RUIZ LISO, J.M. et al. Long-term paratesticular leiomisarcoma: Conceptual and literature review. Actas Urol Esp [online]. 2008, vol.32, n.7, pp.727-736. ISSN 0210-4806.

Introduction: To know the incidence and clinical and pathologic characteristics of the paratesticular leiomyosarcoma (LMS) with the contribution of a case of long evolution, studying the histopathologic criteria that must be valued for this type of tumours. Material and metods: A 73-year-old patient includes for study with scrotal tumour present left side for 30 months. Histopathologic and imunohistochemical study is realized. Of equal form there is realized a bibliographical search of this type of tumours and their different subtypes across Medline and of not index-linked search. Results: Our case is the second of greater evolution of international literature, first in greater of 60 years and one of those of smaller mitotic index (1 x 50 cga). Nevertheless, his atipia, tumorlike necrosis next to 50% of the injury and its pleomorphic properties, as well as his inmunophenotypic characterization corresponds with a well differentiated LMS, degree 1 (French Federation Cancer). We have found only 107 published cases of this type of sarcomas, of them 5 in our country, which gives to a profile of the low incidence of these tumours, that within sarcomas 1% do not reach. We included the clinical and pathologic profile of such. Conclusions: The long evolution of a paratesticular tumour and the absence of metastasis does not exclude its malignancy. The low incident of the LMSs in this location, implies that a protocol of actuation validate for such does not exist. We considered of great importance, its creation on the part of urologist, oncologists, radiologists and pathologists like he took control of located in retroperitoneal cavity and deep soft tissues.
