Cytopathology of neuroblastoma, ganglioneuroblastoma and ganglioneuroma.

ABSTRACT

Four cases of neuroblastomas, two cases of ganglioneuroblastomas and one case of ganglioneuroma diagnosed by fine needle aspiration cytology (FNAC) are presented. Five tumors were in the retroperitoneum and two tumors occurred in the posterior mediastinum. Complete clinical history, physical examination, radiological investigation, laboratory parameters, cytological study of multiple slides aided with special stains and cell block preparation of aspirated material helped in diagnosis of these tumours. Cytohistopathological correlation was carried out from surgically resected specimens and from autopsy studies.
