An Unusual Presentation of Cronkhite–Canada Syndrome With Hypothyroidism
Bibliographic record
Abstract
Background: Cronkhite–Canada syndrome (CCS) is a rare, nonhereditary gastrointestinal polyposis characterized by diffuse polyps, hyperpigmentation, onychodystrophy, and alopecia. Hypothyroidism has been infrequently reported in association with CCS. Case Presentation: A Caucasian male in his late 70s presented with dysgeusia, asthenia, and significant weight loss, initially diagnosed with Crohn’s disease. Physical examination showed onychodystrophy, hyperpigmentation, and leg edema. Laboratory tests revealed severe hypothyroidism, hypoalbuminemia, and elevated serum IgG‐4 levels. Upper and lower endoscopies showed diffuse gastric and colonic polyposis with chronic inflammation, eosinophilic infiltration, and hyperplastic changes. Diagnosis of CCS was confirmed. Treatment included corticosteroids and thyroid hormone replacement. Conclusion: This case highlights CCS diagnostic challenges, particularly when misdiagnosed as inflammatory bowel disease. The coexistence of hypothyroidism and elevated serum IgG‐4 levels suggests a possible autoimmune component. Early recognition of this rare syndrome is essential for appropriate management.

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.
