Abstract
Castleman disease (CD) is an uncommon lymphoproliferative disorderand is especially rare in the retroperitoneum or perirenalarea. We report the case of a 42-year-old woman in whom we foundon routine physical examination a mass localized in the rightabdomen without clinically important constitutional symptoms for30 days. Abdominal ultrasound, magnetic resonance images andcomputed tomography scans revealed a solid mass localized justbelow the right kidney in the retroperitoneum. The patient subsequentlyunderwent an exploratory laparotomy. Pathological examinationrevealed a right retroperitoneal mass of CD (hyaline vasculartype). The patient completely recovered after surgery. Castlemandisease is commonly misdiagnosed as malignant lymphoma,lymphadenitis or ectopic thymoma. So far, its diagnosis is mainlyachieved via histopathological examination of surgically obtainedtissue. After removal of the lesion, local CD has a good prognosis.La maladie de Castleman est un trouble lymphoprolifératif rare,surtout dans les régions rétropéritonéale ou périrénale. Nousdécrivons le cas d'une femme de 42 ans chez qui un examenphysique de routine a révélé la présence d'une masse localiséeau côté droit de l'abdomen sans que cette patiente n'affiche desymptômes constitutionnels d'importance clinique pendant 30 jours.Des images obtenues par échographie abdominale, par IRM et partomodensitométrie ont révélé la présence d'une masse solide situéejuste en dessous du rein droit dans la région rétropéritonéale. Lapatiente a ensuite subi une laparotomie exploratoire. L'examend'histopathologie a révélé une masse rétropéritonéale droite caractéristiquede la maladie de Castleman dans sa forme hyaline vasculaire.La patiente s'est complètement rétablie après l'intervention.Au moment du diagnostic, la maladie de Castleman est souventconfondue avec un lymphome malin, une lymphadénite ou un thymomeectopique. Jusqu'à présent, le diagnostic de cette maladieest posé principalement sur la base d'un examen histopathologiquede tissus prélevés par chirurgie. Après ablation de la masse, lepronostic lié à la maladie de Castleman est favorable.

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.
