Large cist of the tunica albuginea

Introduction. A cyst of the tunica albuginea of the testis is a rare benign formation, the prevalence in the male population varies from 0.3 to 0.76%. Cysts of the tunica albuginea are usually small in size from 2 to 5 mm. Clinical case. A case of a large cyst of the tunica albuginea (3.5x2.5x2.9 cm) of the left testicle in a 44-year-old man is presented. In the case presented, the cyst was probably of post-traumatic origin, since the patient had suffered a blunt trauma to the scrotum about 10 years ago. The patient complained of pain in the left half of the scrotum. An operation was performed microsurgical excision of the cyst of the albuginea of the left testicle. Postoperative period without complications. The pain syndrome was relieved 14 days after the operation. Histological examination a cystic formation with a connective tissue wall lined with cubic, in places ciliated epithelium. Ultrasound control after 3 months the size of the left testicle is 4.2 * 2.7 * 1.9 (volume 11.2 cm3), the parenchyma is homogeneous. Conclusion.The presented observation demonstrates that cysts of the albuginea of the testis can reach a significant size, spreading into the testicular parenchyma. Organ-sparing treatment in symptomatic patients with large cysts of the albuginea with intraparenchymal growth allows to eliminate pain symptoms and preserve the residual testicular parenchyma. The use of microsurgical techniques may be useful in minimizing circulatory disturbance and reducing the risk of atrophic changes in the testicular parenchyma.
