Benign cystic lesion of the tunica albuginea: a case report.

We describe a patient whose testicular parenchyma was displaced by a cyst. Histologic findings suggested that the cyst was a dilated efferent ductule passing through the tunica albuginea. Such a cyst is an important and benign consideration in the differential diagnosis of testicular masses. Although orchiectomy was performed in this case, early consideration and confirmation of benign lesions may permit testicular preservation.
