Abstract
Primary neuroblastoma of the kidney in adults is an extremely rare neoplasm that had not been described in the literature until 1986. The diagnosis can be made by histopathological examination only. We report 2 unusual cases of neuroblastoma of the kidney in adults. In both patients right nephrectomy was performed after the diagnosis of right renal cell carcinoma was made. Histological examination revealed the tumors to be primary neuroblastomas of the right kidney. In the first patient cobalt therapy was administered to the tumor bed and para-aortic area. Followup at 5 years revealed no sign of tumor recurrence. Progressive disseminated disease has been documented in the second patient despite postoperative adjuvant chemotherapy with combined cis-platinum and epipodophyllotoxin, and combined vincristine, cyclophosphamide, doxorubicin and dimethyl-tri-azeno imidazole carboxamine.
