A rare case of lymphangioma of the scrotum in a 3 year old boy: a case report

Cystic hygromas, also known as lymphangiomas, are unusual congenital malformations of the lymphatic system. They are normally seen in the head and neck region and very rarely occur in the scrotum. This anomaly manifests as a painless scrotal swelling and is easily misdiagnosed. We report a rare case of a 3-year-old boy who presented with a gradually enlarging, painless scrotal mass which was identified sonographically and histologically as a scrotal lymphangioma and treated by surgical excision. A brief review of the literature is included.
