title: Invasive breast carcinoma with granulomatous stromal response.
abstract: An unusual case of invasive ductal carcinoma of the breast associated with epitheloid granulomas is reported. Multinucleated giant Langhans'-type giant cells were found in the epitheloid granulomas in breast carcinoma, but there were not present in the breast tissue and axillary lymph nodes. Congo-red deposits were found haphazardly in the stroma between tumor cells and granulomas. Numerous mast cells were found surrounding granulomas. The patient lacked any clinical evidence of the systemic granulomatous disease. The presence of epitheloid granulomas, amyloid deposits and numerous mast cells in invasive breast carcinoma could be related to a host immune response towards the tumor.
