A Rare Case of Castleman Disease Presenting as an Ovarian Tumor
Bibliographic record
Abstract
Castleman disease (CD) is a rare lymphoproliferative disorder of unknown etiology. Its most common location is the mediastinum, but many other sites have been reported. We report a case of primary CD of the ovary, a rare localization with only 2 cases including the present case described in the world literature to date. A 58-yr-old woman who initially presented with abdominal pain underwent computed tomography scan which showed bilateral well-circumscribed solid adnexal masses. Because an ovarian bilateral tumor was suspected the patient was treated with a hysterectomy and bilateral salpingo-oophorectomy and the histopathologic examination confirmed the diagnosis of CD hyaline-vascular type of the right ovary associated with a contralateral fibroma. Three years after surgery the patient is alive and well and shows no signs of recurrent disease. The occurrence of this rare presentation of CD is the subject of this report. The problems of differential diagnosis with the most frequent lesions of the female pelvis are also discussed.

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.
