This image depicts a close view of a patient’s penis, which revealed the presence of cutaneous lesions about the glans penis, and distal penile shaft, which were found to have been due to a condition known as Reiter’s syndrome. This condition is referred to as circinate balanitis, and manifests as serpiginous annular dermatitic lesions of the glans penis. Reiter’s syndrome, sometimes referred to as seronegative spondyloarthropathy, or reactive arthritis, consists of predominately three symptoms: arthritis, conjunctivitis, and urinary tract infections, or urethritis. More recently, doctors have recognized a fourth major feature, ulcerations of the skin and mouth. See PHIL 5794, for a view of a patient’s feet displaying this form of skin lesion.
