Benign Multicystic Peritoneal Mesothelioma Presenting as Appendiceal Abscess: A Diagnostic and Therapeutic Challenge
Bibliographic record
Abstract
Primary peritoneal tumors are rarely encountered and their management is usually challenging for the clinicians. Especially when the patients with advanced peritoneal malignancy present as surgical emergencies, usually with symptoms of obstruction, perforation or gross space-occupying lesions, the on-call surgical team has to weigh the pros and cons of urgent versus delayed treatment and plans a safe and simultaneously oncologically beneficial therapeutic approach. Herein, we present a case of a Caucasian man who was referred as suspected complicated appendicitis by his primary care physician, with the final diagnosis being benign multicystic mesothelioma. We describe the challenges of the clinical decision making for the emergency general surgeon and relevant diagnostic and therapeutic pitfalls, which can be potentially minimized by early liaison with tertiary units specializing in the treatment of disseminated peritoneal malignancy.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
