Henoch-Schonlein purpura involving the glans penis.

Henoch-Schonlein purpura is a systemic vasculitis syndrome characterized by palpable purpura, glomerulonephritis, arthralgias, and gastrointestinal signs and symptoms. This syndrome typically presents in children between the ages of 4 and 7 years. Renal involvement can be progressive, irreversible, and fatal. Although skin lesions are frequently found on the scrotum and have been described on the penile shaft, no cases of glandular involvement have been previously reported. We describe the presentation of a 4-year-old boy with extensive involvement of painless purpuric lesions on his penile shaft, scrotum, and glans penis.
