Trigeminal trophic syndrome associated with post-herpetic neuralgia – report of a rare case with review of literature
Bibliographic record
Abstract
Trigeminal trophic syndrome is a rare clinical entity characterized by a triad of ala nasi ulceration, trigeminal anaesthesia and paraesthesia. Objective. To report a patient with painless facial and scalp ulceration which was diagnosed as trigeminal trophic syndrome following herpes zoster. Case report. A 72-year-old man, who had suffered from herpes zoster in the trigeminal nerve distribution 6 months prior, presented with a 3-month history of unilateral facial and scalp ulceration in the same distribution. Diagnosis of trigeminal trophic syndrome was reached after excluding infectious, malignant and granulomatous conditions. Conclusions. Post-herpetic trigeminal trophic syndrome has been scarcely reported. Reports on this rare entity can be found both in dermatological and otolaryngology literature due to overlapping nature of the condition which makes it important for both these specialities. We are reporting this case due to the paucity in world literature and to apprise the clinicians about this unusual condition to reduce the risk of misdiagnosis.

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.
