[Hypoglycemic coma revealing a solitary fibrous tumor of the pleura].

INTRODUCTION: Solitary fibrous tumor of the pleura (TFSP) is rare. When associated with hypoglycemia it is commonly referred to as Doege-Potter syndrome. CASE: A 51-year-old man was hospitalized for recurrent near-syncope associated with hypoglycemia. Clinical examination and then thoracic imaging clearly showed anomalies that corresponded to a mass occupying the entire left hemithorax. After resection, histological analysis diagnosed a fibrous tumor of the pleura. DISCUSSION: Solitary fibrous tumors of the pleura are observed most often in patients aged 50 and 70 years. Hypoglycemia is rare, occurring in approximately 4% of cases. It is explained by the abnormal secretion of a type-II insulin-like growth factor. This tumor is treated by complete surgical excision.

[Solitary fibrous mediastinal tumor. A case report].

Solitary fibrous tumor is a rare tumor, generally located in the pleura. Recently, new sites have been described in the literature, particularly involving the peritoneum and mediastinum, as wekk as te-the bronchopulmonary and orbital regions. The diagnosis is established at pathology, but in some cases may be difficult to differentiate from other tumors. We report the case of a 60-year-old women who had undergone surgery 25 years ago for right pulmonary hydatid cyst and who presented inspiratory dyspnea and dry cough for four months. Physical examination revealed a right cervical tumefaction in the supraclavian region. The AP chest x-ray disclosed an opacity in the right laterotracheal upper cervicomediastinal zone laminating the trachea which was displaced to the left. Thoracic computerized tomography showed a tissular process in the superior and middle mediastinum. Surgical tumor resection was performed and pathology confirmed the diagnosis of solitary fibrous tumor. The postoperative period was uneventful. Frequency of the mediastinal localisation is the same in men and women. The tumor generally develops between the 5th and 7th decades, and is most often asymptomatic. Fortuitous discovery is the rule. The clinical course is unforeseeable.

[Abdominal stab wound injury with omentum evisceration].

INTRODUCTION: The abdominal stab wound with omentum evisceration, represent 4 to 20% of abdominal injuries. It causes a problem of therapeutic indication between selective and mandatory laparotomy. The goal of this work is to give some answers to this dilemma. MATERIAL AND METHODS: A retrospective study from 1992 to 2000, concerning 75 patients presenting an omentum evisceration. Where there were 71 men et four women, the mean age was 25 years old. All the abdominal injuries are exclusively by the stab wound. These 75 patients were divided into three groups: group I: 24 patients (32) were immediately operated ahead of the existence of severity elements; group II: 18 (24%) patients had an isolated omentum evisceration without any elements of severity were operated immediately; group III: 33 (44%) were placed under clinical, radiological and ultrasound control. RESULTS: We have found four cases of negative laparotomy (16,7%) in group I, and 14 (77,8%) in group II. Five secondary laparotomies (15%) were performed in group III. Among the 51 patients (Group II and Group III) nine (17%) had visceral injuries... In all of the three groups, there was a high frequency of intestinal organs injuries, there was no mortality and 12% of morbidity. CONCLUSION: The isolated omentum evisceration is a penetrating injury of the abdominal wall but not synonym with visceral injuries, the interventionists authors had a high rate of negative laparotomy. However the selective authors in the asymptomatic patients under clinic examination appears logical: we believe that the laparoscopic diagnostic and therapeutic in doubtful cases can resolve this problem.

[A rare and benign etiology of Pancoast-Tobias syndrome].

Although lung cancer is the leading cause of Pancoast-Tobias syndrome, benign etiologies have been rarely described in the literature. We report two cases of Pancoast-Tobias syndrome caused by hydatidosis of the apex. Outcome was favorable after surgical treatment.

[Larrey or Morgagni hernias treated by laparoscopy].

