Management of malignant struma ovarii: is aggressive therapy justified? Case report and literature review.

Background: Struma ovarii (SO) is a rare ovarian teratoma containing predominantly thyroid tissue. In rare situations SO may develop malignancy. Most cases of malignant struma ovarii (MSO) are diagnosed after surgical removal, based on histopathological examination.

Gastrointestinal Stromal Tumors - Diagnosis and Surgical Treatment.

Gastrointestinal stromal tumors (GIST) are the most common mesenchymal tumors of the gastrointestinal tract, previously classified as leiomyomas, leiomyosarcomas, leiomyoblastomas or schwannomas. They are now recognized as a distinct entity with origin in the mesodermal interstitial cell of Cajal, cells that express the c-KIT protein (tirozine kinase receptor). The definitive diagnosis is established by immunohistochemistry, more than 95% of GISTs being positive for CD117.

The surgical treatment for Crohn's disease.

Introduction: Crohn's disease is a chronic idiopathic medical and surgical disease, in which the transmural intestinal inflammatory process frequently leads to complications such as strictures or fistulae. The disease is considered to be the result of an imbalance between the proinflammatory mediators and the anti-inflammatory ones; it can be localized on any segment of the gastrointestinal tract, but it especially affects the terminal ileum. The purpose of the study is to assess Crohn's disease from the point of view of the complications requiring surgical treatment, the manner in which they are solved, as well as the postoperative evolution.

[Unique duodenal hamartomatous polyp--case report].

Duodenal tumors are very rare tumors, with the lower incidence among the tumors of the small bowel, whose frequence is less than 5 % of all digestive tumors. In most of the cases these tumors remain asymptomatic, sometimes the entire life. When they become symptomatic, their first manifestation is the loss of digested blood (melena), secondary anemia and obstructive symptomatology.

[Gastrointestinal stromal tumor with primary hepatic unique location--clinical case].

The gastrointestinal stromal tumors are mesenchymal tumors whose primary extradigestive location is very rare (less than 10% primary liver localization). We present a clinical case of primary hepatic location of GIST in a 28 year-old patient. The discovery of this tumor is a chance, the patient presenting for non-specific dyspeptic syndrome and epigastralgia.
