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.
