Gastric teratoma-unusual cause of neonatal obstructive jaundice: a case report.

The gastric teratoma is a very rare tumour that usually presents as an abdominal mass, gastrointestinal bleeding with/without features of gastric outlet obstruction. We report a rare case of immature gastric teratoma in a two months old female child who presented with abdominal lump and jaundice. The presentation was a diagnostic challenge and a dilemma, added by the fine needle aspiration cytology (FNAC) suggestive of small round cell tumor, favouring diagnosis of Wilms tumor over Neuroblastoma. Intra-operatively the tumor was found compressing upon the common bile duct (CBD). Final histopathological examination (HPE) revealed immature gastric teratoma Grade III. We wish to highlight this unusual presentation of gastric teratoma manifesting with obstructive jaundice and fallacy of FNAC in the diagnosis of teratomas.
