Syphilis proctitis: an uncommon presentation of <i>Treponema pallidum</i> mimicking malignancy
Bibliographic record
Abstract
Syphilis proctitis can mimic other conditions including inflammatory bowel disease, lymphogranuloma venereum and anal or rectal cancer. We describe a case of a man in his 60s presenting with a variety of anorectal symptoms, where the definitive diagnosis was challenging, leading to diagnostic delay and a protracted symptom course due to difficulties in identifying and treating this rare manifestation of syphilis. After extensive investigations and various treatments, a diagnosis of syphilis was made, and treatment resulted in complete resolution of symptoms within 1 month. This case highlights several issues for clinicians to consider during the diagnostic workup and management of patients presenting with anal symptoms and, in the context of a global upsurge in syphilis, serves as a reminder to remain vigilant to unusual and rare manifestations of infectious syphilis.

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.
