Coexistence of Acute Cellular Rejection and Lymphoproliferative Disorder in a Lung Transplant Patient
Bibliographic record
Abstract
We report the case of a 37-year-old man who underwent bilateral lung transplantation for end-stage cystic fibrosis. Two months after his operation, a computed tomographic scan showed multifocal nodules throughout both lungs. Endobronchial biopsies revealed an Epstein-Barr virus-associated B-cell lymphoproliferation. Transbronchial biopsies revealed perivascular lymphoid infiltrates composed of predominantly small T lymphocytes. These perivascular infiltrates were retrospectively considered to be an acute cellular rejection rather than the periphery of the lymphoproliferative disorder. This opinion was based on several arguments: (a) a decrease in dosage of maintenance immunosuppression led to total regression of the lymphoproliferation but did not affect the perivascular lymphoid infiltrates; (b) the treatment of the acute cellular rejection temporarily induced the disappearance of the perivascular infiltrates; (c) the expression of Epstein-Barr virus was not detected in the perivascular infiltrates; and (d) on autopsy, performed 1 year later, severe obliterative bronchiolitis lesions were discovered, for which acute cellular rejection is the main risk factor. These observations point to the possibility that acute cellular rejection and an Epstein-Barr virus-associated lymphoproliferative disorder may coexist.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
