[Acute idiopathic scrotal edema].

A history of acute idiopathic scrotal oedema is described, for the first time in Norway. A four year-old boy with acute scrotal swelling and erythema was operated on. The operative findings were oedema in subcutis and dartos muscle. Acute idiopathic scrotal oedema is observed most often in prepubertal boys. It is recognized by acute uni/bilateral scrotal swelling, erythema and mild scrotal discomfort. The aetiology is unclear but the disorder is probably allergic in origin. It is best treated with rest in bed and observation.
