[Cytologic diagnosis of tuberculous mastitis. Report of a case and review of the literature].

A case of breast lump is reported in a 42-year old woman, clinically simulating carcinoma. A fine-neddle aspiration biopsy was performed, the cytology showing granulomatous inflammatory process and Mycobacterium tuberculosis. Review of the literature was undertaken and discussed with regard to incidence, clinical presentation, mode of infection, classification, treatment and diagnosis of tuberculous mastitis, focusing on the fine-needle aspiration biopsy as a diagnosis procedure and the cytologic examination findings in tuberculous mastitis.
