Placental Giant Chorangioma: A Rare Case Report with Favorable Outcome

Abstract

Chorangiomas are benign non trophoblastic vascular neoplasm arising from primitive chorionic mesenchyme. It is
the most frequent placental tumor occurring in 1% of pregnancies. Giant chorangioma(>5 cms) exemplifies adverse
fetal and maternal outcomes. Chorangiomas need to be differentiated from chorangiosis, chorangiomatosis,
inflammatory myofibroblastic tumor, leiomyomas, placental infarcts and chorangiocarcinomas. USG is the
gold standard for diagnosis of chorangioma. Color Doppler is benificial in differentiation of chorangioma from
degenerated uterine leiomyoma or associated other placental tumors. Therapeutic interventions of chorangioma
is controversial like draining excessive amniotic fluid or surgical intervention like laser coagulation and interstitial
laser therapy. All placentas need to be examined histopathologically for confirmation of diagnosis and to
differentiate from other tumors.
