RESUMEN
Presentamos el caso clínico de una paciente de 18 años sin antecedentes a destacar. Cursando las 30 semanas de embarazo se constata una tumoración abdominal que requirió tratamiento quirúrgico y se diagnosticó un teratoma inmaduro grado 3, asociado a gliomatosis peritoneal. Se realizó una cesárea al término y se instauró el tratamiento con quimioterapia presentando una recidiva a los siete meses que requirió tratamiento quirúrgico conservador y nuevo plan de quimioterapia estando actualmente libre de enfermedad y en seguimiento. Lo infrecuente de esta patología y asociada a embarazo, motivó su comunicación.
We report the case of a healthy 18-year old patient with adnexal mass diagnosed by her 30th week of pregnancy. It required surgical treatment and a grade 3 immature teratoma associated with peritoneal gliomatosis was diagnosed. A cesarean section was performed at term and subsequently chemotherapy was established. The patient presented a recurrence seven months later, which required fertility-sparing surgery and a new chemotherapy plan. The patient is currently disease-free and under surveillance. The infrequency of this disease and associated with pregnancy, led to their communication.
