Uncommon testicular metastasis of a primary neuroendocrine tumour of the lung
Bibliographic record
Abstract
A 52-year-old male presented with an asymptomatic palpable mass of the right testicle. Ultrasound confirmed the presence of a testicular tumour and a hemicastration was performed. None of the testis cancer-related tumour markers were elevated and histological findings revealed a neuroendocrine carcinoma, possibly a metastasis from another primary site. The radiological findings showed a lesion in the lung, and a positron emission tomography (PET)-scan was made. The PET scan revealed an increased fluorodeoxyglucose (FDG) uptake in the pulmonary lesion. It also showed lymphatic and hepatic metastases. The patient had no complaints besides a palpable testicular mass and was diagnosed with a cT1aN3M1b neuroendocrine carcinoma of the lower left field of the lung, stage IV. To our knowledge, the presentation of testicular metastasis of a neuroendocrine carcinoma of the lung has not been described in the literature. No curative options were available and the patient is being treated with salvage chemotherapy.

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.