INTRODUCTION: Diaphragmatic hernia or Morgagni-Larrey hernia is a rare entity. Its treatment is surgical and hence raises the question of the surgical approach. OBSERVATIONS: Two patients underwent laparoscopic surgery for Morgagni-Larrey hernia. The first, aged 17 exhibited a chromosomic abnormality (trisomie 21). The second was 18 years old. Both patients underwent surgery by laparoscopy. In both cases, the surgical act performed was resection of the hernia and closure of the orifice with separate sutures. Their post-surgical courses were uneventful, even two years later. COMMENTS: In the age of mini-invasive surgery, laparoscopy is an excellent alternative to laparotomy in this benign pathology.

[Hydatid cyst of thoracic soft tissues].

Hydatid cysts are uncommon in thoracic soft tissue. We report a case of hydatid cyst which had developed within the lattissimus dorsi presenting as a left parietal scapular mass diagnosed by ultrasound and CT scan, which remains the preferred primary examination for the investigation of masses of this type. We discuss the various possible clinical and paraclinical contexts and recommend total pericystectomy of a closed cyst as the best treatment for this kind of cyst.

[Serous fibrinous pleurisy disclosing hydatid cyst of the liver fistulizing into the pleura].

Hydatic cyst of the liver remains a serious public health problem in Morocco and several other Mediterranean countries. This benign affection can cause serious sometimes fatal complications such as cyst rupture into the biliary ducts or the thorax. We present the case of a patient with serofibrous pleurisy and recall the often late diagnosis of hydatic cyst. Biliary pleural fistulization is a rare but serious complication.

[Malignant mediastinal schwannoma in Recklinghausen's disease presenting as cardiac tamponade. Report of two cases].

The authors report two cases of Recklinghausen's disease admitted for cardiac tamponade. Two-dimensional echocardiography showed a pericardial tumour in addition to a compressive pericardial effusion. After pericardial drainage, the outcome was rapidly fatal. Histological examination confirmed the diagnosis of a malignant intrapericardial schwannoma. A review of the literature revealed the scarcity of mediastinal malignant schwannoma. Associated with Von Reckinghausen's disease in 2 to 13% of cases, the prognosis is poor. The presentation of malignant mediastinal schwannoma with cardiac tamponade remains very rare.

[Pancreatitis of hydatid origin].

INTRODUCTION: Hydatic cysts of the liver are known to rupture into the biliary tree, but acute pancreatitis is an uncommon consequence. CASE REPORT: A 30-year-old woman who had undergone cholecystectomy 8 years earlier for gall bladder stones was hospitalized because of acute abdominal pain. Acute pancreatitis was diagnosed. Abdominal sonography showed a hydatic cyst. Fifteen days after admission after normalization of the amylasemia, surgical cure was successful. DISCUSSION: This case demonstrates that hepatic material can migrate via the main bile duct and provoke acute pancreatitis. Fistula drainage via the Oddi sphincter can be successful.

[Cancer of the gastric stump].

Among a series of 266 cases of gastric cancer operated on between 1981 and 1991, 8 cases were developed on gastric stump after gastro-duodenal surgery. A post operative delay of 10 years has been insisted upon. We note an exclusive masculine series. The main age was 61 years. Clinical aspects were univoque and treatment was always surgical with a resecability rate of 37%. Pathological analysis of operatory specimen and biopsies has shown everywhere an adenocarcinoma. The only way to improve the prognosis and to lay the live based on the yearly histoendoscopic supervision since the tenth year after initial intervention of these operated patients of the stomach with high neoplastic risk.

[Hydatid cyst of the psoas muscle].

Hydatid cysts in the psoas muscle are unusual. The authors report a case of a hydatid cyst which had developed within the psoas muscle and was detected from a mass in the left iliac fossa which was diagnosed before surgery by ultrasound and a CT scan, which remain the preferred primary examinations for the investigation of masses of this type. The authors discuss the various possible clinical and paraclinical contexts and recommend total pericystectomy of a closed cyst as the best treatment following extraperitoneal iliac surgical opening.
