A Case of Lichen Sclerosus et Atrophicus With Distinct Erythematous Borders
Bibliographic record
Abstract
BACKGROUND: Lichen sclerosus et atrophicus (LSA) is a chronic inflammatory and fibrosing condition that mostly affects the genital mucosa. Nongenital skin may be affected either in isolation or in association with genital involvement. A distinct, brightly red border may be seen but is poorly documented in major dermatology texts. In the case presented, such a border was noted in all of the patient's very extensive lesions. OBJECTIVE: To draw attention to this clinical manifestation and to stimulate future observations as to its clinical and prognostic significance. METHODS AND RESULTS: A 67-year-old woman presented with disseminated LSA with genital involvement. All the lesions had a distinct red border. A review of major textbooks available to the authors revealed that the presence of a marginal erythema is regularly not mentioned. CONCLUSION: An erythematous border to LSA may be a notable feature. Its frequency and clinical significance remain to be determined.

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.
