IgA vasculitis causes various symptoms such as purpura, arthralgia, and abdominal pain, but it also can cause scrotal symptoms in rare cases. Quincke’s edema is a well-known scrotal symptom associated with this disease, but scrotal symptoms may need to be treated as acute scrotal symptoms. This study reports a case of IgA vasculitis complicated by epididymitis. A 2-year-old boy was admitted with purpura and leg pain and diagnosed as having IgA vessels. However, swelling, redness, and pain in the scrotum were observed from the 4th day of admission. Ultrasound examination was negative for testicular torsion, but showed swelling and increased blood flow in the epididymis. Therefore, based on history of the patient, epididymitis associated with IgA vasculitis was diagnosed. Subsequently, the scrotal symptoms were resolved with improvement of IgA vasculitis. Acute scrotal disease associated with IgA vasculitis basically requires no treatment. In some cases, an experimental incision is performed to rule out testicular torsion, but in fact, the possibility of torsion is extremely low. In addition, scrotal symptoms may also precede purpura and other symptoms. Therefore, IgA vasculitis should also be considered as a differential disease for acute scrotal symptoms.
