[Mesenchymatous tumor of the spermatic cord with late recurrence in the retroperitoneal space. Apropos of a case]. / Tumeur mésenchymateuse du cordon spermatique avec récidive tardive dans l'espace rétro-péritonéal. A propos d'une observation.

The reported case is characterized by the original tumor site as well as by the recurrence site; by the slowly evolutive nature of the lesion over nine years from the time of surgical tumor excision to relapse; and by histological variations raising a nosological problem. Our clinical, anatomopathological and therapeutical observations are based on the characteristics of the case as well as published data. We only traced 5 cases in the literature of spermatic cord tumors with retroperitoneal localization. The progressive histologic polymorphism of these tumors compels us to raise the question of the very nature of this neoplasm: liposarcoma or malignant mesenchymoma. The potential clinical and histologic outcome of mesenchymal tumors of the spermatic cord cause us to propose direct orchidectomy and surveillance of the retroperitoneal space throughout the evolution of the process, even far off into the future.
