RESUMEN
The authors report one case of vesical paraganglioma, not suspected in a 50-years-old female patient who presented gross hematuria as only symptom. The patient was not hypertensive. Radiologic and endoscopic investigations revealed a trigonal submucosal tumour. Complete transurethral resection of the tumor was performed with no intraoperative complications. The histopathological diagnosis indicated pheochromocytoma. Blood pressure was stable. There has been no recurrence for 18 months after transurethral resection.

We report our experience with treating the vaginal aplasia by vaginoplasty used sigmoid graft in about three cases. Two patients presented with the Rokitansky-Kuster-Hauser syndrome and one a gender reassignment for intersex. Anatomic and functional results were satisfactory with no vagina stenosis. All three are sexually active. The sigmoid colon is the best choice for interposition vaginoplasty.

Inflammatory pseudotumors are benign neoplasms associated with local or general manifestations. Renal localisation seems exceptional, the etiology is unknown. The article raises the question of the problem in establishing a preoperative definitive diagnosis, as a correct diagnosis is often only confirmed following nephrectomy.

The authors describe a case of enterovesical fistulas in a patient with Crohn's disease that presented exclusively as urinary symptoms manifesting as bladder tumor. Ultrasound examination showed a normal upper urinary tract and a bladder tumor. Cystoscopy examination revealed a bladder tumor at the retrotrigonal region without showing the fistula orifice. Transurethral resection of the tumor revealed an inflammatory pseudotumor of the urinary bladder at the results of histological studies. Magnetic resonance imaging showed a normal upper urinary tract but a bladder tumor and a sigmoidovesical fistula. The results of barium contrast studies established the presence of numerous enterovesical fistulas. Partial resection of the ileum, ileostomy, colostomy and suture of the bladder fistulas was performed. Histological diagnosis of the affected ileum was Crohn's disease. The clinical features, natural history and treatment of enterovesical fistula secondary of Crohn's disease were discussed.

Renal oncocytoma represents a rare benign tumor accounted for 3-5% of renal neoplasms. It has been mistaken for and mistabled as granular or dark cell carcinoma. Between 1993 and 1998, 3 women with renal oncocytoma were recognized at formation and underwent radical nephrectomy. Sonography and the CT scan was performed but the Accurate diagnosis was not possible before performing surgery and histologic investigations. The mean Follow-up of 3 patients was 48 month and showed a benign clinical behaviour in all cases.

Inflammatory pseudotumor is a reactive benign lesion which can be very difficult to distinguish from some malignant bladder tumors like sarcomas or sarcomatoid carcinoma. Inflammatory pseudotumour (IPT) of the urinary bladder is a benign proliferate lesion which can simulate clinically and histologically a sarcoma. A case of an inflammatory pseudotumor of the urinary bladder in a 18-years-old man is presented. This patient presented with sudden onset of gross painless hematurial related to large polypoid and ulcerated bladder masses found on endoscopy. Initial pathological analysis was interpreted as rhabdomyosarcoma but subsequent reviews were consistent with a benign process resembling nodular fasciitis. This rare, benign and presumed non-neoplastic, reactive lesion must be differentiated from sarcomas of the urinary bladder. Immunohistochemistry seems to be the method of election in differentiating inflammatory pseudo-tumor from other spindle cell proliferations of the bladder. When diagnosis is certain, complete transurethral resection is the treatment of choice. However, if there is no total pathologic confirmation, if it is a very wide lesion or if it is recurring after endoscopic resection, a partial cystectomy is suggested.

The author reports a serie of 4 cases of male urethral diverticulum. All cases were acquired origin. They are complication of urethroplasty. Diagnosis is clinical, based on the development of a perineal mass or phlegmon. This diagnosis is confirmed by cystourethrography. Treatment is by open surgery and consists on diverticulectomy and repair urethra in one stage. Two steps are necessary as the reported cases, where they are urethral stenosis or a inflammatory involvement of the peridiverticulum tissues. This treatment achieves good results.

