Confluent and reticulated papillomatosis (CRP) is a rare disease presenting with keratotic pigmented papules located mostly on the chest, neck and trunk with unknown etiology. Genetic, keratinization abnormalities, abnormal host reaction to fungal or bacterial infections and endocrine diseases are suspected in the etiopathogenesis. The role of heredity in the pathogenesis of CRP arised with the familial case reports. There are sporadic case reports whereas familial reports are rare in the literature. Here, we present 22 and 20 year-old two brothers with familial confluent and reticulated papillomatosis. Our cases who live apart in different countries with different environments and climates, supply strong evidence for the genetic basis of the disease. This two brothers with CRP are presented due to rare familial occurence. (Turk J Dermatol 2012; 6: 108-10)
