Genitourinary complications of epidermolysis bullosa.

Epidermolysis bullosa is a rare inherited bullous disorder of the skin that occasionally involves the urinary tract. We describe a child with a history of epidermolysis bullosa who presented with hematuria, urgency, and dysuria. On radiographic investigation, bladder wall lesions were found. On cystoscopy, these were bullous lesions on the urinary bladder that at biopsy were shown to have inflammatory changes without evidence of malignancy. This is consistent with rare involvement of the bladder in epidermolysis bullosa. Symptomatic treatment resolved this patient's urologic complaints.
