Localized pemphigus vulgaris on scalp: an atypical presentation.

We present two middle-aged patients with pruritic, crusted scalp erosions. Skin biopsy showed epidermal acantholysis with IgG and C3 intercellular deposits on direct immunofluorescence, leading to the diagnosis of localized pemphigus vulgaris. Resolution of the lesions without relapse occurred after low doses of oral prednisone and intralesional triamcinolone acetonide.

High Frequency of Severe Telaprevir-associated Skin Eruptions in Clinical Practice.

Since the introduction of telaprevir, administered in combination with pegylated interferon and ribavirin for the treatment of patients with chronic hepatitis C, the incidence and severity of skin eruptions have increased significantly. The aim of this prospective study is to assess the frequency of drug-induced skin eruptions and their clinical and histological characteristics in patients who received the above treatment in daily clinical practice at our hospital. A total of 60 patients were included.
