484 JEADV 2006, 20, 461–488 © 2006 European Academy of Dermatology and Venereology are not absolute diagnostic criteria. Microabscesses of Munro, typically found in psoriatic lesions, can be found in ILVEN as well. In a recent and interesting study, Vissers et al. compared by quantitative immunohistochemistry the subsets of T lymphocytes and markers for epidermal growth and keratinization in biopsies taken from skin lesions of patients with psoriasis and patients with ILVEN. Differences found in the number and expression of the markers studied may suggest a differential point in the future. On the basis of the pathogenesis, an infection may be a stimulus for the clonal inflammation in both entities. Their linear arrangement possibly reflects somatic mosaicism for a gene. Is it a gene for psoriasis? Why are patients with ILVEN susceptible to psoriasis or have a family history of it? Both, ILVEN and linear psoriasis, can occur in the presence of generalized psoriasis. When each disorder remains linear and isolated, it corresponds to Happle’s type I mosaicism. The presence of diffuse and more severe lesions corresponds to the recently described type 2 segmental mosaicism with loss of heterozygosity. It is possible that a germline mutation for the disease exists but, in addition, a postzygotic mutation is needed resulting in loss of heterozygosity. Studies of the molecular basis for both types of gene mosaicism will demonstrate the correlation of mosaic genotype and phenotype in the future. In a few cases, the association of ILVEN with arthritis and with autoimmune lymphocytic thyroiditis makes also an immune involvement seem probable. Many authors have suggested that linear psoriasis is an ILVEN or the result of an isomorphic effect on a preexisting epidermal naevus. Could it be the opposite? We propose that ILVEN might be a form of linear psoriasis. Clearly more data are needed to support this suggestion.
