title: [A case of adult neuroblastoma arising in the retroperitoneal space].
abstract: Neuroblastoma, common in children, rarely develops in adults. We recently treated a patient with adult neuroblastoma. A 34-year-old man complained of a swelling in right inguinal region. CT scan showed swelling of retroperitoneal and inguinal lymph nodes, and bone scintigram by 99mTc-HMDP showed an abnormal uptake in the swollen lymph nodes. Chemotherapy with CDDP (cisplatinum), VP-16 (etoposide), BLM (bleomycin), ADM (adriamycin) was not effective. Histopathological examination of a biopsy specimen revealed neuroblastoma. Another chemotherapy with CPM (cyclophosphamide), VCR (vincristine), ADM, DTIC (dacarbazine), CDDP, VP-16 was effective in decreasing the tumor size. Further high dose chemotherapy with CPM, ADM, CDDP, VP-16 combined with peripheral blood stem cell transplantation led to almost complete disappearance of the tumor and normalization of blood tumor markers (neuron specific enolase and immunosuppressive acidic protein). Retroperitoneal lymph node dissection demonstrated well-differentiated neuroblastoma in the excised tissue. Six months postoperatively, the tumor recurred in the pelvic cavity. Although chemotherapy and radiotherapy were given, he died of the disease 12 months postoperatively.
