Mature gastric teratoma in a female infant associated with malrotation: A case report

Gastric teratoma is a extremely infrequent tumor and accounts for less than 1% of all teratomas among children population with male predominance. Case history: Herewith is described a case of mature gastric teratoma in a three months-old female infant associated with malrotation, hypotonia, torticollis and fusion of labia minoria. Due to the abdominal distension, the child was admitted to the Paediatric Surgery Department. On physical examination, a large lump was palpable, and laboratory findings were normal. Computed tomography (CT) showed a major heterogeneous solid formation within the right hemi-abdomen, extending to pelvis and crossing the midline. The infant underwent surgery and complete excision of tumor originating from lesser curvature of the stomach was made. Tumor was weighing 600 gr and was 10 x 14 x 8 cm large. The histopathological examination finding pointed to mature gastric teratoma. The post-operative course and further follow-up were eventless. Conclusion: As soon as the diagnosis is made, the surgery is of paramount importance, especially in cases of immature teratomas, where malignant alteration is possible.
