BACKGROUND AND STUDY AIMS There have been concerns about peritoneal seeding after endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) of mucinous pancreatic cystic lesions. The aims of this study were to determine the frequency of postoperative peritoneal seeding in patients with intraductal papillary mucinous neoplasm (IPMN) who had undergone pre-operative EUS-FNA and to compare it w...

The neurofibroma is a tumour of neural origin. This kind of neoplasm, though, is generally skin located. Rare cases in deep organs or in the peritoneal cavity are also reported in the literature. There are two types of neurofibromas, localized and diffuse; the latter is associated with von Recklinghausen disease and always occurs together with skin neurofibromas. Here we report the case of a 47...

UNLABELLED "Chylous ascites is a rare presentation of peritoneal effusion. The signet ring cell gastric adenocarcinoma is also relatively rare presentation of gastric cancer. We present a quite rare case of chylous ascites associated with signet ring cell gastric adenocarcinoma. CASE REPORT a 47-years-old Caucasian man presented to our emergency department with abdominal distention. The abdom...

Solid pseudopapillary neoplasm (SPN) is a rare malignant tumour accounting for 0.1% to 2.7% of all pancreatic neoplasms and affecting young women. Peritoneal carcinomatosis (PC) is even rarer, with only 11 reported cases. We describe a twelfth case occurring 13 years after the resection of an SPN which ruptured peroperatively. This 35-year-old woman had first undergone complete cytoreductive su...

Psammoma bodies (PBs) are observed most commonly in papillary thyroid carcinoma, meningioma, and papillary serous cystadenocarcinoma of the ovary. We report one case of peritoneal malignant mesothelioma (PMM) with massive deposition of PBs. A 72-years-old man presented with abdominal swelling and marked weight loss. Contrast enhanced computed tomography showed fluid diffuse in peritoneal recess...

Alimentary tract duplications are rare congenital anomalies. They most often become symptomatic in childhood and rarely undergo malignant transformation. Pseudomyxoma peritonei (PMP) is an equally uncommon condition, most frequently originating from a primary appendiceal mucinous neoplasm. We report an extremely unusual case of PMP arising from an intestinal duplication. A 67-year-old woman pre...

‘I'he effect of administration of cortisol on the development of plasma (eli tumors in BAL13/c mice was studied. Mice of both sexes were injected i.p. with mineral oil. Mice injected with mm eral oil alone demonstrated peritoneal lipogranuloma, hypercel lular inflammatory 8..S(ites, sustained hyperglobulinemia and high incidence of Pla@sma cell tumor development. Cortisol treated mice failed ...

Lithopedion is a rare obstetrical outcome of an undiagnosed and untreated advanced abdominal pregnancy, mostly found incidentally. We present a case of lithopedion. In a 76 year-old female suffering from cervical neoplasm, total abdominal hysterectomy was performed for the lesion and the lithopedion was found incidentally. The patient's history was unremarkable, and laboratory tests were normal...
