[Long-term paratesticular leiomyosarcoma. Conceptual and literature review]. / Leiomiosarcoma paratesticular de larga evolución. Revisión conceptual y de la literatura.

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 METHODS: 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.

[Epididymis trombosed hemangioma in old patient. Presentation of 1 case with conceptual review and of the literature]. / Hemangioma epididimario trombosado en paciente mayor. Presentación de 1 caso con revisión conceptual y de la literatura.

INTRODUCTION: Though theoretically in the paratesticular region one can develop any type of benign tumour of soft tissues, they are the lipomas, leiomyomas and adenomatoid tumours the most usual whereas the hemangiomas are less common. We contribute a new case of epididymis intrascrotal hemangioma (HI), valuing the bibliography that allows us to know the incidence and clinic-pathologic characteristics of these tumours. MATERIAL AND METHOD: A 74-year-old patient includes for study with right scrotal tumour, who is practised orchiectomy. Hystopathologic study is realized. Of equal form there is realized a bibliographical examination of this type of tumours across Medline and of not index-linked search with conceptual review and of the literature. RESULTS: The injury corresponds with a HI cavernous trombosed of epididymis with testicular parenchyma respected. Your hystopathologic diagnosis does not present problems, whereas the clinical one and ultrasonographic study, reaches the whole spectrum of tumours, benign and malignant of soft tissues. The number of intrascrotal hemangiomas of epididymis described in the literature is very limited. CONCLUSIONS: The scrotal tumours are necessary a preoperatory clinical and sonographic study completely, in spite of the fact that they are diagnosed the majority after your surgical removal. The complex system of the tissues on the zone paratesticular implies that the differential enclosed diagnosis does not allow to differentiate, malignant tumours of benign. The low incident of many of these masses has determined the mistake of standardized protocols for your diagnosis but also for their unified treatment.