Adenocarcinoma of urethra is a rare tumour, which occurs more often in female than in male. The localizations on bulbomenbranous urethra, most frequent, have worse prognostic than those of penile urethra. Because of scarcity of these tumours there is not therapeutic consensus. The treatment is based on the tripod surgery, more or less mutilating, chemotherapy and radiotherapy associated or managed in a separate way. We report the case of a young patient with adenocarcinoma of the posterior urethra treated by a protocol of radio-chemotherapy.

This case report describes a 53-year old man with Cushing's syndrome due to Adrenocorticotropic Hormone (ACTH) independent bilateral adrenocortical macronodular hyperplasia (AIMAH). His plasma cortisol showed no diurnal rhythm and was unsuppressable by high-dose dexamethasone. Plasma ACTH was undetectable and did not respond to corticotrophin-releasing hormone. The aetiology of this rare disease remains uncertain. The treatment is based on bilateral adrenalectomy.

Sarcomatoid carcinoma of the kidney is an uncommon tumor associated with a very poor prognosis. Because this tumor can be occasionally difficult to distinguish from renal sarcoma, immunohistochemistry and electronmicroscopy are sometimes necessary for diagnosis. Therapy is actually essentially surgical because if adjuvant therapies should follow radical nephrectomy, no standardized regimen has been at present defined.

UNLABELLED: Detrusor-sphincter dyssynergia is responsible for major impairment and is factor for social and professional activity repercussions. METHODS: We have studied the clinical and urodynamic finding in four patients (two men and two women) with detrusor-sphincter dyssynergia. Mean age is 36 years (26-44 years). Dyssynergia was secondary to tuberculosis meningitis in one case, surgery for rectal adenocarcinoma in one case, tight vertebral canal in one case and in one case the cause is indeterminate. The detrusor-sphincter dyssynergia were treated by autocatheterism in two cases, antibiotherapy antituberculosis associated with an anticholinergic drugs in one case and by alpha-blockers agent in another. RESULTS: Quasi-complete salvage of the motor deficit and the dysfonctional voiding in a patient treated by antibiotherapy antituberculosis associated with an anticholinergic drugs. As well, maid evolution in patient treated by alpha-blockers agent and who practice self catheterization. CONCLUSION: Optimal treatment is unknown, and the existence of several cures indicated the limit of all therapeutic methods.

We report a new case in a 56 years old patient who manifested right side's pains. The abdominal CT scan showed a tumor of the right adrenal gland with fat density (size: 8 x 6 x 6 cm). This tumor was removed surgically (weight: 300 g). The histological finding revealed a proliferation of adipocyts and myeloid tissue which contains megakaryocytes, erythroid cells and lymphocyts. The outcome is good after three years of surgery. The surgical treatment becomes necessary when the tumor's size increases or it becomes symptomatic.

DEFINITION: Clear cell sarcoma of the kidney was initially thought to be a variant of Wilms tumour with an unfavourable prognosis. METHODS: A 23 years-old woman presented with a right abdominal mass. CT scan revealed a solid 23 cm tumour of the right kidney. A right radical nephrectomy with retroperitoneal lymph node dissection was accomplished. The histological diagnosis was clear cell sarcoma. A combination chemotherapy regimen (cisplatin and doxorubicin) was performed on six cycles. RESULTS: After two years, there was no evidence of tumour in the abdomen and thorax on CT Scan. The patient is being well. CONCLUSION: Optimal treatment is unknown, and surgery, radiotherapy and chemotherapy are used alone but mostly in combination.

We report one case of neuroendocrine tumour of the prostate in a 74 years old patient. The clinical symptomatology was dominated by pollakuria, dysuria. Digital rectal examination showed a bulky prostate, hard and irregular. The rate of PSA was high (23 ng/mL). The endorectal ultrasonography revealed a pelvic heterogeneous mass depending of prostate. The biopsy showed an adenocarcinoma of prostate. The patient underwent a transuretral resection of the prostate (TURP) and pulpectomy. Histology and immunohistochemistry through antibody anti NES and antibody antisynaptophysin of shavings of resection revealed a neuroendocrine tumour of the prostate. Twelve months after, the lung X-ray, abdominal ultrasonography and bone scintigram was normal. The rate of PSA was 2.1 ng/mL.
