[Acute occlusion with fever in a Tunisian woman]. / Syndrome occlusif fébrite aigu chez une tunisienne.

The purpose of this report is to describe a case of idiopathic segmental infarction of the great omentum, in a Tunisian woman, who presented with acute right hypchondrial pain simulating cholecystitis. Abdominal CT scan is the modality of choice. If symptoms resist medical treatment or complications occur, laparoscopic excision is the best therapeutic technique.

[Cystic lymphangioma of the pancreas: an exceptional location]. / Lymphangiome kystique du pancréas : une localisation exceptionnelle.

Cystic lymphangioma of the pancreas is a rare benign vascular tumor. Its histogenesis is still hypothetical and preoperative diagnosis is difficult. We report a new case in a 14-year-old girl hospitalized for pain in the epigastrium and vomiting. Radiologic findings concluded in a cystic tumor of the head of the pancreas. The mass was completely excised. The pathological examination of the surgical specimen revealed cystic formations whose wall consisted of a squamous endothelial epithelium on a fibrous tissue and a few scattered lymphoid clusters, arguing in favor of a cystic lymphangioma.

[Intrauterine device and pelvic tumor: two case reports of pelvic actinomycosis with pseudotumor from tropical zones]. / Dispositif intra-utérin et tumeur pelvienne: 2 observations sous les tropiques d'actinomycose pelvienne pseudotumorale.

Pelvic actinomycosis is a rare chronic disease caused by actinomycete species. The pseudotumorous form is the most common and often leads to misdiagnosis. The purpose of this report is to describe two cases of pelvic actinomycosis involving women with a history of intrauterine contraceptive device (IUD) use. Diagnosis was based on pelvic mass and the findings of surgery undertaken for suspicion of an advanced ovarian tumor with hepatic metastasis in one case and for a tumor of the right ovary in the other case. Diagnosis was confirmed by histological examination of a biopsy specimen in the first case and of the surgical specimen (right ovariectomy) in the second case. Long-term antibiotic therapy was effective in both patients. Based on these two cases and review of the literature, discussion focuses on diagnostic pitfalls, natural course, and therapeutic options for this particular infection.

[Intestinal perforation in a Tunisian woman: peritonitis due to a fishbone]. / Un coup de poignard abdominal chez un tunisien: péritonite par arête de poisson.

Diagnosis of foreign body perforation of the gastrointestinal tract can be difficult. The purpose of this report is to describe a case of acute peritonitis after perforation of the ileum by a fish bone that was detected by computed tomography.

[Pelvic pseudotumoral actinomycosis: two cases]. / Actinomycose pelvienne pseudotumorale : à propos de deux cas.

INTRODUCTION: Pelvic actinomycosis is a rare suppurative disease that should be included in the differential diagnosis of gynecological cancers. CASE REPORTS: We report two women aged 40 and 41 years with pelvic tumor-like actinomycosis. Physical examination disclosed a pelvic mass in both cases. CT-scan showed annexial infiltrative tumor in both cases with liver metastasis and peritoneal carcinosis in one case each. Surgical procedure consisted in right annexectomy in one case and peritoneal biopsy in the other. Pathologic diagnosis was diagnostic of actinomycosis. Both patients were treated by penicillin G 20 million IU/day during two weeks and then by amoxicilline 3g/day per day during six months. Clinical outcome showed significant improvement in both cases with complete regression of hepatic and pelvic lesions on CT-scan in one case. CONCLUSION: Pelvic actinomycosis is a rare suppurative disorder, commonly associated with a long term wearing of intra-uterine device. Diagnosis is difficult, often delayed and pelvic actinomycosis could mimic gynaecologic neoplasia.

[Two pelvic tumors which should not be operated, lymphoma of Burkitt and actinomycosis]. / Le lymphome de Burkitt et l'actinomycose, deux tumeurs pelviennes qu'il ne faut pas opérer.

The treatment of the pelvic tumors depends of their histological nature. Some of them require only one medical treatment without recourse to surgery. We report two rare cases of pelvic tumors occurring in young adults. For the first case, actinomycosic nature was related to the histological study of the surgical biopsies. Concerning the second case, the lymphatic nature of a tumor of the low rectum was retained on the immunohistochimic study of the endoscopic biopsies. The evolution was uneventful in the two cases after a medical treatment containing penicillin G or a chemotherapy. We discuss at the time of these two observations the diagnostic difficulties and the therapeutic methods of these rare affections.

[Severe rectal bleeding in an Tunisian woman: colonic tuberculosis mimicking a tumor]. / Une rectorragie sévère sous les tropiques.

Since colonic tuberculosis is uncommon and its bifocal pseudo-tumor form is exceptional, differential diagnosis with the colonic cancer is exceedingly difficult. The purpose of this report is to describe a case of primary colonic tuberculosis in two separate locations discovered in a patient presenting with persistent massive hematochezia. A 69-year-old woman was examined for hematochezia, abdominal pain and recent weight loss. Colonoscopy revealed the presence of two ulcerated tumor-like lesions in right colon. One of these lesions caused significant stenosis. Histological examination of biopsy specimens was inconclusive. Colonic tumor with bleeding was considered as the most likely diagnosis. Surgical exploration demonstrated one tumor in the cecum and another in the ascending colon. Right hemicolectomy was performed. Histological examination of the surgical specimen demonstrated a granulomatous reaction pattern with caseous necrosis. Conventional antituberculosis treatment led to clinical improvement.

[Fatal postoperative crisis in acute hereditary porphyria]. / Crise post-operatoire fatale d'une porphyrie aiguë héréditaire.

The acute porphyria is an autosomal dominant disorder of the héme biosynthesis enzyme. The aim of this work is to determin a diagnostic step in order to anticipate porphyric crises. We report the observation of a child which was hospitalized in the pédiatric service three years ago for peripheric arthralgies and myalgies where the diagnosis of an acute porphyria was not posed. He wase admitted in our service for appendicitis, he was operated, the anesthesie was carried out by the thiopenthal and the succinylcholine. At the first post-operative day, a respiratory insufficiency was the cause of death. The rate of coproporphyrines and of uroporphyrines in the urine had confirmed the diagnosis of acute porphyria. The positive diagnostic of acute porphyria is difficult, the association of abdominal, psychological and neurologic signs must suggest the diagnostic, all the more, if the urines have a dark colour. The presence of uroporphyrines and coproporphyrines and certain precursors in the urines or in the high-rated stools confirm the diagnostic. The family survey and dosage of porphyric compounds in the sickness-bearing patient's family members allow to reveal certain asymptomatic forms of the heriditary acute porphyria, it is caused by certain products used in neuropsychiatry, in aneasthesic or in certain circunstances, such as, the infection or the trauma. The treatment of the acute porphyria is an emergency wich requires the transfert of the patient to a unit of intensive care.
