Abstract

Neurolastoma is one of the most common and highly malignant tumor of infancy and childhood, but the incidence of congenital neuroblastoma is rare. This case is of interest because extensive involvement of visceral organs by neuroblastoma presumably led to antenatal death. An autopsy, a well circumscribed tumor mass, measuring 5×4×3㎝ in size and 4gm in weight was found in left adrenal. The liver was enlarged and weighed 273gm. Other abnormalities were absent. Grossly the tumor was a solid, dark reddish, well circumscribed mass and homogeneous surface. The tumor nodules or masses were not seen in other visceral organs. Microscopically the tumor composed of round cells of neuroblasts with well formed rosettes and infiltrated the liver, right adrenal and lung, suspicious for the spleen and kidney.
