[Multilocular cystic renal cell carcinoma]

Multilocular cystic renal cell carcinoma is an uncommon variant recently described of renal cell carcinoma. Analyze clinicopathological features, imaging findings and prognosis and therapeutic options of this tumor. The authors reported two cases of multilocular cystic renal cell carcinoma arising in 68 and 39 year old men. They were admitted with pain in the lumbar region and/or haematuria. The imaging findings were a renal neoplasm with cystic and solid areas. The pathologic findings confirm the diagnosis of multilocular cystic renal cell carcinoma. Multilocular cystic renal cell carcinoma, usually identified at earlier stages, had slower growth rate and was therefore associated with a better prognosis and longer survival than conventionnal renal cell carcinoma

[Small cell carcinoma of the urinary bladder]

Pancreatic pseudocysts [PC] are a common complication of both acute and chronic pancreatitis. Most pancreatic pseudocysts are located within the head and the body of the pancreas, but 20%of them are extrapanereatic [pleura, mediastinum, pelvis and spleen]. The location of a pseudocyst in the liver is an exceptional event, only thirty three cases are reported in the literature. This article aimed to report a new case of PC located in the liver combined with a systematic review of reported cases published in peer-reviewed journals. A new case of PC located in the liver was reported. An extensive electronic search of the relevant literature since 1990 was carried out using Medline. We retained only the articles reporting one or several cases. When the article was unavailable, we considered the relevant abstracts which should report clinical patterns and therapeutic modalities. Reviews of the literature, systemic reviews, letters to editors and incomplete abstracts were excluded. A descriptive analysis of the collected sample including our case was performed. Morphological, therapeutic and outcome variables were reported. Tile analysis of 22 cases reported in the literature and our observation provided the following data: 17 men and 6 women with a mean age of 51 +/- 3,2 years. Seventeen patients presented an acute pancreatitis, complicating a chronic pancreatitis in seven cases, alcoholic in six cases, biliary in three cases and traumatic in one case, Six patients presented a chronic pancreatitis. The PC was located in the left lobe of the liver in 5 cases, in the right lobe in 6 cases and interested the two lobes in 5 eases. The lesion was unique in patients and multiple in 13 patients. Fifteen patients were treated by Ultrasound or CT guided percutaneous drainage. Four patients were managed surgically. Three patients had no specific treatment. One patient was successfully treated by endoscopic transpapiltary drainage. The evolution was favourable for alt patients except in three patients who died. Pancreatic pseudocyst located in the liver is an exceptional event, commonly following acute pancreatitis, rising in older male, involving the left lobe of the liver and treated by percutaneous drainage

[Histopathological study of gastric polyps. a report of 65 cases]

In a retrospective study of the specimens of gastric polypectomy, carried out between January 1992 and December 2002. we analysed the demographic and histological aspects of 65 polyps. This study revealed hyperplastic polyps in 66%, ade-nomatous lesions in 9.2%, Peutz-Jeghers polyps in 7.7%, inflammatory fibroid polyps in 6.15?, two cases of focal foveolar hyperplasia [3%]. two cases of Brunner's gland heterotopia [3%], 1 pancreatic heterotopia [1.5%], 1 fundic gland polyp [1.5%] and 1 carcinoid tumor [1.5%]. All adeno-mas and two Peutz-Jeghers polyps include intraepithelial neoplasia. Moreover, we identified a case of Brunner's gland heterotopia, which contain a focus of plane tubular adenoma with high-grade intraepithelial neoplasia. Other lesions were found within the polyps or into the surrounding gastric muco-sa, such as intestinal metaplasia and Helicobacter Pylori gastritis. This work allowed us to recommend complete removal of gastric polyps and the realization of biopsies of the non-polypoid gastric mucosa in the search of intraepithelial neo-plasia or other lesions with malignant potential
