[Bladder leiomyomas.].

Unlabelled: Bladder leiomyomas are rare benign tumors; their common presentation are irritative and obstructive urinary symptoms. The treatment is complete surgical resection.

Objective: To present our experience in the diagnosis and the treatment of bladder leiomyoma.

Testicular adrenal rest tumors.

We report a case of congenital adrenal hyperplasia in a 29 year old patient, who presented with testicular pain, bilateral testicular masses, and oligospermia. Ultrasonography confirmed, in both testis, the presence of heterogeneous and hypoechoic lesions with irregular borders and internal and peripheral vascularization. Seric tumor markers were negative.

Tubulocystic renal carcinoma (low grade collecting duct carcinoma).

Objective: To report a case of tubulocystic renal carcinoma diagnosed in an adult, after a work up study for hematuria.

Methods/results: 59-year-old male, CT scan was performed during a study for self-limited hematuria showing a 4.2 cm solid mass with areas suspicious of pseudocystic malignancy.

Adrenal ganglioneuroma.

Objective: To present one case of adrenal ganglioneuroma incidentally diagnosed in an adult.

Methods/results: 44-year-old woman with a 2.3 cm incidentaloma in the left adrenal gland diagnosed by CT scan.

Neuroendocrine carcinoma of the urinary bladder. 15-year retrospective analysis.

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.

Vesical nephrogenic adenoma: an unusual presentation of a bladder tumour.

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.

Metastasis to the tunica vaginalis testis from a primary mucinous tumor of the cecum.

Objectives: We review the literature about secondary testicular tumors.

Methods: We present the case of a patient with a metastatic mucus-secreting testicular tumor who presented in the emergency room with symptoms of acute scrotum 10 months after surgery for a mixed tumor of the cecum. This type of tumor is rare, and the treatment of choice is orchiectomy; nevertheless, the prognosis of such metastasis remains poor.

[Bilateral synchronic testicular tumour of different histology].

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.

[Bellini duct carcinoma: report of two cases].

Objective: We report two cases of collecting duct carcinoma that were diagnosed in our hospital in a six-month period.

Methods/results: The first case was a 75years-old woman showing in CT scan a mass in the left kidney which infiltrated perinephric fat. The second case was a 72-years-old that showed in a CT scan a right renal pelvis lesion, involving inferior vena cava and renal vein.

Implications of p53 gene mutations on patient survival in transitional cell carcinoma of the bladder: a long-term study.

Objective: To determine the prognostic value of p53 gene mutations and P53 overexpression for predicting the incidence of recurrence, progression and long-term survival of patients with transitional cell carcinoma (TCC) of the bladder.

Methods: Prospective cohort study with 94 consecutive patients diagnosed and treated for TCC. DNA was obtained from tumor tissue to perform PCR-SSCP of p53 exons 5-9, with automatic sequencing of any mutated samples.

Sensitivity and specificity of p53 protein detection by immunohistochemistry in patients with urothelial bladder carcinoma.

Objective: To analyze the correlation between the genotypic and phenotypic patterns of p53 in patients with transitional cell carcinoma (TCC) of the urinary bladder.

Materials And Methods: Cross-sectional study of 73 patients diagnosed with TCC. DNA was obtained from the tumor tissue to perform polymerase chain reaction-single strand conformational polymorphism (PCR-SSCP) of exons 5-9 of the p53 gene, with automatic sequencing done on any mutated samples.

Update on the diagnosis and treatment of bladder endometriosis.

Bladder endometriosis is rare, although the bladder is the urinary tract structure most often affected by this condition. The common clinical manifestations of bladder endometriosis include menouria and urethral and pelvic pain syndrome occurring cyclically. Imaging methods are not conclusive for the definitive diagnosis.

Paraganglioma of the bladder: controversy regarding treatment.

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.
