Management of spermatic cord tumors: a rare urologic malignancy.

Primary spermatic cord tumors are rare yet clinically significant urologic lesions that affect patients of all ages. They are the most common tumors of the paratesticular region and generally present as asymptomatic, slow growing, firm, palpable paratesticular masses. Although most of them are benign comprised primarily of lipomas, approximately 25% are potentially life-threatening malignant tumors. The most common reported malignant histological types include liposarcomas, leiomyosarcomas, rhabdomyosarcomas, malignant fibrous histiocytoma, and fibrosarcomas. Management of these malignant tumors has been difficult because of their rarity, therefore there is little consensus regarding optimal surgical and adjunctive treatment strategies. It is recommended that radiological techniques such as scrotal ultrasound (US), computed tomography, and magnetic resonance be used to evaluate these masses before surgery. The curative treatment of choice is radical orchiectomy with high cord ligation and wide excision of surrounding soft tissue structures within the inguinal canal. Patients with inadequately resected disease should undergo a reoperative procedure for wide inguinal re-resection. Retroperitoneal lymphadenectomy is recommended when there is preoperative evidence of retroperitoneal lymph node metastasis and as an adjuvant treatment for rhabdomyosarcomas since they have a higher propensity for lymphatic spread. Adjuvant treatments, such as radiotherapy and chemotherapy, have shown little efficacy, except in the management of patients with local recurrence or high-grade rhabdomyosarcomas. Long-term follow up is recommended given their high recurrence rates.
