Cytodiagnosis of a spindle-cell tumor of the breast using antisera to epithelial membrane antigen.

A case of an unusual breast tumor is described in which the smear from a fine needle aspiration (FNA) biopsy caused difficulty in differentiating between a spindle-cell carcinoma and a sarcoma. The problem was resolved by the immunoperoxidase demonstration of epithelial membrane antigen (EMA) in the cells, thus enabling a definitive diagnosis of spindle-cell carcinoma to be made. This case further demonstrates the utility of demonstrating EMA in FNA specimens to distinguish between epithelial and nonepithelial neoplasms.

Lymphoid hypophysitis associated with sudden maternal death: report of a case review of the literature.

A case of lymphoid hypophysitis in a woman who died during labor is presented. From a review of the 14 previously reported cases it is apparent that this is a specific disease entity, that it involves only woman, especially in association with pregnancy, and that it may have a fatal outcome. The clinical manifestations are either related to hypopituitarism, or those of a space occupying lesion.
