[Primary peritoneal yolk sac tumour. A case report].
Yolk sac tumours are rare germinal neoplasms that often arise in ovary and testis. Extragonadal localisations such as mediastinum, retroperitoneum, brain and vagina are uncommon. Primary intraperitoneal tumours are exceedingly rare. We report a case of a 16-year-old girl who underwent laparotomy for an acute abdominal pain and circulatory dysfunction. Abdominal exploration disclosed a large mass involving mesentery of the transverse colon associated to three hepatic nodules and abundant peritoneal bleeding. Segmental hepatic resection was performed and the mesenteric mass was removed. Microscopic examination of the pathologic specimen concluded to a yolk sac tumour. Patient underwent intensive chemotherapy; she's free of disease 2 years after diagnosis. Through this case, clinicopathologic features of this rare neoplasm will be discussed.
