Extragastrointestinal stromal tumor (EGIST) has been reported to occur only rarely, and the cases of this disease appearing as cystic masses are also known to be very infrequent. Along with a review of the related articles, we report here on a case of EGIST arising from the omentum that was seen as a multiloculated large cystic mass with multiple thick septa and a solid component.
Omentum*

Omentum has the characteristic that it readily develops vascular anastomosis with adjacent tissues. It is suitable for eliminating a dead space regardless of the size, shape or site in the treatment of chronic osteomyelitis by use of technique of microvascular anastomoses. We report a case of chronic osteomyelitis treated by transplantation of autogenous omentum with microvascular anastomsis.

The omentum is unique in that it is the body tissue developed for the resolution of local inflammatory processes because of combination of its blood supply and abundant lymphatic drainage. Thus, the use of omentum is well established for the more complex reconstruction of the urinary tract. We managed 3 cases of multiple severe renal injury using omentum and results were favorable.

Herein, we report on a case of primary torsion of the greater omentum with segmental infarction, which should provide useful information for the preoperative diagnosis of future such cases. Primary torsion of the greater omentum with omental infarction is a rare condition. There are only a few radiological reports of secondary torsion of the greater omentum caused by the hernial sac. During surgical exploration, infarction of the greater omentum was identified, due to the observation of omental torsion without any underlying cause. We describe a patient with characteristic computed tomography (CT) findings of primary omental torsion with segmental infarction, which correlated with the operative and pathologic results.

Extensive and complicated defects on the body call for an omnipotent tool for a perfect reconstruction. Flaps derived from the omentum has many advantages over the conventional flaps. From 1999 to 2004, Omental flaps were applied for various soft tissue reconstructions. Among total 20 total 7 cases were for immediate reconstruction, 2 cases for chronic infection, 3 cases for simultaneous reconstruction of two defects, 4 cases for functional joint reconstruction and 4 cases were for flow- through revascularization. Among these cases, 3 cases were operated with minimal incision harvest technique. There were no complete flap failures, partial necrosis of the distal parts were noted on three cases. The omental flap is indicated on a large contaminated defect reconstruction due to its large size, well-vascularized, and malleable properties. The omental flap provides several additional advantages over other flaps, which are; the availability of the one staged simultaneous reconstruction of two defects with one flap, providing gliding function for the joint motion, and a flow-through characteristics with long vascular pedicle. But there are some serious shortcomings, including a long abdominal scar and intraabdominal problems. However, these are rare and can be minimized with our minimal incision technique. Due to its unique characteristics. the omentum is one of the ideal tissues for the reconstruction of the complicated soft tissue defects due to its unique characteristics.

Xanthogranulomatous cystitis is a rare benign chronic inflammatory disease of unknown etiology. Herein, an extensive case presenting as a mass around the dome of bladder, with infiltration of perivesical fat and a part of omentum, is reported.

Cystic lymphangioma is uncommon angiomatous tumor that mainly occurs in the neck. Less than 1% of these tumors affect the mesentery, retroperitoneum and greater omentum. In particular, the cystic lymphangioma involving the mesentery and the retroperitoneum is a rare lesion. We report here on an uncommon case of cystic lymphangioma that presented as a multilocular mass involving the mesentery and the retroperitoneum, and we also present a brief review of the relevant literature.

Primary peritoneal cancer is a rare tumor, which may be mesothelial or mullerian in nature. It can develop from unifocal or multifocal origin and the clinical and histologic disease entities are similar to those of primary papillary serous carcinoma of the ovary, but the main features of primary peritoneal cancer are widely disseminated malignancy along the peritoneal surfaces, the omentum, and abdominal viecera, with minimal or no ovarian involvement. Recently investigators have analyzed the morphology of these tumors and have used histochemical, eletron microscopic and immunohistologic techniques in an attempt to identify, characterize, and categorize. We have experienced a case of a primary peritoneal cancer which developed in the patient who had probably a previous total hysterectomy and both salpingooophorectomy.

Secondary involvement of the eye and orbit occurs in about two to four percent of the patients with generalized lymphomatosis and/or other forms of lymphomatous tumors. Of the extranodal primary lesions which are more rare manifestation of the malignant lymphoma, only one percent occur in the eye and orbit. The malignant lymphoma of the orbit is consequently a relatively uncommon condition. The authors experienced a case of the malignantly mphoma of the orbital margin and treated by local radiation therapy with Co60, and the lesions regressed rapidly and completely disappeared. There has been no sign of recurrence at the orbital region, but we found that the malignant lymphomatous lesions involved in the pancreas and omentum by the surgical laparotomy. The patient died of poor course of the disease about 20 days after discharge.
