title: Neurofibroma of the gallbladder seen as a papillary polyp.
abstract: A case of neurofibroma of the gallbladder in a 44-year-old woman without von Recklinghausen neurofibromatosis but with right hypochondralgia is reported. The tumor was seen preoperatively as a polypoid lesion and in the resected gallbladder as a papillary polypoid growth over the main intramural tumor mass. Microscopically, the tumor was identified as a neurofibroma with many tactile corpuscle-like structures (Wagner-Meissner bodies), which were found by electron microscopic and immunohistochemical examination to consist of Schwann cells. Twelve cases of non-epithelial neoplasms arising in the gallbladder are also reviewed.
