A Case of Cronkhite-Canada Syndrome Presenting with Hematochezia
Bibliographic record
Abstract
Cronkhite-Canada syndrome (CCS) is a rare, non-familial hamartomatous polyposis syndrome characterized by multiple polyps in the entire gastrointestinal tract, nail dystrophy, skin pigmentation, and systemic alopecia. The clinical symptoms of this syndrome include diarrhea, abdominal pain, and alopecia often accompanied by taste disturbances, hypoalbuminemia, recurrent infections, nutritional absorption disturbances, heart failure, and gastrointestinal bleeding. We report a patient with CCS who was admitted complaining of hematochezia, melena, and a 1 month history of diarrhea, nail changes, taste disturbances, and alopecia. Upper endoscopy, colonoscopy, and capsule endoscopy were performed and showed numerous polyps in the stomach, small intestine, and large intestine. Histological sections of these polyps showed edematous stroma and cystically dilated foveolar epithelium, which was consistent with CCS. We diagnosed CCS based on the clinical symptoms and the histological findings of the polyps found via endoscopy. We report on this case and review this syndrome.

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.
