Benign cystic mesothelioma of the peritoneum (BCM) is an uncommon lesion with some 130 cases reported since the first case described by Smith and Mennenmeyer in 1979. It is a rare intra abdominal tumor occurring predominantly in women of reproductive age. Due to the rarity of this tumor, similarity of patient presentation, and comparable features on imaging, the diagnosis of this pathology is difficult, and is based on histological findings. This tumor is known for local recurrence. It's agreed that surgery is the only effective treatment, but there are no evidence-based treatment strategies for BCM.

IntroductionA solitary primary hydatid cyst in the subcutaneous abdominal wall is an exceptional entity, even in countries where the Echinococcus infestation is endemic.Case presentationWe report a case of a 70-year-old Caucasian woman who presented to our hospital with a subcutaneous mass in the para-umbilical area with a non-specific clinical presentation. The diagnosis of subcutaneous hydatid cyst was suspected on the basis of radiological findings. A complete surgical resection of the mass was performed and the patient had an uneventful post-operative recovery. The histopathology confirmed the suspected diagnosis.ConclusionHydatid cyst should be considered in the differential diagnosis of every subcutaneous cystic mass, especially in regions where the disease is endemic. The best treatment is the total excision of the cyst with an intact wall.

IntroductionA peritoneal simple mesothelial cyst is a very rare mesenteric cyst of mesothelial origin. The size of this lesion usually ranges between a few centimeters and 10 cm. It is usually asymptomatic, but occasionally presents with various, non-specific symptoms, which makes correct pre-operative diagnosis difficult. We present a case of a giant peritoneal simple mesothelial cyst that was successfully managed by complete surgical excision which is the treatment of choice.Case presentationA 21-year-old Caucasian Moroccan woman with vague abdominal discomfort and associated distention, during the previous 2 years, without other symptoms, presented to our hospital. Her past medical history was unremarkable. On physical examination, a mobile, painless and relatively hard abdominal mass was palpated. The laboratory examination and abdominal radiograph were unremarkable. Abdominal radiologic imaging showed a cystic mass of 35 × 20 × 10 cm that occupied the entire anterior and right abdominal cavity. Radical excision of the cyst was performed by midline laparotomy without any damage to the adjacent abdominal organs. The histopathological diagnosis was simple mesothelial cyst. The postoperative course was uneventful with no recurrence.ConclusionA peritoneal simple mesothelial cyst is a quite rare abdominal tumor, that must always be considered in differential diagnosis of pelvic cystic lesions and other mesenteric cysts. The treatment of choice is the complete surgical excision of the cyst.

IntroductionPrimary pancreatic hydatid cyst is extremely rare and may be a causative factor for obstructive jaundice.Case presentationA 27-year-old woman presented with obstructive jaundice, vomiting, pruritus, abdominal pain and an epigastric mass. A diagnosis of a pancreatic cyst causing a compression of the common bile buct was established by ultrasonography and CT scan before surgery. Hydatic serology was negative. The treatment consisted of the resection of the protruding dome with a drainage of the residual cavity and an omentoplasty. The recovery was uneventful and the patient has remained symptom free so far.ConclusionThe primary hydatid cyst of the pancreas may be a causative factor for obstructive jaundice and should be considered in the differential diagnosis of all cystic masses in the pancreas, especially in endemic areas.

IntroductionHematemesis caused by intragastric rupture of a splenic artery aneurysm, is an exceptional and potentially lethal emergency.Case presentationA 36 years old woman, mother of seven children presented with hematemesis. The gastric endoscopy revealed a bleeding polypoid lesion leading to a surgical management. The operative discovery of a complicated splenic artery aneurysm, led to its resection with splenectomy and gastric suture.ConclusionIntragastric rupture of a splenic artery aneurysm is an exceptional emergency which urgent diagnosis and management can avoid a potential lethal evolution.
