Abstract
Neuroblastoma is the most common malignant tumor of
infancy and, after brain tumors, the most common malignant solid
tumors of childhood. Neuroblastoma accounts for 6 to 8 percent of
all childhood malignancies.
It originates from the neural crest. The tumor is fairly soft
and lobulated, with greyish to pink color and with areas of Haemorrhage
and necrosis.
It is one of small round cell tumors of childhood which can
be seen to form themselves into rosettes in well differentiated
disease.
Neuroblastoma commonly presents as a mass anywhere along
the sympathetic chain from the head to the pelvis. Intractable
watery diarrhea, hypertension are other forms of presentation.
Being a highly metastatizing tumor ,the liver suffers the brunt of
metastatic dissemination.
