S3591 Unravelling the Enigma: Cronkhite – Canada Syndrome
Bibliographic record
Abstract
Introduction: Cronkhite–Canada syndrome (CCS) is a rare condition characterized by diffuse gastrointestinal polyposis, diarrhea, weight loss, ectodermal changes which were observed in our case of a 79-year-old man. The diagnosis was confirmed through endoscopic and histological examination. Treatment included corticosteroids which resulted in diarrhea improvement. CCS is challenging to diagnose due to its rarity, unclear etiology, and limited treatment options. Case Description/Methods: Case Description: A 79-year-old man presented with chronic watery diarrhea (up to 20 episodes daily) and a 15-pound weight loss over 6 to 8 weeks, dystrophic changes of fingernails and hair loss. There was no recent antibiotic use, travel, or unusual ingestions, no sick contacts. Physical examination revealed dry skin, and cracking and peeling fingernails. Laboratory studies showed negative stool tests for infections, normal stool pancreatic elastase, elevated erythrocyte sedimentation rate and C-reactive protein, with hypoalbuminemia. Liver and kidney panels were normal except for total bilirubin. Endoscopy revealed diffuse erythematous and polypoid mucosa in the stomach and colon, with biopsies showing acute and chronic inflammation and eosinophilic infiltration. A diagnosis of Cronkhite–Canada syndrome (CCS) was confirmed by a second pathology review. The patient was treated with 9 mg of oral Budesonide, resulting in complete resolution of diarrhea, and was referred for nutritional evaluation. Methods: This retrospective case report was based on the patient’s medical records, including clinical presentation, physical examination, laboratory findings, and endoscopic results. Histopathological analysis of gastrointestinal biopsies and an external second opinion confirmed the diagnosis of CCS. Discussion: Cronkhite–Canada syndrome (CCS) is a rare condition characterized by diffuse gastrointestinal polyposis, diarrhea, weight loss, and ectodermal changes with hypoalbuminemia, which was observed in our case. With only about 450 cases reported, its etiology remains unknown. Diagnosis relies on clinical history, physical examination, endoscopic findings, and histology. Therapeutic options are limited, with glucocorticoids being the primary treatment despite uncertain efficacy. This case underscores the necessity of a high index of suspicion and comprehensive evaluation for effective diagnosis and management of CCS. Further documentation and study are essential to advance understanding and treatment of this rare syndrome (see Figure 1).Figure 1.: Gastric antrum.

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.
