some cases simulates with breast carcinoma due to common signs which include hard breast lump with nodular surface, ulceration, fixity to skin, discharging sinus, retraction of nipple, axillary lymphadenopathy etc. Hence, it is very difficult to differentiate breast TB from breast cancer, especially in elderly women on clinical ground only, and therefore, histopathological diagnosis is mandatory. Fine needle aspiration cytology is frequently inconclusive due to very small amount of tissue material, and open biopsy or lumpectomy followed by histopathological examination is necessary to confirm the diagnosis of breast TB. Six-month course of anti-tuberculous therapy - ATT (rifampicin, isoniazid, pyrazinamide and ethambutol) is adequate for complete resolution. Here, we report a case of breast TB in an elderly women presenting with left sided breast lump with ulceration of overlying skin and ipsilateral axillary lymphadenopathy. This case of tuberculous mastitis was suspected to be carcinoma due to presence of hard, tender, breast lump with irregular margin, nodular surface, ulceration, purulent discharge and ipsilateral axillary lymphadenopathy in absence of any constitutional symptoms of TB, and heterogenous, hypoechoic mass on USG, which was confirmed by histopathological examination of resected breast lump and responded fully to ATT.
