A case of probable drug-induced psoriasis to dapagliflozin
Bibliographic record
Abstract
Exposure to certain drugs can trigger new-onset psoriasis or flaring of existing psoriatic disease. The clinical presentation of drug-induced psoriasis can vary, and although there are features suggestive of drug-induced psoriasis, there are currently no standardized criteria to differentiate it from conventional psoriasis. Patients may present with localized psoriasiform plaques, or variants such as palmoplantar, nail disease, or widespread erythroderma. Histopathology of drug-induced psoriasis can also be indistinguishable from conventional psoriasis but features suggestive of drug-induced include lack of suprapapillary epidermal thinning, a limited number of Munro microabscesses, and the presence of eosinophils and/or a lichenoid reaction pattern. We report a case of suspected drug-induced psoriasis due to dapagliflozin (Farxiga) in a 76-year-old man. Evidence indicating this to be a probable drug-induced reaction includes the sudden onset of symptoms; atypical pathology with the presence of eosinophils; and clearance of the lesions upon discontinuation of the suspected causative drug.

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.
