Psoriasis – Inverse Psoriasis

Inverse Psoriasis is a type of Psoriasis which occurs in the skin folds and I encounter this skin disease often in both my The Woodlands dermatology and Conroe dermatology offices.  It is considered the “hidden Psoriasis” as the plaques are found in the axilla (underarms), groin, underneath the breasts, and below protuberant abdomens.  Friction, heat and moisture from sweat exacerbates Inverse Psoriasis.  The plaques of Inverse Psoriasis lack scale and appear very red or purple.  Candidiasis and tinea corporis are entities which Inverse Psoriasis may be commonly mistaken for.  The treatment of Inverse Psoriasis involves the use of topical steroids but ones with lower potency must be used as the affected areas are very sensitive.  Also, the occlusion from two skin folds can strengthen the potency of topical steroids.  I encourage my patients with Inverse Psoriasis to practice meticulous personal hygiene as this can improve their disease.
