[2025-09-30T20:34:48.169737] [PI reasoning] **Identifying blister types**

I need to answer the question about where intra-epithelial bullae are found. So, I'm considering options like Pemphigus, Bullous Pemphigoid, Bullous Lichen Planus, and Pemphigoid. I recall that intra-epidermal or intraepithelial blisters mainly occur in pemphigus vulgaris. The other conditions, including Bullous Pemphigoid and Bullous Lichen Planus, tend to form subepidermal bullae. Therefore, the answer seems to be A. I should find and include some citations as well.
