Hepatic Hodgkin Lymphoma Presenting as Solitary Hepatic Mass Following Other Iatrogenic Immunodeficiency-Associated Lymphoproliferative Disorder in a Patient With Rheumatoid Arthritis
Bibliographic record
Abstract
Lymphoproliferative disorders (LPDs) occur frequently in patients with rheumatoid arthritis (RA) under methotrexate treatment. Some LPDs spontaneously regressed after methotrexate discontinuation, but classic Hodgkin lymphoma (CHL)-type LPDs frequently relapse, and chemotherapy is usually required for the treatment. CHL usually spreads in contiguous lymph nodes and then infiltrates in organs at an advanced stage. Thus, hepatic Hodgkin lymphoma (HHL) without lymphadenopathy is extremely rare at diagnosis. We present a case of methotrexate-associated LPDs associated with systemic lymphadenopathy and hepatosplenic mass in a 71-year-old woman with RA under methotrexate treatment over 10 years. Although spontaneous remission occurred after methotrexate discontinuation, she developed HHL presenting as a solitary hepatic mass without lymphadenopathy 3 years after spontaneous regression. She received brentuximab vedotin (BV) combination chemotherapy without bleomycin to avoid pulmonary toxicity. Complete metabolic response was achieved after four courses of BV combination chemotherapy, and the activity of RA was kept to be in remission. Our case suggested that the recurrence lesions of LPDs may present at unexpected site, which is not coincide with the primary site, and BV combination chemotherapy is a promising regimen for limited-stage CHL-type LPDs in patients with RA owing to its anti-lymphoma effect on CHL-type LPDs and a possible targeted therapy for RA.

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.
