[Acute epididymitis in boys].

Acute scrotum in children frequently causes diagnostic difficulties. Instantaneous treatment is essential especially in cases of torsion of the testis. Acute epididymitis (AE) is relatively frequent also in prepubertal boys but is probably underdiagnosed. Two cases and a review of AE and the differential diagnoses towards other acute scrotal diseases are presented. It is stressed that immediate diagnosis and treatment is important, and that referral to hospital is mandatory.
