A secondary syphilis rash with scaly target lesions
Bibliographic record
Abstract
A 40-year-old man reported a 5-day history of fever and malaise, followed by a pruritic generalized rash. He had well-demarcated erythematous papules and plaques with scaling. The patient was diagnosed with secondary syphilis. The skin biopsy showed a psoriasiform lichenoid dermatitis with plasma cells. The anti-T. pallidum antibody confirmed the presence of spirochetes. He was also found to be hepatitis C virus and human immunodeficiency virus positive. The characteristic rash of secondary syphilis may appear as maculopapular, evolving initially from macules to small reddish-brown papules with minor scaling later. When the scaling is prominent, lesions can be difficult to differentiate from guttate psoriasis. Typical target lesions are most often associated with erythema multiforme, but they can rarely occur in secondary and congenital syphilis. Syphilis should be suspected in high-risk patients presenting a variety of atypical syndromes such as neurologic symptoms, uveitis or cholestatic hepatitis, especially if palmoplantar lesions are present.

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.
