# A complicated case of refractory multiple drug-resistant peritoneal dialysis-associated peritonitis due to teratoma

## TL;DR

A patient with drug-resistant peritoneal dialysis infection was found to have a teratoma, which was successfully treated with surgery and antibiotics.

## Contribution

This case highlights a rare cause of refractory peritonitis in dialysis patients and its successful management.

## Key findings

- The infection was caused by a teratoma, not a typical bacterial pathogen.
- Treatment involved drainage, targeted antibiotics, and teratoma excision.
- The patient transitioned to hemodialysis after successful intervention.

## Abstract

Peritoneal dialysis-associated peritonitis is a leading cause of treatment discontinuation and mortality among peritoneal dialysis patients. The presence of multidrug-resistant organisms further complicates management, particularly in patients with complex intra-abdominal conditions. This paper presents a complicated case of refractory multidrug-resistant peritoneal dialysis-associated peritonitis, which was ultimately diagnosed as being caused by a teratoma. Following adequate drainage and the administration of sensitive antibiotics, the patient successfully underwent teratoma excision and transitioned to hemodialysis.
