Objective: To describe the clinical presentation, preoperative diagnostic possibilities, and treatment of cystic nephroma.
Methods: We describe a case of cystic nephroma in an adult male and show that, both in our patient and in the literature, a definitive diagnosis can only be obtained postoperatively, even when there is a reasonable clinical suspicion.
Conclusions: Cystic nephroma is rare, and some authors consider it a questionable entity.
Objective: To describe a case of para-urethral leiomyoma and to review the literature.
Methods: The usual preoperative diagnostic procedures and clinical manifestations are discussed.
Results: The mass was resected and, 6 years later, the patient remains asymptomatic and with no recurrence.
Objectives: Neuroendocrine tumors (NET) are cancers found in the bronchopulmonary tract, where they were first described in 1926. The tumors are associated with poor prognosis due to their high metastatic potency even after radical treatments associated with other neo- or adjuvant therapies. NET of the urinary bladder is a rare tumor and accounts for 0.

Methods: Disorders of sex development with mismatch of genetic, gonadal and phenotypic sex are quite rare, and some are due to genetic or chromosomal abnormalities. The karyotype was investigated by a cytogenetic study of peripheral blood (phytohemagglutinin-timulated lymphocyte culture over 72 hours).
Objective: To describe two cases of urothelial tumors in inguinoscrotal bladder hernias and comment on the low incidence of this condition.
Methods: Two patients were diagnosed and treated by partial cystectomy and hernia repair.
Results: The clinical outcome of both patients was good at two and three years, respectively, and neither patient experienced hernia or tumor recurrence.
Objective: To study and review spermatic cord sarcomas, including symptoms, diagnosis, and treatment.
Methods/results: We review the Spanish and international literature and report 4 new cases: 2 patients with well-differentiated spermatic cord liposarcomas (1 treated by simple tumorectomy), 1 patient with liposarcomatous degeneration of a previously excised atypical lipoma, and 1 patient operated for a malignant retroperitoneal fibrous histiocytoma with subsequent local recurrence in the paratesticular region.
Conclusions: Spermatic cord sarcomas are rare entities that usually appear as painless paratesticular mass.
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.
Objectives: To analyze the survival rate in a series of patients with the diagnosis of renal cell carcinoma over a 19 year period based on prognostic factors usually employed in clinical practice.
Methods: Retrospective study of 259 consecutive patients with the diagnosis of renal cell carcinoma undergoing surgery in our department between 1988 and 2006. From clinical, pathological, and follow-up data we performed a survival study comparing the impact of usual prognostic factors: stage, tumor size, nuclear grade, etc.
Objective: To report one case of late metastasis of a clear cell carcinoma treated by radical surgery.
Methods/results: Patient with history of radical nephrectomy and lymphadenectomy six years before presenting with regional lymph node metastasis in a followup diagnostic test. After treatment with immunotherapy, stopped because of intolerance, surgery of the metastatic lymph node mass was decided.
Objectives: To study and review the etiopathogenic hypothesis for endometriosis and the clinical features, diagnosis and treatment of bladder endometriosis.
Methods/results: We report two cases and review the international bibliography, collecting the cases published by Spanish authors.
Conclusions: Bladder endometriosis is a rare pathological entity, but its diagnosis should be considered in fertile women with urinary tract symptoms during menstruation.
Paragangliomas or extra-adrenal pheochromocytomas account for approximately 15% of all pheochromocytomas. They are usually found in an intradiaphragmatic location. Paragangliomas of the urinary bladder are infrequent and represent 6% of the paragangliomas and 0.

Methods/results: 40-year-old female with the diagnosis of a large right retroperitoneal mass after a study for right flank pain and weight loss over several months. Surgery was performed with excision of a large tumor; the pathologic diagnosis was malignant fibrohistiocytoma.
