An Unusual Case of Drug-Induced Linear IgA Bullous Disease
Bibliographic record
Abstract
We describe a case of vancomycin-induced linear IgA bullous dermatosis (LABD) with unusual features in a 75-year old woman who received intravenous vancomycin for methicillin-resistant Staphylococcus Aureus infection. Our patient demonstrated an unusual lesional distribution with initial facial involvement and a longer latent period than usual, which to our knowledge has not yet been reported in the literature. A skin punch biopsy including direct immunofluorescence study (IMF) confirmed the diagnosis of LABD. The patient’s cutaneous eruptions resolved over the next 14 days with stoppage of medication and supportive care without the need for systemic steroids. Physicians should be aware of this rare type of autoantibody mediated drug reaction in patients put on vancomycin. Early diagnosis using a skin punch biopsy with direct IMF study would avoid unnecessary laboratory investigations and initiate prompt management.

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.
