Klippel-Trenaunay syndrome and gestational trophoblastic neoplasm

Abstract

Background: Klippel-Trenaunay syndrome is a non-heritable venous malformation with bone and soft tissue hypertrophy and cutaneous nevi.

Case characteristics: Neonate with Klippel Trenaunay syndrome born to a mother with past history of Gestational trophoblastic neoplasm.

Observation: Antenatally, a fetal vascular malformation was identified ultrasonologically at 29 weeks gestation. Acute myeloid leukemia was diagnosed in mother at 33 weeks gestation.

Message: A rare association of Klippel Trenaunay syndrome and gestational trophoblastic neoplasm with the possible role of either hyperglycosylated Human Chorionic Gonadotropin or chemotherapy as a link is highlighted.
