title: Perineural cell differentiation in ganglioneuromas.  Report of 8 cases with immunohistochemical  expression of perineural cell markers.
abstract: Eight cases of ganglioneuroma were examined for a presence of perineural cell differentiation, using the immunohistochemical markers epithelial membrane antigen (EMA), claudin-1 and GLUT-1. The mean age of the patients was 42.3 years (range 26-68 years), six patients were females and two were males. Five tumors were located in the adrenal gland and 3 tumors in the retroperitoneum. Morphology of the tumors was typical, i.e., they were composed of neuroid spindle cell population and scattered mature appearing ganglion cells. Spindle cells positive for perineural cell markers claudin-1 and GLUT-1 were found in all lesions, at least focally. EMA+ cells were seen in 2 of 8 tumors. These perineural-type cells were often arranged in organoid fashion around the schwannoid bundles or around the vessels. Our findings indicate that perineural cell differentiation is commonly present in ganglioneuromas.
