A ten-year review revealed a similarity in the incidence of teratoma in relation to other childhood tumors in Malaysian as compared with Caucasian children. The most common sites of origin were the sacropcoccygeal, gonadal, and retroperitoneal areas. The reason for the high incidence of retroperitoneal tumor in our series as compared with other countries is not clear. Late presentation and poor followup are associated with poor prognosis.
A review of 20 cases of neuroblastoma at the University Hospital, Kuala Lumpur from 1967 to 1980 reveals six infants aged 2 to 13 months with stage IV·S disease, associated with an unusually good prognosis. Four of the six patients presented with hepatomegaly, one had skin nodules and another paresis of the lower limbs. The primary tumour was located infra-diaphragmatically in all cases, four had disease in the bone marrow but none had radiological evidence of bone involvement. Although not systematic, with limited treatment of low dose radiation and mild chemotherapy, four patients are alive and well, one absconded and one died of septicaemia. It is important to define this special category as an unexpectedly good survival is possible with minimal therapy. Death is more likely to result from over-zealous treatment than from the disease itself.
