A unique scrotal extratesticular epidermod cyst attached to the seminal vesicles
Bibliographic record
Abstract
A 46-year old man was admitted with a scrotal long standing painless mass. The work up included physical examination, alpha- fetoprotein (αFP) and beta-human chorionic gonadotropin (β-hCG) analyses, scrotal ultrasound (US), magnetic resonance imaging (MRI) and urethrocystoscopy. The patient underwent surgery. Surgical exploration revealed a separate mass between the testes extending superiorly with a thin stalk. It was dissected easily to the anterior aspect of the seminal vesicles and removed from the junction to the seminal vesicles. Pathology reported an epidermoid cyst. To our knowledge this is the first case of a scrotal extratesticular epidermoid cyst attached to the seminal vesicles. Epidermoid cysts can be seen anywhere in the midline from the cranium to the anus. Embriologically abnormal closure of neural groove or epithelial fusion lines is one of the theories that seem more probable. Genital epidermoid cysts are rare, painless and usually located in the testes. Up to date less than 10 case reports of extratesticular epidermoid cysts have been published. For those cases malignancy may not be ruled out, so the surgical removal was advocated.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
