Granular cell tumour of the ureter: first case reported
Bibliographic record
Abstract
A 33-year-old woman presented with nonspecific, colicky pain ofthe left lower abdomen. Computed tomography (CT) revealed a2-cm mass engulfing the mid–left ureter. Ureteroscopy and biopsyrevealed normal mucosa, and CT-guided biopsy of the masswas nondiagnostic. The patient underwent laparoscopic exploration.A frozen section taken from the mass revealed a granularcell tumour. We excised the whole involved portion of the ureterand performed end-to-end ureteroureteral anastamosis. The postoperativecourse was uneventful. Examination of a segment ofresected ureter revealed a granular cell tumour diffusely infiltratingthe wall of the ureter. There were no features suggestinga malignant phenotype. On follow-up, the patient was found tohave developed a stricture at the anastomotic area, which wassuccessfully treated with balloon dilatation. To our knowledge,this is the first reported case of a granular cell tumour involvingthe ureter.Une patiente de 33 ans présente des douleurs non spécifiquesau quadrant inférieur gauche de l’abdomen rappelant des coliques.Une TDM révèle une masse de 2 cm englobant la portioncentrale de l’uretère gauche. Une urétéroscopie et une biopsiene révèlent aucune anomalie de la muqueuse, et une biopsiede la masse guidée par TDM n’a pas permis de poser un diagnostic.La patiente a subi un examen par laparoscopie. Des fragmentscongelés de la masse ont révélé une tumeur à cellules granuleuses.Une excision de la partie atteinte de l’uretère a été suivied’une anastomose urétéro-urétérale. Aucune complication postopératoiren’a été signalée. Le rapport final de pathologie faitétat d’une tumeur à cellules granuleuses s’étant infiltrée de façondiffuse dans la paroi de l’uretère. Aucune observation ne porteà croire à la présence d’un phénotype malin. Au suivi, la patienteprésentait une sténose de la région de l’anastomose qu’on a putraiter efficacement par dilatation par ballonnet. À notre connaissance,il s’agit du premier cas de tumeur à cellules granuleusestouchant l’uretère.

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.
