Idiopathic pyostomatitis-pyodermatitis vegetans with nasal obstruction: A case report
Bibliographic record
Abstract
Pyostomatitis-pyodermatitis vegetans is an uncommon mucocutaneous dermatosis of unknown etiology. It presents as erythematous pustules that coalesce to form exudative vegetating plaques on the oral mucosa and/or skin. Diagnosis is largely based on clinical assessment, although histopathology should be used as supporting evidence. Pyostomatitis-pyodermatitis vegetans is associated with inflammatory bowel disease, liver dysfunction, and others. We report a case of a 48-year-old man who presented with erythematous eroded plaques involving his nares and upper lip. Investigations revealed a dense mixed inflammatory infiltrate and pronounced peripheral eosinophilia. Uniquely, the patient did not have inflammatory bowel disease or any other systemic condition. Systemic corticosteroids were helpful in clearing mucocutaneous lesions; however, this effect was only sustained at high doses. There are few reports of pyostomatitis-pyodermatitis vegetans in the medical literature. This case highlights key aspects of this extremely rare dermatosis, especially in otherwise healthy patients without inflammatory bowel 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.
