Peri‐Implant <i>Epstein–Barr</i> Virus (+) Mucocutaneous Ulcer in an Immunocompetent Patient: Case Report and Review of the Literature
Bibliographic record
Abstract
Epstein-Barr virus (+) mucocutaneous ulcer (EBVMCU) is an uncommon benign lymphoproliferative lesion that develops in immunocompromised patients. We present a special case of EBVMCU located in the peri-implant mucosa and we review the oral cases published to date. An 88-year-old man with no medical history of interest was attended in the dental clinic due to an ulcerated tumor located in the peri-implant mucosa. The lesion showed an atypical lymphoid proliferation, positive for CD3, CD20, CD30, PAX-5, and MUM1. Positive EBV and favorable patient evolution confirmed the final diagnosis of EBVMCU. Oral EBVMCU reports related to immunosenescence mainly develop in the gingiva of advanced age patients. Our case highlights the importance to perform a complete clinicopathological study of all peri-implant lesions. Although most peri-implant pathologies are inflammatory-reactive disorders, sometimes they can also correspond to other entities.

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.
