Secondary Cicatricial Scalp Alopecia Caused by Brunsting-Perry Pemphigoid: A Case Report
Bibliographic record
Abstract
Brunsting-Perry pemphigoid is a rare, chronically persistent bullous dermatosis, localized to the head, scalp, and neck, causing residual scars and cicatricial alopecia. Herein, we present a case of Brunsting-Perry pemphigoid in a 68-year-old Caucasian woman presenting with over 10 years of history of slowly progressing patchy cicatricial alopecia. Dermoscopy showed scarring, a milky red background, and a typical picture of a "fried-egg sign" representing specific follicular damage. A skin biopsy revealed a subepidermal blister with dermal inflammation. Immunopathology shows strong linear continuous deposits of C3c and IgM along the basement membrane, and moderate to weak linear reactions to IgG and IgA. Intralesional betamethasone was successful in the treatment, and topical mometasone furoate lotion was used to maintain the result. Our case suggests that Brunsting-Perry pemphigoid may be underdiagnosed as the reason for scarring alopecia, considering the scarce information about the disease in the literature.

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.
