Meconium Periorchitis

Abstract

Meconium periorchitis (MPO) is an unusual entity that presents as a scrotal mass in the early neonatal period and is seen in 1 in 30,000 live births. MPO is associated with meconium peritonitis, that leads to leakage of sterile meconium through patent processus vaginalis into the developing scrotum. Clinically, this entity presents as a para-testicular mass which shows scattered calcifications on imaging, thus warranting diagnostic work up and histopathological confirmation. Our case is an 8 month-old male baby with a firm to hard scrotal cyst. Intraoperatively, a diagnosis of teratoma was considered due to the complex solid cystic nature of the lesion and it was excised. Histology confirmed the diagnosis of MPO. Although some cases of MPO show spontaneous regression, about 65% warrant a surgical intervention. However, lack of awareness of this entity can lead to unnecessary orchiectomy.
