Fine needle aspiration diagnosis of tuberculous mastitis.

Fine needle aspiration cytology has become the first choice in diagnostic procedures in the management of a variety of breast diseases. The technique can be successfully used to diagnose granuloma in breast aspirates and to demonstrate the presence of acid-fast bacilli. Tuberculosis is rampant in developing countries and patients are prescribed antituberculous therapy on the basis of finding granuloma in breast aspirates without a culture report. In our practice, this principle has been followed with excellent results. In our experience, this technique was reliable and reproducible in diagnosing tuberculous mastitis. We report on the cytomorphological findings of this uncommon but important disorder.
