Trichodysplasia Spinulosa: Rare Presentation of Polyomavirus Infection in Immunocompromised Patients
Bibliographic record
Abstract
BACKGROUND: Trichodysplasia spinulosa (TS) is a rare, striking, folliculocentric papular eruption seen exclusively in immunosuppressed patients. The eruption can be disfiguring, associated with leonine faces and alopecia. TS is caused by a polyomavirus, identified as trichodysplasia spinulosa polyomavirus (TSPyV). Few reports exist in the literature, and support for treatment options is sparse. METHOD AND RESULTS: We report a patient with TS with underlying lupus nephropathy and renal transplant-associated immunosuppression. Diagnosis was confirmed by biopsy and pathognomonic histologic findings in the context of her extensive, spiculated monomorphous papules. With a biopsy-confirmed diagnosis, oral valganciclovir was prescribed, and the patient showed marked skin texture improvement and hair regrowth. CONCLUSION: The continued reporting of cases of TS will improve clinical identification of this condition and provide better information regarding treatment and long-term consequences.

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.
