OBJECTIVE The management of the male urethra after cystectomy for bladder cancer continues to be a dilemma. Patients who undergo a cystectomy require either urinary diversion or bladder substitution. Therefore, the use of the urethra to ensure voiding is important. On the other hand, the probable risk of urethral carcinoma recurrence is generally estimated(More)
Recently, the term ``serous cystadenoma'' has been adopted in the pathological community to qualify the so-called microcystic adenoma of the pancreas. This change in terminology was based on the emergence of a new type of serous cystadenoma of the pancreas, i.e., the macrocystic variant. We report one case of pathologically proven macrocystic serous(More)
The purpose of this study was to report the CT findings of renal cell carcinoma of clear type (RCCCT) and to determine if there are characteristic morphologic features in RCCCT with respect to tumor size, architectural patterns, and pathologic stage. The CT scans of 35 patients with RCCCT were reviewed retrospectively. The CT findings (tumor size,(More)
Forty eight patients with T1 G3 bladder cancer were treated between 1975 and 1991. An associated carcinoma in situ in one third of cases. Twenty six patients received intravesical BCG instillations (an average of 2.5 courses of 6 instillations) with no local recurrence or metastases in 50% of cases (mean follow-up: 54 months). Thirteen patients developed(More)
Use of a biological glue (GRF) is common in certain fields such as hepatic or renal surgery, but its use in vascular surgery, especially in acute aortic dissection, has not yet been reported. Our experience has demonstrated many advantages: The glue is very simple and safe to use. The aortic tissues are firmly reinforced and the sutures tighten immediately.(More)
The authors report the case of a 46-year old patient who died from fulminant herpetic hepatitis. No cause of immuno-depression was documented in this patient. No skin or mucosal herpetic lesion was found except a questionable urethritis. Herpes virus was demonstrated in the hepatocytes by electron microscopy and isolated from the serum. It was identified as(More)
PURPOSE The aim of this study was to determine if p53 status, assessed before intravesical bacillus Calmette-Guerin (BCG) therapy, can predict clinical outcome in a high risk population of patients with stage T1, grade G3 bladder cancer and if it can be used to select patients responsive to therapy. MATERIAL AND METHODS After complete transurethral(More)
Signs of glomerulopathy, especially a nephrotic syndrome can occur in cancer patients, but the exact frequency of glomerular lesions is not well known in these patients. To define this frequency in a given type of malignancy we have studied the nephrectomy kidneys in 40 patients with renal cell carcinoma. Proteinuria, which was present in 7 cases, ranged(More)
Ischemic colitis is caused by anoxia of the colonic and rectal wall due to defective regional blood supply. The pathology examination distinguishes acute obstructive and non-obstructive gangrenous ischemic colitis from chronic segmentary stenosing ischemia on the basis of the gross aspect and microscopic criteria and is necessary for differential diagnosis.(More)
