Abstract

Gougerot–Carteaud syndrome or confluent and reticulated papillomatosis (CRP), was first described by Gougerot and Carteaud as dermatosis. 1,2 It is generally considered a rare condition. The eruption consists confluent, flat, brown papules localized primarily to the intermammary and interscapular regions with subsequent spread to the breast and abdomen; at the periphery, the papules spread out forming a pigmented reticulated pattern. At present, the aetiology of CRP remains unknown. The two prominent theories are an abnormal host response to fungi 3 and a keratinization defect. 4,5 Other hypothesis include photosensitivity, 6 genetic factor, 7 amylodosis cutis 8 and endocrinopathy. 9
