1/5. Multilocular peritoneal inclusion cyst with extensive xanthogranulomatous stromal changes: a differential diagnosis of cystic pelvic tumors in women.This report presents an unusual case of multilocular peritoneal inclusion cyst with extensive xanthogranulomatous changes in the cyst stroma occurring in a 21-year-old woman. The multicystic tumor was found attached to the mesentery of the terminal ileum. Microscopically, the cystic spaces were lined by flattened to cuboidal cells, which displayed immunoreactivity for cytokeratin but not for factor viii-related antigen. Large stromal areas contained cholesterol clefts, multinucleated foreign body giant cells, and accumulations of foam cells. The pathogenesis of this multilocular peritoneal inclusion cyst remains obscure. The patient is disease-free 10 years after surgery. The most important differential diagnosis to this case is mature cystic teratoma of the ovary with xanthogranulomatous changes.- - - - - - - - - - ranking = 1keywords = cell (Clic here for more details about this article) |
2/5. Mesenteric cysts in children.Mesenteric cysts are rare intraabdominal lesions of childhood that may vary in presentation from an asymptomatic mass to an acute abdomen. From 1970 to 1990, 15 children were diagnosed and treated for mesenteric cysts at Ste Justine Hospital in Montreal. The ages ranged from birth to 18 years (average age, 6 years). There were 9 boys and 6 girls. Ten patients required emergency surgery and five underwent elective surgery. The main presenting symptom was abdominal pain. Ten patients had preoperative ultrasounds that were diagnostic for a cystic mass in all patients. The second most frequent preoperative diagnosis was appendicitis. The cysts were located in the small bowel mesentery in 5 cases, the base of the mesentery with retroperitoneal extension in 4 cases, the transverse mesocolon in 4 cases, and the gastrocolic ligament in 2 cases. Operative procedures performed included complete cyst excision (9 patients), complete excision with intestinal resection (5 patients), and drainage of the cyst (1 patient). The only recurrence in this series occurred after drainage. One other patient had recurrence of a mesenteric cyst following resection performed elsewhere. Mesenteric cysts are rare in children, are usually symptomatic, and are most commonly misdiagnosed as acute appendicitis. Accurate preoperative diagnosis is possible with current ultrasonographic imaging techniques. Complete cyst resection is the procedure of choice and results in an excellent outcome.- - - - - - - - - - ranking = 0.33333333333333keywords = cell (Clic here for more details about this article) |
3/5. Squamous cell carcinoma arising in a duplication of the small bowel.A case of squamous cell carcinoma arising in a cystic duplication within the small bowel mesentery of a 65-yr-old man is described. The cyst wall had a double layered smooth muscle coat with intervening ganglionic plexus; part of the cyst was lined by ciliated columnar epithelium. Twelve previously reported cases of carcinoma arising in duplications are reviewed together with present case. In all but one case, the onset of symptoms was probably related to malignant change; the age at presentation ranged from 26 to 65 yrs. Pre-operative diagnosis proved difficult, and led to a delay in the appropriate treatment of some of the five cases involving duplications of the rectum. Duplications of the alimentary tract are encountered only occasionally in adults; malignant change, although rare, should be recognised as a possible complication.- - - - - - - - - - ranking = 1.6666666666667keywords = cell (Clic here for more details about this article) |
4/5. Total excision of mesenteric cysts by laparoscopic surgery: report of two cases.Mesenteric cysts are relatively rare tumors, and most patients present nonspecific abdominal symptoms until developing larger cysts. We report two cases of mesenteric cysts that were totally excised during laparoscopic surgery. The cysts of both patients were located in the mesenterium of the cecum or ascending colon. Under laparoscopy, the cyst was punctured to collect the cystic fluid for cytology and then completely removed without bowel resection. Histological examination revealed cystic lymphangiomas with endothelial cell lining. The postoperative course was uneventful. Laparoscopic treatment of benign abdominal cysts is an alternative safe and less invasive operation.- - - - - - - - - - ranking = 0.33333333333333keywords = cell (Clic here for more details about this article) |
5/5. Mullerian cysts of the mesentery and retroperitoneum: a case report and literature review.Mullerian cyst of the mesentery and retroperitoneum is an extremely rare disease entity. Only two photomicrograph reports have been published. A 47-year-old Korean woman presented with abdominal distention. A mesenteric cystic mass, measuring 25 x 23 x 18 cm, was found between the liver and right adnexa without any connection with adjacent organs. The cyst was multilocular with gray-white, rubbery walls of relatively uniform 0.2 cm thickness. Microscopically, the lining cells were ciliated and cuboidal to low columnar with an incomplete lining of smooth muscle bundles, adipose tissues, lymphovascular spaces, and lymphocytic aggregates. Ultrastructurally, the lining cells had intercellular junctions, and cilia or microvilli on their luminal surface. The lining cells were immunoreactive for cytokeratin, epithelial membrane antigen and vimentin. To the best of our knowledge, this is the first demonstration of ultrastructural and immunohistochemical findings of Mullerian cyst of the mesentery and retroperitoneum in the English literature.- - - - - - - - - - ranking = 1.3333333333333keywords = cell (Clic here for more details about this article) |
