Adult-type ganglioneuroblastoma in the adrenal gland treated by a laparoscopic resection: report of a case

Abstract

A case of ganglioneuroblastoma in the adrenal gland of a 50-year-old man is reported. The patient was incidentally found to have a nonfunctioning tumor in the right adrenal gland. The tumor, measuring 4.5 cm, was successfully removed using laparoscopy. Histologically, the tumor was diagnosed to be a ganglioneuroblastoma. Immunohistochemically, a few MIB-1-positive cells and no S-100 protein-positive cells were observed. There has been no evidence of recurrence for 2.5 years to date after the operation. Adrenal ganglioneuroblastoma is extremely rare in adults, and only seven such cases have been previously reported in the literature.
