Esophageal Pancreatic Acinar Heterotopia: Premalignant or Benign
Bibliographic record
Abstract
Dysphagia, which refers to difficulty swallowing, can be caused by benign pathologies of the esophagus such as gastroesophageal reflux disease which is the most common cause. There are also malignant pathologies such as esophageal carcinoma which should be excluded during the initial clinical evaluation of a patient. Esophageal pancreatic acinar heterotopia (EPAH) is an exceedingly rare finding and an uncommon differential for dysphagia. A search of the literature yielded few previously reported cases. In general, the reported prevalence of pancreatic acinar heterotopia ranges from 16% to 24% in asymptomatic patients and 3% in patients with a known history of Barrett's esophagitis. It has been found in patients ranging from as young as 1 day old to an incidental autopsy finding. Here, we present a brief literature review and a case of a 57-year-old man with severe dysphagia who was discovered to have EPAH in the gastroesophageal junction, associated with active inflammation and focal metaplasia.

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.
