Solitary Lesions With Fibrosis and Increased IgG4+ Plasma Cells
Bibliographic record
Abstract
We assessed 6 cases acquired during routine surgical sign-out for IgG4-related disease (IRD) according to criteria from a recent consensus meeting. These cases fulfilled the morphologic criteria-that is, dense lymphoplasmacytic infiltrates, IgG4:IgG ratio greater than or equal to 0.4, and fibrosis (storiform in 4 cases-but were associated with malignancy or did not fulfill the criteria for a new site. These criteria include increased serum IgG4 (normal in the majority of IRD) and a response to glucocorticoids, which is not appropriate treatment for resectable lesions as in our cases. Until more is known about the natural history of the disease, we propose that the possibility of an early, localized, or forme fruste of IRD should be considered and that cases associated with malignancy should at least be documented. Although we acknowledge the value of the consensus criteria, their strict application may result in missed opportunities to study the disease.

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.
