Immature extragastric teratoma of infancy: a rare tumour with review of the literature.

A full term otherwise healthy, 4-months-old male infant presented with progressive distension of abdomen from 2 months. The clinical examination showed shifting dullness only but no definite lump palpable. The abdominal radiography revealed calcification in right hypochondrium. Serum α-feto protein (AFP), neuron specific enolase, β human chorionic gonadotrophin and urinary vanillymandelic acid (VMA) were appropriate for age-range. Contrast enhanced abdominal CT showed predominantly multicystic lesion in right hypochondrium with central solid component and calcification, but no definite organ of origin determined. The exploratory laparotomy showed extra gastric multilobulated cystic mass sized 23×15×8 cm lesion arising from the lesser curvature of body of stomach. The tumour was feeding through short pedicle based on left gastric artery. There was no infiltration to adjacent areas. Histopathology of excised specimen showed immature teratoma. The child was discharged with appropriate advice and had no recurrence in 1 year of follow-up.
