Pemphigus Erythematosus of the Scalp Developed Around the Postoperative Scar

We present a clinical case reflecting the difficulties of differential diagnosis of pemphigus erythematosus (PE) in a 40-yearold male presented with erythematous topic lesions, pustules, and crusts on the skin of the scalp and face, which had existed for the previous 20 years of his life. In our case, clinical manifestations of dermatosis were atypical due to the presence of pustules and crusts impregnated with seropurulent exudates, resistant to antibiotic therapy. The patient had areas of atrophy on the scalp that could be a sign of discoid lupus erythematosus. The negative results of tests for LE cells and double-strand DNA antibodies, as well as ineffective treatment with plaquenil, antibiotics and itraconazole, helped to verify the diagnosis of PE.
