Abstract
We report detailed histological and molecular characteristics of four post transplant lymphoproliferative disorders (PTLD) presenting in the skin of renal transplant patients, and their clinical outcome. Three had B-cell lymphomas (cases 1-3), and one had a T-cell lymphoma (case 4). All B-cell lymphomas showed Epstein-Barr virus (EBV) by immunohistochemistry (IHC) or in situ hybridization (ISH). Cases 1 and 2 were large cell lymphomas, and case 3 a plasmacytoma. Case 1 showed light chain restriction and heavy chain gene rearrangement by polymerase chain reaction (PCR). The patient was then diagnosed with an abdominal lymphoma and died of sepsis. Case 2 had no recoverable DNA. Case 3 had a plasmacytoma that showed monoclonal light chain restriction on IHC and an oligoclonal heavy chain rearrangement by PCR. In cases 2 and 3, the lesions regressed following reduction of immunosuppression, and died 1.5 and 8 years later from unrelated medical causes. Case 4 was a CD 30+ anaplastic large T-cell lymphoma with no EBV detected by IHC, ISH and PCR, and died of heart failure 2 years later. Cutaneous manifestations of PTLD are rare, show wide array of clinical and pathological features, and generally have a favorable prognosis. EBV appears to be associated only with B-cell cutaneous lymphomas.

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 it
