Localized pemphigus vulgaris on scalp: an atypical presentation.

This document discusses two cases of middle-aged patients with localized pemphigus vulgaris presenting as pruritic, crusted scalp erosions. Diagnosis was confirmed through skin biopsy showing epidermal acantholysis and IgG and C3 intercellular deposits. Treatment with low doses of oral prednisone and intralesional triamcinolone acetonide led to resolution of the lesions without relapse, highlighting an effective management approach for this atypical presentation.
