Abstract
Inverted papillomas (IP) in children are extremely rare, benign epithelial growths known to recur. DEF-AFF2 squamous cell carcinoma (SCC), a newly identified, aggressive, and metastatic non-keratinizing SCC, can mimic IP. A 15-year-old male presented with recurrent episodes of left dacryocystitis and epiphora. His exam revealed left nasolacrimal duct obstruction, and an endonasal dacryocystorhinostomy was planned. Intraoperatively, there was a sudden prolapse of soft tissue after incising into the left lacrimal sac. Lesion biopsy initially revealed pathologic features consistent with inverted papilloma; however, RNA sequencing revealed a DEF-AFF2 fusion reclassifying it to SCC. Otolaryngology performed staged debulking followed by proton radiotherapy. There was no evidence of recurrence for 18 months. DEF-AFF2 SCC is a distinct, locally aggressive tumor with rare involvement of the lacrimal apparatus. Combined surgical and radiation therapy lead to adequate response. Accurate diagnosis requires a multidisciplinary approach due to its challenging and rare presentation, particularly in an atypical age group.

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
