Bullous presentation of Henoch-Schönlein purpura in an adult.

Henoch-Schönlein purpura is a small vessel vasculitis occurring mainly in childhood and rarely in adulthood. Typical cutaneous eruption may begin as macular or urticarial erythematous lesions progressing to a palpable purpura. In adults, the disease has a propensity to be more severe and chronic and affects mainly the ankles and feet. Bullae, vesicles and ulcers are occasionally seen in this group. The prognosis depends on renal involvement, commonly seen in adults. We report a new case of Henoch-Schönlein purpura in a 36-year-old man presenting with a bullous eruption followed by the appearance of abdominal pain and hematuria.
