In cases involving inverse psoriasis, a variant of psoriasis that affects intertriginous areas (ie, axillae, inguinal folds, inframammary creases), plaques have minimal scale.

Fissuring within psoriatic plaques can occur when lesions are present over joint lines or on the palms and soles. Psoriatic plaques are normally pink-red and raised, often with a characteristic silvery-white or micaceous scale. They are raised and easily palpable due to the thickened epidermis, expanded dermal vascular compartment, and infiltrate of neutrophils and lymphocytes that is characteristic of the disease. Psoriatic plaques are symmetrically distributed over the body.
