[2025-10-01T16:13:10.587082] [PI reasoning] **Identifying the disorder**

I’m trying to determine which disorder features a circulating antibody against the intercellular cementing substance of stratified squamous epithelium. The options are Lichen planus, Verruca vulgaris, Bullous pemphigoid, and Pemphigus vulgaris. 

In Pemphigus vulgaris, autoantibodies target desmoglein, causing cell separation, unlike Bullous pemphigoid, which targets hemidesmosomes. Lichen planus is T cell mediated, and Verruca vulgaris is from HPV infection. So, my answer is Pemphigus vulgaris, and I need to provide reasoning backed by standard literature.
