Sarcomatoid chromophobe renal cell carcinoma revealed by acute pyelonephritis in a diabetic patient.

Chromophobe renal cell carcinoma (CRCC) is a rare tumor comprising 2 types of cells (eosinophilic and clear cells), coexisting in varying proportions. CRCC has an overall good prognosis. However, the rarely encountered sarcomatoid differentiation is associated with a pejorative outcome and must, therefore, be rigorously ruled out. Acute pyelonephritis and other infectious complications rarely occur. We report a case of CRCC with sarcomatoid differentiation in a woman in her sixties which was revealed by acute pyelonephritis and had a lethal outcome.

A case report of perineal liposarcoma.

Perineal localization of liposarcoma is extremely rare among all localization of soft tissue sarcoma. We report the case of 33-year-old man presenting a large perineal swelling. Throughout this case, we bring new insights into the surgical management difficulty of this tumor and we review the place of adjuvant therapy and prognosis factors.

[Leiomyoma of the bladder causing the destruction of a kidney]. / Léiomyome vésical entraînant la destruction d'un rein.

Leiomyoma of the bladder is a rare benign tumor deemed to have a good prognosis after surgical treatment. This is unfortunately not always true. We report the case of a 33 year-old patient who consulted for lumbar pain on right side. Exploration of patient revealed bladder floor solid tumor with non-functioning right kidney and left urinary tract dilation. Cystoscopy objectified solid tumor of the right perimeatal bladder. Tumor biopsies were performed together with the insertion of a left double J stent. Anatomo-pathologic study showed leiomyoma of the bladder. The patient underwent laparoscopic myomectomy. The postoperative course was uneventful. Pathological effect and sequelae was complete distruction of kidney.

[Testicular epidermoid cyst. A case report]. / Kyste epidermoïde intratesticulaire: a propos d'un cas.

Epidermoid cyst of the testis is a rare, begnin intratesticular tumor. Through a case report of a patient who underwent an orchidectomy, we study clinical, radiological and therapeutic aspects and particularities of this pathology.

[Endoscopic resection of benign prostatic hyperplasia in men over 80 years of age: a retrospective study of 184 cases]. / La resection endoscopique de l'hypertrophie benigne de la prostate chez les personnes ages de plus de 80 ans: etude rertospective a propos de 184 cas.

OBJECTIVE: The aim of the present study was to evaluate the outcome of transurethral resection of the prostate for benign prostatic hyperplasia in men over 80 years. MATERIAL AND METHOD: 184 men over 80 years underwent transurethral resection of the prostate for benign prostatic hyperplasia. Serious concomitant disease was found in 48.92% of cases. RESULTS: The mean operating time was 49 min ( 20 - 160mn). Others conditions found at surgery were treated during the same operation in 33.68% of cases. Peroperative complications were reported in 15 patients (8.15%) and immediate post operative complications were reported in 14 patients (7.60%), with died of 3 patients. The complications at 6 month after surgery in 172 available for followup were reported in 11 patients (6.39%). CONCLUSION: Transurethral resection of the prostate for benign prostatic hyperplasia in men over 80 years has a good outcome with an acceptable morbidity and mortality.

[Renal angiomyolipoma]. / L'angiomyolipome rénal.

Anglomyolipoma is a benign kidney tumour that may be an isolated lesion or associated especially with tuberous sclerosis. The advancement of imaging technology allows a correct diagnosis in most cases before surgery. The management approach of angiomyolipoma should be aimed at parenchymal preservation: tumorectomy, partial nephrectomy and selective embolization. However, any doubt about the diagnosis should be clarified by classic surgery.

[Ureteritis cystica. Case report and review of the literature]. / Ureterite kystique a propos d'un cas et revue de la litterature.

The authors report one case of ureteritis cystica in 40 years old women. The diagnosis was confirmed by histologic examination. The epidemiologic, etiopathogenic, radio-diagnosis and therapeutic aspects are discussed with a review of literature.

[Ureterocele in adults complicated with calculi: diagnostic and therapeutic features. Report of 20 cases]. / Urétérocèle de l'adulte compliquée de calculs: aspect diagnostique et thérapeutique. A propos de 20 cas.

STUDY OBJECTIVE: The authors study the various diagnostic and therapeutic aspects of adult ureterocele and evaluate the place of endoscopic treatment. MATERIALS AND METHODS: This retrospective study was based on 20 cases of ureterocele in adults complicated by stones and observed between January 1990 and December 2001. This series consisted of 8 men and 12 women with a mean age of 48.3 years (range: 24-75 years). The clinical features were dominated by low back pain. The diagnosis of ureterocele was based on intravenous urography in 19 patients and was discovered on endoscopy in one patient. The ureterocele affected a single ureter in 16 cases (80%) and a duplex ureter at the expense of the upper renal segment in 4 cases. All patients were treated by endoscopic horizontal meatotomy with stone fragmentation and extraction. The mean operating time was 27 min (range: 18-58 min). RESULTS: The postoperative course was uneventful in 19 patients. One patient developed postoperative sepsis. All patients were reviewed clinically and radiologically at 3 months and at 6 months. Satisfactory results were obtained in every case with no residual stones and resolution of low back pain. Only one patient presented vesicoureteric reflux which had resolved on the follow-up urethrocystography performed at 6 months. CONCLUSION: Adult ureterocele complicated by stones is a well tolerated, rare entity that can often be easily diagnosed. Endoscopic meatotomy is easy to perform and gives good results. The associated stones constitute an additional argument in favour of endoscopic treatment.
