Epidermodysplasia verruciform-like Lesions in an HIV patient.

Epidermodysplasia verruciformis (EV) is a rare disorder involving widespread infection with specific human papillomavirus types and characteristic clinical lesions that may resemble verruca plana, tinea versicolor, psoriasis, or seborrheic keratoses. The most common HPV types found in EV are 5, 8, 17, and 20. Histopathologically, lesions demonstrate stereotypical enlarged keratinocytes in the upper epidermis with gray-blue cytoplasm, enlarged round nuclei with pale chromatin, and one or multiple nucleoli. Epidermodysplasia verruciformis may occur in either a classical form (often familial, early onset, and complicated by squamous cell carcinoma) or in association with various hereditary or acquired immunodeficiencies, particularly HIV. Fewer than 20 cases of HIV-associated epidermodysplasia verruciformis have been reported. We describe a 42-year-old HIV-positive man who presented with hypo- and hyperpigmented papules and plaques on the upper trunk, head, and neck, with histopathologic findings of epidermodysplasia verruciformis.
