Solitary prostatic cancer metastasis to the testis: A case report and lessons to learn
Bibliographic record
Abstract
Prostate cancer (Pca) is a complex disease. Several case series and reports have described the spread of Pca to unusual organs, like esophagus, eye and periureteric fat causing ureteropelvic junction obstruction. Spread of Pca to the testis has been reported in few case reports, however Pca was always firstly diagnosed in all published cases and testicular spread of cancer has been diagnosed during follow up of the patients. This case is unique in that, the patient initially presented with a testicular mass and histologic examination after orchiectomy allowed to diagnose prostatic cancer. This patient was 81 years old and he never had PSA screening by his family doctor. PSA was not even done initially by us considering his age and the presentation with testicular mass. This case may impact clinical practice in several ways: 1) considering Pca always in the differential diagnosis of any disease of an adult man, regardless of its presentation because we did not do that at initial patient evaluation and PSA was only measured after orchiectomy when pathology demonstrated metastatic Pca; 2) suggesting standard orchiectomy with epididemectomy for surgical castration instead of the current surgical technique of subcapsular/subepididymal orchiectomy, because our patient had cancer involving his epididymis as well; 3) suggesting to include PSMA as a part of preoperative staging for high risk Pca patients, in consideration that PSMA is proving to be a promising new imaging technique that can help diagnosing metastatic Pca in unusual locations.

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.
