© 2013 The Authors. doi: 10.2340/00015555-1437 Journal Compilation © 2013 Acta Dermato-Venereologica. ISSN 0001-5555 Chromosome 15q tetrasomy is in the heterogeneous group of extra-structurally abnormal chromosomes (1). The syndrome displays distinctive clinical findings represented by developmental delay, intellectual disability, epilepsy and autistic behaviour. Skin pigmentation has been observed in several cases (1). However, no previous reports have described the skin lesions in detail. We report here the first case of a patient with 15q partial tetrasomy syndrome who presented with skin pigmentation that was clinically and histologically consistent with confluent and reticulated papillomatosis (CRP).
