title: Meconium periorchitis--a rare cause of a paratesticular mass.
abstract: We report a 9-month-old boy who presented with a hard paratesticular mass. Clinical and ultrasound findings were highly suggestive of malignancy and orchidectomy was performed. Histology confirmed the unexpected diagnosis of meconium periorchitis, a rare, benign condition resulting from intrauterine bowel perforation.
