[Inflammatory malignant fibrous histiocytoma of the spermatic cord infiltrating an inguinal leiomyoma. Case report with conceptual and bibliographic reviews].

Objectives: To study paratesticular malignant fibrous histiocytomas (FHM) from the clinical, histological, immunohistochemical and histogenetic, point of view.

Methods: Through Medline and not index-linked search of international scientific literature we have found a total of 77 cases of paratesticular FHM that globally create diagnostic, terminological and therapeutic problems.

Results: We include the case number 78 of FHM of spermatic cord, that presents a few special characteristics (not described before) of cutaneous fistula and infiltration of an inguinal leiomyoma, with histological and immunohistochemical confirmation.
