A 37 year old-woman complained about persistant pain of right abdominal quadrant. We discovered many hepatic lesions. Histology revealed benign processus. Evolution was marked by peritoneal carcinomatosis. After reexamination of histology we discovered hepatic haemangioendothelioma. The patient died 18 month after diagnosis although chemotherapy.
A 47-year old man complained about persistant pain and cholestasis 12-years after a cholescystectomy. In his family, all his brothers and sisters had cholecystectomy. Genetic explorations revealed a MDR3 gene mutation. All symptoms disappeared with a treatment by ursodesoxycholic acid. MDR3 gene mutation is to be researched in all cases of familial cholestasis.
A patient underwent at his birth, an ureterosigmoidostomy for exstrophic bladder. Fifty-six years later, she presented a carcinoma on the right ureterosigmoidostomy associated with chronic urinary infection. She underwent a right ureteronephrectomy and sigmoidectomy. Chronic alterations of the colic mucin by urines lead to carcinoma.
We herein report five cases of heterotopic pancreas localized on common bile duct, gastric antrum, duodenum (two cases including one with cystic dystrophy), and jejunum. The choledocal localization was revealed by jaundice. The duodenal localization with cystic, diagnosed by endoscopic ultrasound, was revealed by onsets of acute pancreatitis. All localizations were treated by resection: antrectomy, bowel resection, and pancreaticoduodenectomy. Postoperative course was uneventful. Review of the literature shows that, even in uncomplicated cases, resection is usually performed.
An 80-year-old woman with sigmoïd diverticula was treated by corticosteroid for Horton disease. She presented abdominal pain, and abdominal mass in left iliac fossa. Radiological examinations revealed a colo-jejunal fistula. At laparotomy it was a giant diverticulum of colon sigmoid with fistula in the jejunum. The pathogeny of giant diverticulum and the role of corticosteroid are discussed.
We report the case of a patient who underwent splenectomy for spontaneous rupture of the spleen due to splenic metastasis. Pathologic examination revealed diffuse infiltration by carcinoma. Chest X-ray revealed a right lung superior lobe tumor, related to poorly differentiated carcinoma. Total splenectomy is a good option for diagnosis and treatment of splenic metastases.
We herein report a case of axillary localization of supernumerary breast. It is a matter of axillary bilateral masses mistaken as lipoma at clinical examination and ultrasonography. We here explain this confusion between lipoma and supernumerary breast. The aim of this work is to specify clinical characters of an axillary mass that must lead to suspect a supernumerary breast.
We report a case of postoperative inferior mesenteric arteriovenous fistula. Arteriovenous fistula represents a rare disease. Symptoms are due to portal hypertension and distal ischemy. Treatment of these fistulas is embolization. Surgery is possible by ligature or excision of the fistula because vascularisation is obtained by Riolan arcade and hypogastric artery.
The cecum is the second most common site of colonic volvulus after the sigmoid. The mechanism is torsion or hyperflexion of the enlarged, poorly-fixed, and hypermobile cecum. It presents clinically as an acute bowel obstruction with strangulation. Diagnosis can be made by plain abdominal X-ray in more than half the cases on the basis of cecal distention (with a classical "teardrop" or "comma" appearance), proximal small bowel distention with air-fluid levels, and a gasless distal colon. Barium enema shows lack of filling of the cecum, often with a "beaked" termination of the column of contrast. CT images are pathognomonic when they reveal a cecal "vortex". After surgical reduction of the torsion, ileo-cecal resection is usually the best therapeutic alternative. Cecopexy may be aDDrouriate in older and debilitated Datients if there is no concomitant cecal necrosis.
