Angiosarcoma is a rare malignant tumor with an aggressive clinical course and a poor prognosis. Intraperitoneal angiosarcoma, especially originating from the omentum, is extremely rare. We report a case of radiation-induced angiosarcoma of the omentum that arose in a 38-year-old female seven years after concurrent chemoradiotherapy for cervical cancer. The primary tumor was unknown until diagno...

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...

hydatid disease (hd) is caused by echinococcus granulosus and is endemic in many parts of the world. this parasitic tapeworm can produce cysts in almost every organ of the body, with the liver and lung being the most frequently targeted organs. peritoneum, omentum, and mesentery are among these unusual locations, which can cause diagnostic challenge and treatment delay. this review provides inf...

Inguinal hernia with acute appendicitis known as Amyand's hernia is uncommon. It may clinically manifest as acute scrotum, inguinal lymphadenitis, or strangulated hernia. The presentation of Amyand's hernia with acute scrotum has been rarely described. Also, the manifestation of infarcted omentum in the inguinal hernia has been described in one case previously. However, the coexistence of perfo...

Leiomyosarcoma is a rare tumor that originates in the smooth muscle, usually in the gastrointestinal tract, the retroperitoneum and the genitourinary tract. The omentum has been rarely reported as a primary site of occurrence with leiomyosarcoma. A 72 year-old woman, with palpable mass on the left upper quadrant of abdomen and weight loss, was admitted to St. Paul's Hospital. Abdominal CT scan ...

UNLABELLED We report a case of a 43 years old male that presented to emergency room for epigastric and mesogastric pain associated with a palpable abdominal mass. Explorative laparotomy showed a well capsulated tumour of the lesser omentum, sized 20 x 16 x 10 cm. Histologically the mass was charaterized by thick fibrous capsula, with areas of moderate cellularity alternated to areas of sclerosi...

Transabdominal ultrasound not always allows to determine the nature of ascites based solely on its characteristics. AIM The aim of the study was to present difficulties in determining the nature of ascites using transabdominal ultrasonography solely based on extra-organ lesions as well as, after the inclusion of the overall abdominal assessment and the clinical picture. MATERIALS AND METHOD...

Advanced ovarian cancer usually spreads to the visceral adipose tissue of the omentum. However, the omental stromal cell-derived molecular determinants that modulate ovarian cancer growth have not been characterized. Here, using next-generation sequencing technology, we identify significantly higher levels of microRNA-21 (miR21) isomiRNAs in exosomes and tissue lysates isolated from cancer-asso...

Various techniques of cardiac tissue engineering have been pursued in the past decades including scaffolding strategies using either native or bioartificial scaffold materials, entrapment of cardiac myocytes in hydrogels such as fibrin or collagen and stacking of myocyte monolayers. These concepts aim at restoration of compromised cardiac function (e.g. after myocardial infarction) or as experi...

Differentiation of autologous stem cells into functional transplantable tissue for organ regeneration is a promising regenerative therapeutic approach for cancer, diabetes, and many human diseases. Yet to be established, however, is differentiation into tissue capable of producing erythropoietin (EPO), which has a critical function in anemia. We report a novel EPO-producing organ-like structure...
