Borderline serous papillary tumour of the testis: a case report and review of the literature.
Bibliographic record
Abstract
Borderline serous tumour of the testis and paratestis is an uncommon entity. We report a case of borderline serous tumour of a 59-year-old male, who presented with a right testicular swelling which was clinically suspicious of carcinoma. Radical orchidectomy was performed and a cystic lesion was identified in the testis. Macroscopically the tumour was composed of a unilocular cyst with excrescences in the inner surface. The histological features were identical to the ovarian counterpart of borderline serous papillary tumour. The excrescences were formed by stratified columnar epithelium, which exhibited mild nuclear pleomorphism and mitotic activity, with a fibrovascular core and scattered psammoma bodies. There was no lymphovascular or stromal invasion. The lesion was surrounded by a dense fibrous wall. On immunohistochemistry, the lining epithelial cells expressed cytokeratin AE1/AE3 but not carcinoembryonic antigen or calretinin. Following the removal of the tumour, the patient was followed up and no recurrence or metastasis has occurred to date. This case highlights the need for clinicians and pathologists to be aware of this rare entity and to develop the best approach for patient management.

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.
