Placental teratoma: Case report and review of the literature
Fecha
2014Abstract
Objective: Placental teratoma is an infrequent
benign tumour and there are only a few reports
in the world, none of them in Colombia. A
case is presented with a review of the literature
regarding prenatal and histopathology diagnosis,
and prognosis of placental teratoma in pregnancy.
Materials and methods: We present the case
of a 19 year-old patient in week 32 of gestation
who came to the Obstetric Unit at the Hospital
Universitario San Rafael, a private Level IV
general hospital in Bogotá, Colombia. The patient
had a prenatal ultrasound finding of an image
of heterogeneous echogenicity in the amniotic
cavity. An oval-shaped solid-appearing 5-cm mass was found on the fetal side of the placenta. The
histopathology showed findings consistent with
placental teratoma. A review of the literature was
conducted in the PubMed, Lilacs, SciELO, Ovid,
and ScienceDirect databases.
Results: Of 10,523 titles found, 23 related to
placental teratoma were selected. They were all
case reports. The diagnosis of placental teratoma is
based on prenatal diagnosis and histopathology; the
latter shows mature tissues of the three germinal
layers without defined organization. It has a good
obstetrical prognosis and does not appear to
increase the risk of foetal malformations.
Conclusion: Placental teratoma is a tumor of
infrequent ocurrence, usually of benign nature.
Key words: Placenta, teratoma, neoplasia
