| psoriasis |
a common chronic, squamous dermatosis with polygenic inheritance and a fluctuating course. Principal histological findings are Munro microabscesses and spongiform pustules; also seen are rounded, circumscribed, erythematous, dry, scaling patches of various sizes, covered by grayish white or silvery white, umbilicated, and lamellar scales, usually on extensor surfaces, nails, scalp, genitalia, and the lumbosacral region. Central clearing and coalescence of the lesions produce lesions of diverse shapes, including annular or circinate, discoid or nummular, figurate, and gyrate.
