Balanitis circinata

Balanitis circinata (also known as circinate balanitis) is a skin condition comprising a serpiginous ring-shaped dermatitis of the glans penis. While circinate balanitis is one of the most common cutaneous manifestations of reactive arthritis, it can also occur independently. Topical corticosteroid therapy is the most commonly used treatment, and topical calcineurin inhibitors have also been used successfully.
