A 48-year-old woman underwent total abdominal hysterectomy with conservation of the ovaries and tubes. Histology showed a well-circumscribed smooth muscle tumor with foci of degeneration (including infarct-type necrosis) but no coagulative tumor cell necrosis and only mild focal cytological atypia. She presented, 24 years later with shortness of breath and abdominal distension and underwent bil...

omental cysts occur rarely. patients with omental cysts usually present with abdominal distention and a painless abdominal mass. in children it may present as an acute abdomen due to intestinal obstruction. the most common physical finding of an omental cyst is a freely movable abdominal mass, which should be considered in differential diagnosis of these cases. the diagnostic procedures include...

the omentum and the stranding continued inferiorly into left inguinal hernia sac (Fig. 2). The diagnosis of omental torsion with hernia was confirmed on laparotomy. Omental torsion usually occurs on the right side because of greater mobility of the right omentum. A left-sided omental torsion is rare and is difficult to diagnose clinically. Torsion may be primary, or secondary to underlying caus...

The messenger RNA (mRNA) distribution of 60 proteins was examined in the 3 fractions obtained by collagenase digestion (fat cells and the nonfat cells comprising the tissue remaining after collagenase digestion [matrix] and the stromovascular cells) of omental adipose tissue obtained from morbidly obese women undergoing bariatric surgery. Fat cells were enriched by at least 3-fold as compared w...

BACKGROUND Haem oxygenase (HO)-1, an enzyme that degrades haem, plays a key role in the regulation of the inflammatory response and insulin resistance. The aim of this study was to evaluate the role of HO-1 in the regulation of insulin resistance and glucose tolerance in women with polycystic ovary syndrome (PCOS). METHODS Omental adipose tissue and human peripheral blood mononuclear cells (P...

Patients with glucocorticoid excess develop central obesity, yet in simple obesity, circulating glucocorticoid levels are normal. We have suggested that the increased activity and expression of the enzyme 11beta-hydroxysteroid dehydrogenase type 1 (11betaHSD1) generating active cortisol from cortisone within adipose tissue may be crucial in the pathogenesis of obesity. In this study primary cul...

BACKGROUND Omental infarction is a rare entity that usually causes symptoms similar to those of appendicitis. Ultrasound or computerized tomography scan can diagnose omental infarction preoperatively. METHODS We treated two patients with omental infarction by performing a laparoscopic omentectomy in each one. RESULTS The pathology verified the operative diagnosis, and both patients were dis...

  Hydatid disease is a parasitic infection caused by Echinococcus granulosus (larval form) in humans with lesions most frequently encountered in the liver and lungs. It can rarely involve extra-hepatic organs. It is endemic in some regions of Iran. The omental hydatid cyst is a very rare manifestation of the disease. This report presents the interesting case of a very large omental hydatid cyst.

In the present study we report three cases of solitary omental metastasis from non-small cell lung cancer, which had been surgically resected at our institute. The primary site was resected in one patient (case 1) and the other two patients were treated with chemotherapy and demonstrated complete response (cases 2 and 3). The omental metastasis appeared 4 months after pneumonectomy in case 1. T...
