An Underappreciated Etiology of Groin Mass: Great Saphenous Vein Aneurysm.

Inguinal masses have a large variety of causes, ranging from inguinal hernias to soft tissue sarcomas. One of the less prevalent causes is vascular origin. Venous aneurysms, unlike their arterial counterparts, are seen seldomly and experience in management of these cases is scarce. A 32-year-old male patient was referred to our clinic due to an enlarging left inguinal mass with a preliminary diagnosis of inguinal hernia. Doppler ultrasonography revealed an eight cm in diameter aneurysmatic Great Saphenous Vein segment located just below the inguinal ligament. Dilated segment was excised without complete resection. Removal of the dilated segment and performing complete venous resection depending on venous valvular failure constitutes surgical repair of Great Saphenous Vein aneurysms. Surgical approach should be primarily selected if Great Saphenous Vein aneurysm is detected due to its debilitating nature and possible rupture.
