Breast tuberculosis was originally classified by McKeon et al (7) into the following categories: (a) acute miliary type--rare, due to blood borne infection in miliary tuberculosis; (b) nodular type the most common type, which presents as a localized lump with or without sinuses in one quadrant of the breast; (c) disseminated type--involving the entire breast with multiple sinuses; (d) sclerosing type--minimal caseation and extensive hyalinization of the stroma, shrinkage of the breast tissue with early skin retraction and late sinus formation; clinically this type is indistinguishable from carcinoma; and (e) tuberculous mastitis obliterans--a rare form due to intra ductal infection with fibrosis and obliteration of the ductal system; sinus formation is infrequent.
