Abstract
Squamous metaplasia in a pleomorphic adenoma (PA) has been reported, but rarely has it been documented as being extensive enough to cause significant misdiagnosis. We present a case of a 37-year-old man presenting with a 1.7-cm minor salivary gland PA of the palate. It exhibited extensive squamous metaplasia mimicking a squamous cell carcinoma (SCC) on multiple preoperative biopsies. The final diagnosis was only made after a complete oncological excision with margins and free flap reconstruction. Florid squamous metaplasia in a PA, although rare, should be recognized and distinguished from SCC. Failure to differentiate these entities can lead to patient overtreatment.

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
