Pediatric gastric mesothelial cyst presenting with abdominal distention and pain: A case report.

ABSTRACT:

Introduction

Mesothelial gastric cysts are exceedingly rare in pediatric patients, often mimicking mesenteric or duplication cysts. This case highlights diagnostic challenges and underscores the importance of histopathological confirmation.

Presentation of case

A 3-year-old boy presented with 6 months of progressive abdominal distention and intermittent pain. Imaging revealed a 12 × 10 cm unilocular cystic mass, initially suspected to be mesenteric. Intraoperatively, the cyst originated from the gastric wall. Complete excision and histopathology confirmed a mesothelial cyst. Histopathology showed a unilocular cyst lined by flattened mesothelial cells resting on a fibro-collagenous wall, without atypia or mitoses.

Discussion

Gastric mesothelial cysts are rarely reporte
