Tumor adenomatoide urológico: presentación clínico-patológica de 14 casos

El Tumor Adenomatoide es la neoplasia paratesticular mas frecuente y localizada principalmente en el epididimo. Material y metodo: Se presenta una serie clinico-patologica de 14 tumores adenomatoides urologicos diagnosticados entre 1975-2011. Resultados: La edad media de presentacion fue de 46 anos (rango 32-67 anos). La mayoria de los casos se presento como un nodulo firme indoloro en el epididimo. No hubo casos de localizacion intratesticular. Se realizo tumorectomia en 13 casos y ademas orquiectomia en uno. Los tumores midieron una media de 1.9 cm (rango 0.3-5 cm) y macroscopicamente fueron solidos, blanquecinos y bien delimitados. A la histologia estaban formados por estructuras adenomatoides irregulares rodeadas por tejido fibroso. La inmunotincion para Queratina y Calretinina fueron positivas, lo que apoya el origen mesotelial del tumor. El curso clinico fue benigno en todos los casos, sin presentar recurrencias. Conclusion: Corresponde a una neoplasia benigna urogenital rara de origen mesotelial y que compromete con frecuencia el epididimo. Se presentaron en hombres de edad media y que en la mayoria fueron tratados con tumorectomia, mostrando un curso clinico benigno...(AU) Adenomatoid Tumor is the most frequent paratesticular neoplasia and it is located mainly in the epididymis. Material and methods: A series of 14 cases of Urological Adenomatoid Tumor diagnosed between 1975 - 2011 is presented. Results: Average age at presentation was 46 years (range 32-67 years). The majority of the cases were presented as a painless and firm nodule in the epididymis. No cases involving the testicular parenchyma were seen. The tumors measured an average of 1.9 cm (range 0.3 - 5 cm) and grossly all cases were solid, whitish and fair/y well demarcated. The histology revealed adenomatoid structures surrounded by fibrous tissue. The immunostains were positive for keratin and calretinin which support‘ the mesothelialial origin of the tumor. All cases showed a benign clinical course and no relapses were found. Conclusion: Correspond to a rare benign urogenital/neoplasia that frequently involves the epidermis. They were presented in middle age men and in the majority of the cases were treated by lumpectomy, showing a bening clinical course...(AU)
