Epidermoid Cyst Presenting in the Floor of the Mouth
Bibliographic record
Abstract
Dermoid cysts are developmental malformations due to a defect in the fusion of embryonic lateral mesenchymatic layers during the fifth week of embryological development. Thirty-four percent of dermoid cysts occur in the head and neck area, of which 6.5% are in the floor of mouth. We present a rare case of a 17-year-old female with epidermoid cyst presenting in the floor of the mouth. A working diagnosis of a “plunging ranula” was concluded following salivary gland multidisciplinary team (MDT) meeting and the patient subsequently underwent an excision of lesion with right sublingual gland via an intraoral approach under GA. However, the pathology revealed the lesion consistent with an epidermoid cyst. We discuss the numerous pathological conditions that can affect the floor of the mouth, and differential diagnoses of lesions of a development, inflammatory, obstructive or neoplastic origin. Imaging aids such as ultrasound, MRI, and CT of head with contrast area are of valuable importance for estimating tumor margins and lesion composition, and assessing infiltration in surrounding tissues along with MDT which give platform with other departments to help form a working diagnosis and guide surgical approach.

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.
