Abstract
Phenytoin induces lymphoid proliferation, resulting in complications that can range from tissue hyperplasia to lymphoma. Some of the complications resolve spontaneously after drug discontinuation. This report describes for the first time a case of dysphagia with lack of velopharyngeal coordination and nasopharyngeal reflux combined with massive palatine tonsillar hypertrophy. The condition did not develop before phenytoin administration, was induced by phenytoin, and spontaneously resolved upon drug discontinuation. The patient was referred for a video-fluoroscopic swallowing study owing to a recurring nasal reflux of foods that had developed since phenytoin administration. The video-fluoroscopic swallowing study revealed incidentally that the large bilateral elongated masses extended downward into the larynx and disturbed velar elevation. This finding was confirmed by computed tomography of the neck, which showed that palatine tonsillar hypertrophy disturbed the laryngopharynx on both sides. The symptoms (sleep apnea and nasal reflux) and the abnormal imaging findings disappeared without surgery approximately 1 month after drug discontinuation. This case suggests that dysphagia related to phenytoin-induced lymphoid hypertrophy may be treated by phenytoin discontinuation followed by a sufficient amount of time to allow symptom resolution rather than by prompt surgery.

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.
