Idiopathic scrotal fat necrosis: an unusual cause of scrotal pain.

The clinical differential diagnosis of scrotal pain with a mass in a prepubertal boy is difficult. Often conditions such as testicular torsion and epididymo-orchitis are diagnosed. We present a rare cause of scrotal pain, idiopathic scrotal fat necrosis. This condition has a typical clinical presentation and ultrasound findings that have been described in a limited number of case reports. However, if it is diagnosed correctly and confirmed with ultrasound, we hope that people will be treated without surgical intervention. We present a case of scrotal wall necrosis and a literature review. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2018. All rights reserved.
