抄録 <p>Glial fibrillary acidic protein (GFAP) was purified from human spinal cord and cerebral white matter. GFAP was localized by an immuno-peroxidase method in normal adult and fetal human brains, rat brains, and 152 central nervous system (CNS) tumors. GFAP was found in reactive and normal astrocytes, immature cells of fetal brain at the 18th to 21st gestational weeks, and normal rat astrocytes. This GFAP staining was quite specific for glial tumors, including astrocytomas, glioblastomas, astroblastomas, and ependymomas. GFAP-positive cells were also found in oligodendrogliomas and choroid plexus papillomas, and they were interpreted as being astroglial or ependymal differentiations. Stromal cells in cerebellar hemangioblastomas were negative. However, engulfed astrocytes were found at the periphery of such tumors and often adjacent to the proliferate blood vessels. In meningiomas, neurinomas, metastatic carcinomas, pituitary adenomas and other non-glial tumors, GFAP-positive cells were not identified.</p>

抄録 <p>We experienced a patient with traumatic neuroma of the gallbladder with no history of gallbladder surgery or cholelithiasis. A 74-year-old man was referred to our department after a gallbladder tumor was incidentally discovered during a preoperative screening examination for prostate hypertrophy. Ultrasonography, MRI, CT and endoscopic retrograde cholangiography revealed a protuberant lesion of the gallbladder. Laparoscopic cholecystectomy was attempted but adhesion between the liver and duodenum forced us to convert to open laparotomy. Cholecystectomy and adjacent liver tissue resection was performed. Diagnosis was made by frozen histology during operation. It revealed no malignancy. Postoperative pathological examination revealed traumatic neuroma associated with inflammation. To our knowledge, this is the first reported case of gallbladder neuroma without a history of gallstones or surgery in the English and Japanese literature since 1980. This traumatic neuroma should be considered in a differential diagnosis in treating gallbladder neoplasm, even in the absence of an operative history or cholelithiasis.</p>
