Drug-Induced Lichenoid Dermatitis with Histopathologic Features of Mycosis Fungoides in a Patient with Psoriasis
Bibliographic record
Abstract
BACKGROUND: With recent advancements in the understanding of psoriasis, treatment has evolved toward more targeted therapy in the form of biologics. Although generally safe and well tolerated, various adverse reactions may occur with the use of biologics. OBJECTIVES: The objective of this article is to present a case of a biologic-induced drug eruption initially presenting with histopathologic features of mycosis fungoides (MF). METHODS AND RESULTS: A 47-year-old male presented with an extensive erythematous macular eruption approximately 14 hours after a single dose of etanercept. Histopathology initially revealed a lichenoid dermatitis with features of MF, but immunohistopathology later refuted the presence of MF. CONCLUSIONS: It is important for clinicians to be aware that adverse cutaneous reactions with biologic therapy may initially present with histopathologic features of MF.

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.
