RESUMO
Los tumores malignos de ovario son raros en la edad pediátrica y pueden originarse de los componentes del tejido ovárico; el tumor más frecuente es el de células germinales. La variedad de tumores del estroma incluye los tumores de células de la granulosa (teca y los tumores de células de Sertoli-Leydig); este grupo de tumores son raros; sin embargo, son propensos a presentarse con pubertad precoz. Se presentan tres casos clínicos de pacientes que cursaron con manifestaciones clínicas de pubertad precoz y tumoración abdominal. Se estableció un protocolo de estudio para su abordaje y, finalmente, se realizó resección quirúrgica, con evolución satisfactoria.
Malignant ovarian tumors are rare in children. They may originate from components of the ovarian tissue; the germ cell tumor is the most common. The variety of stromal tumors include granulosa cell tumors (theca and Sertoli-Leydig cell tumors); this group of tumors is rare but they are likely to present with precocious puberty. We report three cases of patients with clinical manifestations of an abdominal tumor in association with precocious puberty; we also describe the way they were approached, until final surgical resection. We had excellent results.
RESUMO
Duplications of the gastrointestinal (GI) tract are rare. Only 5% of them are rectal and there are very few reports of rectal prolapse (RP) caused by a duplication. An 11 month-old female presented with a RP caused by a blind-ended anterior tubular colorectal duplication. The duplication was successfully opened and connected to the normal rectum without complications. Although infrequent, a rectal duplication should be considered in the differential diagnosis of RP.
