Fibrous pseudo tumor of the tunica vaginalis is a rare lesion affecting men representing a challenge in its diagnosis and treatment. We reported the case of a 17 year old male patient who presented for a right scrotal mass. Surgical resection of the mass was performed and the histological diagnosis was a fibrous pseudo tumor of the tunica vaginalis. It is usually affecting men in the third decade and the fear is to miss its main differential diagnosis which is testicular cancer. Studies should give more concern to this entity, so that we can avoid unnecessary orchiectomy.
