Liposarcoma del cordón espermático

Abstract

Introduction: liposarcoma of the spermatic cord (LSC) is a rare condition and accounts for about 3 to 7% of all paratesticular sarcomas. A case is presented in an 80-year-old patient who consulted for a left inguinoscrotal painless swelling, that had been present for several years. Physical examination revealed a soft left hemiscrotal tumor that appeared not to be adherent to the testicle. Ultrasonography showed a solid, heterogeneous hyperschoic paratesticular mass with central calcifications and peripheral hypervascularity. During surgery, a diffuse lipomatous tumor was found in the spermatic cord on the superior pole of the left testicle, separated from it. Anatomopathological examination revealed a well-differentiated liposarcoma of the spermatic cord. Discussion: this neoplasm features a slow-growing palpable paratesticular mass. This site of occurrence is rare and represents 7 to 10% of all scrotal tumors. Imaging differentiation between LSC and benign lesions is sometimes challenging. Surgical treatment should include radical orchiectomy wide local excision, and spermatic cord and inguinal ring surrounding soft tissue resection. Conclusion: spermatic cord liposarcoma is a rare and unusual mesenchymal tumor and should be considered among the differential diagnoses of scrotal tumors.
