Spontaneous Retroperitoneal Hemorrhage in a Patient with Prolymphocytic Transformation of Chronic Lymphocytic Leukemia
Bibliographic record
Abstract
Prolymphocytic transformation of chronic lymphocytic leukemia is a rare but recognized entity. We present the case of a 76-year-old gentleman with a previous diagnosis of chronic lymphocytic leukemia who presented with fatigue, fever, and a white blood cell count of 500 000 with prolymphocytes on peripheral blood examination. Chlorambucil and dexamethasone were initiated. He developed progressive anemia during his admission with no clear cause on initial CT examination. Bilateral hip pain began several days later and he was unfortunately diagnosed with a large spontaneous retroperitoneal hemorrhage postmortem. This condition is rare and generally occurs in those receiving therapeutic anticoagulation or dialysis, with known bleeding disorders or vascular malformation, none of which were present in our patient. Pathology revealed marked leukemoid engorgement of the vessels of many organs with prolymphocytes. We discuss the potential etiologies and relationships between these critical diagnoses.

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.
