ABSTRACT

Confluent and reticulated papillomatosis is a disease characterized by patchy, verrucous and pigmented papular lesions that initially appear in the intermammary area and in the midback and, subsequently spread over the whole body. It was first reported by Gourget and Carteaud in 1927. The precise cause of confluent and reticulated papillomatosis is not known yet, but genetic keratinization disorder, reaction to pityrosporum ovale and to ultraviolet light are associated with this disease. Most cases are sporadic, but also familial cases have been reported. Confluent and reticulated papillomatosis is generally seen in young women and in those with dark skins. We report a forty-year-old male patient with the diagnosis of confluent and reticulated papillomatosis in whom the lesions initially appeared on the chest, and then involving the neck symmetrically, extended to the back of the ears.
