Granular Cell Tumor in the Ascending Colon

概要

論文の詳細を見る
We describe a case of multiple polypoid lesions that occurred in the colon of a 62-year-old man. Eight of the lesions were demonstrated by barium enema, and five were examined histologically. A small nodule in the submucosa of the ascending colon was histologically identical to granular cell tumor, characterized by nested growth of large tumor cells with ample granular cytoplasm and small round nuclei. Immunohistochemically, the cells were positive for S-100, neuron-specific enolase and vimentin, and negative for α-smooth muscle actin and desmin.(Internal Medicine 34: 657-660, 1995)
