Malignant teratoma of the greater omentum

A 9-year-old girl with a malignant teratoma of the greater omentum is presented. The main presenting symptoms and signs were mild abdominal pain and a palpable abdominal mass. Exploratory laparotomy revealed a huge tumor occupying the peritoneal cavity and stemming exclusively from the greater omentum. This case represents an uncommon site of development of a malignant teratoma and may be the only one in the literature.
