Flexural Psoriasis in the Armpit

Flexural psoriasis in the armpit. Psoriasis in the armpits, groins and gluteal cleft presents with non-scaling, well-defined, reddened patch that is easily weeping. Unlike eczema, it has more distinct margins, is located at the bottom of the armpit and does not itch. In seborrhoeic eczema, a similar but often less marked patch may be found at the bottom of the armpit. To confirm the diagnosis, skin biopsy may be required.
