[Acute Scrotal Swelling Caused by IgA Vasculitis : A Case Report]

The patient was a 4-year-old boy. He consulted our hospital's Dermatology Department for diffuse pruritic erythema on his extremities. Toxicoderma was suspected and a topical steroid was prescribed. Nine days later, when the boy was taking a bath, his mother noticed swelling of his scrotum and consulted a local pediatrician. The pediatrician suspected acute scrotal swelling and referred him to our department the same day. Purpura was found on the bilateral scrotum and prepuce ; edema was also present. Physical examination revealed mild tenderness of the bilateral scrotum. Purpura was present from the right inguinal region to the ipsilateral femoral region. Color Doppler ultrasonography confirmed the presence of blood flow in both testes, and edematous changes were found on the scrotal skin. On the basis of the clinical course of the skin lesions as well as physical and ultrasonographic findings, the condition was diagnosed as acute scrotal swelling caused by IgA vasculitis. After four days of rest, significant improvement in scrotal and preputial edema as well as in the right inguinal region was observed.
