RESUMEN
Vesical nephrogenic adenoma is a rare, benign entity that appears most commonly in middle-aged males. Its etiology is unknown, but it has been linked to chronic irritating factors, such as infection, trauma, urological surgery, kidney stones, foreign bodies and chemical agents, such as Bacille Calmette-Guerin. We report 2 new cases with a history of transurethral resection of the bladder and the prostate and a history of prolonged voiding symptoms. In both cases, the findings of encysted tubular structures lined with flattened cuboidal cells without atypia were consistent with the diagnosis of vesical nephrogenic adenoma.
RESUMEN
OBJECTIVE: To report one case of bilateral synchronic germ cell testicular tumour of different histology. METHODS/RESULTS: 37 year-old patient with left testicular tumor under study was found to have a contralateral synchronic testicular tumor on ultrasound. Bilateral inguinal orchiectomy was performed and pathology reported the presence of bilateral testicular tumours of different histological type. CONCLUSIONS: Around 75% of the cases of bilateral testicular tumours are metachronic, with only 10% presenting different histology. Histological type often correlates with the ultrasound findings, and the treatment of choice in patients with this type of oncological pathology is bilateral inguinal orchiectomy.
