There are several malignant or benign skin diseases which can be explained by the phenomenon of mosaicism or segmental manifestation, e. g. segmental neurofibromatosis 1 or cutaneous leiomyomatosis. Loss of heterozygosity is a crucial element for segmental manifestations. Two types of segmental manifestations can be defined in autosomal dominant skin diseases such as cutaneous leiomyomatosis. Type 1 is caused by a novel postzygotic segmental mutation; type 2 reflects an additional postzygotic loss of heterozygosity of the gene locus responsible for cutaneous leiomyomatosis in a initially heterozygous embryo. Loss of heterozygosity is a genetic process when a heterozygous cell becomes homozygous or hemizygous by loosing the corresponding wild-type allele. This phenomenon can be regarded as a precondition for tumor growth. In type-2 cases, the segmental manifestation is more distinctive with additional disseminated disease because of a germline mutation with heterozygosity of all somatic cells outside the strongly affected area.
