Human Herpes Virus-8-Associated Multicentric Castleman's Disease in a Human Immunodeficiency Virus-Positive Patient with a Previous History of Kaposi's Sarcoma
Bibliographic record
Abstract
Human herpes virus-8 (HHV-8)-associated Castleman's disease (CD) is a rare non-cancerous B-cell lymphoproliferative disorder in human immunodeficiency virus (HIV)-positive patients. We report a case of HHV-8-associated CD in an HIV-positive patient with a previous history of Kaposi's sarcoma (KS). The patient presented with progressive splenomegaly and diffuse lymphadenopathy, which can be seen in multicentric CD, KS, and HIV-associated lymphoma. There are no reliable clinical or imaging features to differentiate these diseases. Lymph node biopsy confirmed HHV-8-associated CD and excluded KS and lymphoma. Due to differences in treatment options and prognosis between the three etiologies, it is important for radiologists to include HHV-8-associated CD in the differential diagnosis when encountering HIV-positive patients that present with diffuse lymphadenopathy.

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.
