Some patients display mild disease with isolated scaling erythematous plaques on the elbows or knees, whereas for others most of their cutaneous surface can be affected. At the cellular level, psoriasis is characterised by markedly increased epidermal proliferation and incomplete differentiation, elongation, dilation, and leakiness of the superficial plexus of dermal capillaries, and by a mixed inflammatory and immune cell infiltrate of the epidermis and papillary dermis.1,2 Dermal infiltrates comprised of T cells and macrophages typically appear in early lesions before epidermal changes.4 The therapeutic effect of immunosuppressive agents suggests psoriasis has a primary immune pathogenic basis.5 inflammatory and immune cell infiltrate of the epidermis and papillary dermis.1,2 Dermal infiltrates comprised of Ten-USpsoriasisPSORS2genome-wide scan17q terminustubulin- specific chaperone d genejournal article
