# Growing teratoma syndrome with extra pelvic metastasis and gliomatosis peritonei

## TL;DR

This paper discusses a rare medical condition where two rare tumors, growing teratoma syndrome and gliomatosis peritonei, occur together in a patient.

## Contribution

The novelty lies in the rare synchronous identification of growing teratoma syndrome and gliomatosis peritonei.

## Key findings

- Growing teratoma syndrome can occur after adjuvant chemotherapy for immature teratoma.
- Gliomatosis peritonei is often found alongside immature teratoma.
- Comprehensive imaging is critical for surveillance after immature teratoma treatment.

## Abstract

•Growing teratoma syndrome occurs when mature teratomas are discovered in patients who have previously received adjuvant chemotherapy for immature teratoma.•Gliomatosis peritonei is a rare condition often found alongside immature teratoma.•Synchronous identification of growing teratoma syndrome and gliomatosis peritonei has rarely been reported.•Comprehensive abdominopelvic imaging is critical to the surveillance protocol after treatment of immature teratoma to assess and appropriately treat this phenomenon.

Growing teratoma syndrome occurs when mature teratomas are discovered in patients who have previously received adjuvant chemotherapy for immature teratoma.

Gliomatosis peritonei is a rare condition often found alongside immature teratoma.

Synchronous identification of growing teratoma syndrome and gliomatosis peritonei has rarely been reported.

Comprehensive abdominopelvic imaging is critical to the surveillance protocol after treatment of immature teratoma to assess and appropriately treat this phenomenon.
