[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

Prognostic value of the immunohistochemical expression of: KI67, p53, pcna and bcl2 in the superficial tumors of the bladder

To study a serie of superficial tumors of the bladder and to assess the prognostic significance of p53, Ki67, PCNA and bc!2 in these tumors. We studied 59 bladder tumors: 43 pTa and 16 pTl. All Patients had cystoscopy 3 months after the resection and tumors that did not recur had a minimum follow up of 5 years. Age more than 65 years [p = 0,001], multifocality [p=0,022] and tumoral size > 3 cm [p = 0,022] were correlated with the recurrence. The expression of p53 was correlated with the recurrence in the year following the tumoral resection [p = 0,035]. That of of Ki67 was correlated with the histological grade [p = 0,03] and stage [p=0,002]. Our results suggest to practise regular endoscopic controls during the first year following the resection of the primitive tumor if it expresses p53. The immunohistochemical expression of Ki67 being correlated with the grade, this marker could help to better classify the tumors of intermediate grade

[Pelvic ganglioneuroma. Report of a case]

Ganglioneuroma is a rare benign tumor. It is the most mature of neurogenic tumors. We report a case of a pelvic ganglioneuroma diagnosed in 24-year-old pregnant women who presented with an urinary infection. Echographic examination suggested an ovarian mass. At surgical operation, the tumor was close to the sacrum. A total resection of the tumor was performed. Pathological examination proved it as a ganglioneuroma. Sixteen months later, the patient is free from disease
