Tumor mucinoso limítrofe paratesticular y carcinoma mucinoso: de retroperitoneo: a propósito de un caso

Los tumores testiculares y paratesticulares del tipo epiteliales son raros. Existe poca preferencia en la literatura de la variedad mucinosa. Se plantea controversia en la histogenesis debido a su asociacion con teratomas, y establecer origen germinal. Se presenta el caso de paciente masculino de 38 anos con clinica de dolor lumbar, masa abdominal palpable, aumento de volumen testicular izquierdo de 2 anos de evolucion. Se le practico orquidectomia izquierda con hallazgo de tumor quistico de 7 cm x 6 cm x 3,5 cm, de contenido mucoide; se reporto como tumor mucinoso de bajo grado de malignidad para testicular (limitrofe). En vista de sintomas abdominales compresivos, se realiza laparotomia exploradora, encontrandose tumor lobulado de 21 cm x 19 cm x 12 cm en el retroperitoneo, que correspondio a carcinoma mucinoso variedad intestinal desarrollado en teratoma quistico maduro. Se concluyo que ambos tumores no guardaban relacion entre si, se consideraron sincronicos.(AU) Testicular and par testicular tumors of type epithelial are rare. There is little reference in literature of mucinous variety; the vast majorities are serous. In this article we discussed the case of 38 year old male who presented with a two year history of left low quadrant pain, abdominal mass and enlarged left testicle. Left orchiectomy was performed finding a mucoid cystic tumor, measuring 7 cm x 6 cm x 3.5 cm which was reported as a low grade malignancy par testicular mucinous (tumor Borderline). Consequently, since compressive symptoms persisted,the patient underwent exploratory laparotomy. A lobular tumor measuring 21 cm x 19 cm x 12 cm was found in the retroperitoneum. It corresponded to mucinous carcinoma of the intestinal variety within a mature cystic teratoma. Based on these findings and after reviewing the literature it was concluded that both tumors were independent from each other, considering them synchronous tumors.(AU)
