title: Granular cell tumor of the gallbladder. Report of a case.
abstract: A rare case of granular cell tumor of the gallbladder in a 58-year-old Japanese man is presented. This is the third report of such a tumor arising in the gallbladder. The immunohistochemical study demonstrated the localization of the nervous-system-specific protein (S-100 protein) in the granular component cells, thereby supporting the Schwann cell origin of this tumor.
