Metastatic breast carcinoma mimicking granular cell tumor.
Metastatic breast carcinoma may assume many patterns. We describe a case in which cutaneous, pulmonary and lymph node metastases of an adenocarcinoma of the breast all resembled granular cell tumor. In all sites, the lesion stained positive with antibodies against EMA and cytokeratins, but failed to stain with anti-S100.
