Reactive Lymphoid Hyperplasia of the Nasolacrimal Duct Presenting as Bloody Epiphora
Bibliographic record
Abstract
In Brief A 90-year-old man reported a 1-year history of tearing and irritation in the left eye. Ophthalmic examination was significant for bloody mucopurulent material expressed from the left nasolacrimal duct. The patient underwent external dacryocystorhinostomy with excision of a soft-tissue mass. Initial histopathologic examination of the specimen revealed an atypical lymphoid infiltrate. Subsequent immunohistochemistry suggested that the mass was reactive lymphoid hyperplasia. Lymphoid hyperplasia should be considered in the differential diagnosis of bloody epiphora, in addition to primary malignancy of the nasolacrimal duct, hematologic abnormalities, coagulopathies, vascular tumors, and giant papillary conjunctivitis. Reactive lymphoid hyperplasia should be added to primary malignancy, hematologic abnormalities, coagulopathies, vascular tumors, and giant papillary conjunctivitis as a cause of bloody epiphora.

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.
