Psoriasis
Psoriasis : Common chronic, squamous dermatosis, marked by exacerbations and remissions and having a polygenic inheritance pattern. The most distinctive histological findings in well-developed psoriasis are Munro microabscesses and spongiform pustules. It is characterized clinically by the presence of rounded, circumscribed, erythematous, dry, scaling patches of various sizes, covered by grayish white or silvery white, umbilicated, and lamellar scales, which have a predilection for the extensor surfaces, nails, scalp, genitalia, and lumbosacral region. Central clearing and coalescence of the lesions produce a wide variety of clinical configurations, including annular or circinate, discoid or nummular, figurate, and gyrate arrangements. Also called psoriasis vulgaris
