Tuberculosis of the breast is an extremity rare disease in western countries and about 0.5% among entire breast in Korea and most of which involved persons between 20 to 40 years of age in female but it rarely developed in male, elderly patient and prepubertal woman. It may be primary-confined to the breast or secondary to tuberculosis elsewhere because of it's diagnostic difficult. Tuberculosis of breast, is confused to actinomycosis infection, abscess and carclnom.

So, it is only diagnosed by histopathologic finding or inoculation in experimental animal. I expirienced 3 cases of tuberculosis of the breast in 23 years which were treated with antibiotics, antituberculosis medication and combined with surgical excision.
