Rare case of paratesticular solitary fibrous tumour (lipomatous
Bibliographic record
Abstract
A 26-year-old male presented with an asymptomatic 6-cm leftparatesticular mass. Ultrasound and magnetic resonance imagingconfirmed this mass as extratesticular, likely a tumour arisingfrom the left spermatic cord. The mass demonstrated marked avidenhancement on post-contrast images, suggestive of a spermaticcord sarcoma. A left inguinal exploration was performed and grossexamination of the mass revealed a well-circumscribed tumourwith a discrete capsule separating it from the ipsilateral spermaticcord. The mass was resected without performing an orchiectomyand histology demonstrated a solitary fibrous tumour (lipomatoushemangiopericytoma), with minimal proliferative activity and negativemargins. The occurrence of a paratesticular solitary fibroustumour is exceedingly rare, with only a handful of case reports.We review the literature regarding this rare entity and discuss itsdiagnosis and management.

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.
