ABSTRACT
We report a case of malignant granular cell tumor of the chest wall that recurred in the right breast with axillary lymph node metastases. The recurrent tumor clinically and grossly mimicked a breast carcinoma. Electron microscopy and immunohistochemical techniques were used to confirm the cytologic and histologic diagnosis of granular cell tumor. The importance of true metastases in the diagnosis of malignant granular cell tumor and their differential diagnosis are discussed.

The Wellcolex Colour Salmonella and Shigella tests are rapid latex agglutination procedures for grouping Salmonella and Shigella using an antibody attached to multicolored latex particles. The tests correctly grouped 46 (100%) of 46 Salmonella clinical isolates in groups A through E and G, 42 (100%) of 42 Shigella clinical isolates, and seven (88%) of eight Shigella stock cultures. The stock culture missed had been passed through many transfers and may have lost some of its antigenicity. The Wellcolex Colour Salmonella test was also found useful in detecting and grouping Salmonella spp. directly from blood culture bottles.
