[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.

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

Introducción: Conocer la incidencia y características clínico patológicas del leiomiosarcoma (LMS) paratesticular con la aportación de un caso de larga evolución, estudiando los criterios histopatológicos que deben valorarse en este tipo deneoplasias. Material y métodos: Se incluye para estudio un paciente de 73 años con tumoración escrotal izquierda presente desde hace 30 meses. Se realiza estudio histopatológico e inmunohistoquímico. De igual forma se realiza un examen bibliográfico de este tipo de tumores y sus diferentes subtipos a través de Medline y de búsqueda no indexada. Resultados: Nuestro caso es el segundo de mayor evolución de la literatura internacional, el primero en mayores de 60 años y uno de los de menor índice mitótico (1 x 50 cga). Sin embargo, su atipia, necrosis tumoral próxima al 50% de la lesión y su pleomorfismo, así como su inmunofenotipo se corresponde con un LMS bien diferenciado grado 1 (French Federation Cancer).Hemos encontrado tan solo 107 casos publicados de este tipo de sarcomas, de ellos 5 en nuestro país, lo que da un perfil de la baja incidencia de estas neoplasias, que dentro de los sarcomas no alcanzan el 1%. Incluimos el perfil clínico patológico de los mismos. Conclusiones: La larga evolución de una tumoración paratesticular y la ausencia de metástasis no excluye su malignidad. La baja incidencia de los LMSs en esta localización implica que no exista un protocolo de actuación consensuado para los mismos. Consideramos de gran importancia su creación por parte de urólogos, oncólogos, radiólogos y patólogos al igual que se hizo con los localizados en retroperitoneo y tejidos blandos profundos (AU)

[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.

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

Introducción: Aunque teóricamente en la región para testicular puede desarrollarse cualquier tipo de tumor benigno de tejidos blandos, son los lipomas, leiomiomas y tumores adenomatoides los más frecuentes, mientras que los hemangiomas son menos comunes. Aportamos un nuevo caso de hemangioma intraescrotal (H I), localizado en epidídimo, valorando la bibliografía que nos permita conocer la incidencia y características clínico patológicas de estos tumores. Material y métodos: Se incluye para estudio un paciente de 74 años con tumoración escrotal derecha, a quien se practica orquiectomía. Se realiza estudio histopatológico. De igual forma se realiza un examen bibliográfico de este tipo de tumores a través de Medline y de búsqueda no indexada con revisión conceptual y de la literatura. Resultados: Se corresponde la lesión con un HI cavernoso trombosado de epidídimo con parénquima testicular respetado. Su diagnóstico histopatológico no presenta problemas, mientras que el clínico y ultrasonográfico, alcanza todo el espectro de tumores de partes blandas, benignos y malignos. El número de hemangiomas intraescrotales epididimarios descritos en la literatura es muy reducido. Conclusiones: Los tumores escrotales, precisan de un estudio preoperatorio clínico y ecográfico completo, a pesar de que la mayoria son diagnosticados tras su extirpación quirúrgica. El complejo sistema tisular de la zona paratesticular implica que el diagnóstico diferencial incluso no permita diferenciar tumores malignos de benignos. La baja incidencia de muchas de estas neoplasias ha condicionado la falta de protocolos estandarizados para su diagnóstico pero también para su tratamiento unificado (AU)
