[Report of a case of trichophyton fungus granulomatosis of the breast and its differential diagnosis to inflammatory carcinoma (author's transl)].

The case of a 34 year old patient is reported who suffered from a chronic dermatatomycosis. The trichophyton fungus granula matosis secondarily invaded the parenchyma of the breast and clinically first presented with signs and mammographic findings suggestive of an inflammatory carcinoma. A similar case report was not located in the international literature. Therefore the clinical and mammographic details and the conclusive microscopic findings of the biopsy of this case are reported for the purpose of differential diagnosis.
