# Hyperreactio Luteinalis: A Rare Phenomenon Complicating Gestational Trophoblastic Disease Presenting as Acute Abdomen in the Convalescence Period

## TL;DR

A rare gynecological condition called hydatidiform mole complicated by theca lutein cyst rupture presented as an acute abdomen in a young patient.

## Contribution

This case highlights the unusual presentation of hyperreactio luteinalis complicating gestational trophoblastic disease.

## Key findings

- A 17-year-old patient presented with acute abdomen due to ruptured theca lutein cysts following a molar pregnancy.
- Post-molar pregnancy outcomes are variable and understudied, with limited data from national databases and monocentric studies.

## Abstract

The hydatidiform mole is a rare gynaecological condition originating from trophoblastic cells, with an incidence of 1-3 per 1000 pregnancies. Theca lutein cysts (TLCs) and an invasive mole are rarely observed in association with a partial mole. This case describes an unusual case involving a 17-year-old primigravida at 11 weeks of gestation. She presented with abdominal pain and was diagnosed with a molar pregnancy with post-evacuation rupture of TLC, presenting as an acute abdomen, subsequently undergoing laparoscopy. Post-molar pregnancies exhibit a highly variable course, ranging from recurrent pregnancy loss and stillbirths to preterm deliveries and recurrent molar pregnancies. Few studies are available on obstetric outcomes after a molar pregnancy; most available data originate from national databases and monocentric research.
