Bilateral Multifocal Warthin Tumors Mimicking Metastatic Papillary Thyroid Carcinoma: A Rare Case Posing a Diagnostic Challenge
Bibliographic record
Abstract
Abstract Warthin tumor is the second most common benign tumor of parotid gland. It rarely may be multifocal and occur at extraparotid sites, most common being the cervical lymph nodes. Fine-needle aspirate cytology is diagnostic in most cases of parotid Warthin tumors; however, in extraparotid sites, the diagnosis can be challenging. The difficulty can be further amplified if there is a synchronous lesion in a visceral organ on radiology, raising the suspicion of a metastatic carcinoma. We report an unusual diagnostically challenging case of synchronous, bilateral, multifocal intraparotid and extraparotid Warthin tumors mimicking a metastatic papillary thyroid carcinoma. We also highlight the usefulness of intraoperative consultation in guiding appropriate management in such cases.

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.
