Abstract:
Being of embryonal tissue origin, the teratomas are rare in adults,
typically occurring either in the gonads or in the sacrococcygeal region
in infancy and childhood. We present a case of a teratoma in the lesser
sac of an adult female managed by en-bloc resection with the
infiltrating stomach segment.
Clinical message :
Retroperitoneal teratomas are rare in adults and, present challenging
surgical management as they usually infiltrate into adjacent
retroperitoneal organs. Most are benign but the malignant mature cystic
teratomas have the potential to metastasize to retroperitoneal lymph
nodes and lung parenchyma. The definitive treatment of these neoplasms
is surgical resection.
