Flexural psoriasis

Flexural psoriasis may occur:

• in conjunction with typical plaque lesions elsewhere, or
• in conjunction with nail and scalp lesions only, or
• alone

Lesions may occur in any or all of:

• groin
• natal cleft
• axillae
• umbilicus
• submammary glands (1)

Such lesions often present as well defined, erythematous, shiny rashes lacking scale on account of heavy maceration (1). The plaques are frequently itchy.
