Pediatric gastric mesothelial cyst presenting with abdominal distention and pain: A case report
Bibliographic record
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 reported in children. Surgical excision remains definitive, with no recurrence at 6-month follow-up. CONCLUSION: This case emphasizes the need to consider rare gastric cysts in pediatric abdominal masses and the role of histopathology in diagnosis.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
