While confluent and reticulated papillomatosis (CRP) was first described by Gougerot and Carteaud1 in 1927, its pathophysiology is still not understood. We report familial CRP in 2 brothers with characteristic clinical features. Ultrastructural and immunohistochemical findings in both cases suggest that familial CRP is related to abnormal keratinocyte differentiation.
