Benign teratoma of the lesser omentum--a case report.

ABSTRACT

Teratomas of the lesser omentum are extremely rare and all cases reported in the literature have been benign teratomas with mature tissue elements. A case of teratoma, which behaved in benign fashion in spite of immature elements in a 16-year-old male, is reported. The patient remained free of disease 7 years after surgical resection of the tumour.
