Isolated Pulse Granuloma in a Mesenteric Lymph Node: Unusual Nodal Manifestation Associated With Crohn Disease Complicated by Ileal Adenocarcinoma
Bibliographic record
Abstract
Abstract Pulse granuloma is an unusual inflammatory reaction to legumes. Pulse granulomas of the gastrointestinal tract are typically accompanied by significant mural damage due to ulceration, fistula, or perforation. We describe a solitary pulse granuloma in a mesenteric lymph node of a 74-year-old male patient with Crohn disease, who presented with an ileal adenocarcinoma, but without demonstrable fistula or perforation. To our knowledge, this is only the second reported example of Crohn disease associated with a pulse granuloma in a mesenteric node and also only the second example of a nodal location for any documented pulse granuloma. We postulate that mesenteric lymph node pulse granuloma may represent a unique and unusual type of morphology associated with Crohn disease.

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.
