Hemangioma with Phleboliths in the Floor of the Mouth Presenting as a Submental Swelling: A Case Report
Bibliographic record
Abstract
A painless, soft swelling in the submental area usually indicates the presence of a thyroglossal duct cyst, congenital sublingual dermoid cyst, amyloidosis, ranula, or cystic hygroma. We described a case of relatively rare hemangioma with multiple phleboliths in the floor of the mouth presenting as a submental swelling. We report a case of 17-year-old Japanese female who presented with the mass in the submental region that had been slowly growing for several years. The doppler ultrasonography revealed blood flow in the region. Computed tomography (CT) showed several round calcified foci, and magnetic resonance imaging (MRI) revealed a 20 x 45 mm lesion in the floor of the mouth. The lesion had high intensity on T2-weighted images and isointensity with muscle on T1-weighted images. Therefore, preoperative diagnosis has truly been established, although hemangioma with multiple phleboliths in the floor of the mouth presenting as a submental swelling is relatively rare. doi:10.4021/jmc108w

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.
