Confluent and reticulated papillomatosis of Gougerot and Carteaud, besides being a mouthful to say, is a relatively uncommon skin disease that usually affects young people. It’s characterized by gray-bluish papules (or inflamed bumps on the skin) usually limited to the central trunk area, though it can occasionally spread to the shoulders, pubic area, and face. The disease — which can be caused by an endocrine disturbance, a bad reaction to fungi or bacteria, or be heriditary — is chronic, with periods of exacerbations and remissions. Lesions group up and form a net-like pattern. Many of those who experience the disease are asymptomatic, though itching may occur in some. Those who contract the disorder usually do so right after puberty.
