Transitional Cell Carcinoma of the Urinary Bladder Metastatic to the Orbit
Bibliographic record
Abstract
We report a rare case of transitional cell carcinoma of the urinary bladder metastatic to the orbit, review the histopathology, and highlight characteristics of the few previously reported cases. A 68-year-old man with a remote history of transitional cell carcinoma of the urinary bladder presented with decreased visual acuity, afferent pupillary defect, and limited extraocular motility OS. Computed tomography scan of the orbits showed a diffuse infiltrate surrounding the left globe and optic nerve. Biopsy revealed metastatic transitional cell carcinoma. The patient expired one month later. With only seven cases previously reported, we conclude that transitional cell carcinoma of the urinary bladder rarely metastasizes to the orbit. When present, orbital metastases signify aggressive disease and a poor prognosis. Mean survival following orbital diagnosis is 2.2 months in the cases reported.

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.
