Giant duodenal lipoma: an unusual cause of gastrointestinal bleeding (a case report).

Duodenal lipoma is a rare location of visceral lipomas, most are found incidentally via endoscopy or surgery and usually are asymptomatic. We report the case of a 58-year-old patient with an active bleeding duodenal lipoma. Although endoscopic treatment was scheduled initially, surgical intervention ultimately was indicated due to large size of tumor.

Two-stage free latissimus dorsi flap: a safe strategy for reconstruction of large defects of the abdominal wall.

We report a case of full abdominal wall reconstruction after resection of a dermatofibrosarcoma protuberans. The treatment comprised wide resection with a 5 cm peripheral margin and deep resection to a disease-free anatomical structure. The reconstruction was done in two-stages with a free latissimus dorsi flap.

Primary solitary fibrous tumor of the retroperitoneum.

Solitary fibrous tumor is an uncommon neoplasm affecting adults and typically located in the pleura and can also occur in a large number of other extra thoracic sites. We present the case of a solitary fibrous tumor (SFT) of the retroperitoneum and describe their histopathological and immunohistochemical features. The identification of SFT in the retroperitoneum is of importance because its clinico-pathological behaviour is still unclear. The pathologist plays a fundamental role in establishing both the positive and differential diagnosis.
