[Sarcomatoid carcinoma of the bladder with major osseous metaplasia]. / Carcinome sarcomatoïde de la vessie avec métaplasie osseuse majeure.

The authors describe a case of sarcomatoid carcinoma of the bladder, in which the stroma presented marked calcified bone metaplasia. Mechanical lithotripsy of the tumor was necessary to allow transurethral resection.

[Reduction of the weight of prostatic tissue during transurethral resection]. / Réduction de poids du tissu prostatique au cours de la résection transurétrale.

OBJECTIVE: To study the weight reduction of prostatic tissue removed during transurethral resection. METHOD: 22 hyperplastic prostate glands enucleated via a transvesical approach were resected in vitro, under conditions as close as possible to in vivo resection in 11 cases. The authors compared the weight of the enucleated prostates with the weight of fresh resection chips and the weight of chips fixed in Bouin solution. RESULTS: The weight of the chips was 28% lower than that of the prostates, while the weight of chips fixed in Bouin solution was 8% higher than that of the fresh chips. CONCLUSION: Transurethral resection causes a 28% loss of the weight of resected prostatic tissue and fixation in Bouin solution of these same chips increases their weight by an average of 8%.

[Kidney varices: an unusual location]. / Varices rénales: une localisation inhabituelle.

The authors report the case of a 40-year-old woman who presented with very large right renal varices. Computed tomography and arteriography showed that these varices were situated on the convex surface of the kidney, in front of its anterior surface, and drained venous blood derived from the renal parenchyma. These varices were probably secondary to undiagnosed renal vein thrombosis.

[Pseudotumoral xanthogranulomatous pyelonephritis. A propos of 2 cases]. / Pyélonéphrite xanthogranulomateuse pseudotumorale. A propos de deux cas.

We report two cases of xanthogranulomatous pyelonephritis observed in elderly women. Diagnosis before surgery is difficult. CT is the best single examination.

[Emphysematous pyelonephritis. A case medically treated]. / Pyélonéphrite emphysémateuse. Un cas traité médicalement.

Authors report on a case of emphysematous pyelonephritis in a woman affected with diabetes and renal failure. In order to avoid chronic dialysis, no nephrectomy was performed and the patient was treated only with drugs. Full recovery was obtained, without worsening of the renal function.

[Ureteral stenosis caused by pelvic actinomycosis]. / Sténose urétérale par actinomycose pelvienne.

The authors report a case of pelvic actinomycosis causing ureteral obstruction in a 30-year-old woman. An intra-uterine device being in place for 6 years is considered as the main cause. The treatment, which included a laparotomy for abscess drainage, an indwelling double pigtail ureteral stent and a 9 month antibiotherapy led to recovery after an initial relapse.

[Colonic adenocarcinoma after Coffey's operation. A case]. / Adénocarcinome colique après intervention de Coffey. Un cas.

The authors describe a case of colonic adenocarcinoma in an 41-year-old woman who had undergone at age 3 an uretero-colic anastomosis because of bladder exstrophy. The tumor looked like an ovarian tumor and histology confirmed it was a Krûckenberg tumor of colonic origin. The authors review literature and insist on the necessity of a life long endoscopic follow-up of uretero-colic anastomosis.

[Pseudotumoral thoracic actinomycosis with lung and brain metastases. Apropos of a case. Review of hundred thirty one cases in the literature]. / Actinomycose thoracique pseudo-tumorale avec métastases pulmonaires et cérébrales. A propos d'un cas. Revue de cent trente et un cas de la littérature.

One particular case of thoracic actinomycosis is reported. The patient presented with a neurological picture mimicking a metastasis, as chest radiogram and CT-Scan indicated a primary pulmonary tumor. Diagnosis of actinomycosis was overlooked and final diagnosis was based on direct microscopy of lung tumor, which required a thoracotomy, without any resection. Antibiotic treatment with penicillin was successful as the cerebral lesion was completely cured within 2 months and the thoracic lesion reduced 2/3rd volume within the same delay. The importance of correct handling of tissue specimens and adequate informations to the microbiologist are emphasized. Another point of interest is that good clinical results can be expected from prolonged antibiotic treatment. Surgery must be reserved for diagnosis if no other means has been effective, for failure of medical treatment or for acute complications.
