A retroperitoneal cyst with unusual urinary histogenesis: clinical and immunomorphological characteristics.

Primary retroperitoneal cysts are rare benign lesions which often present as an incidental radiological finding and also cause abdominal symptoms. A 47-year-old woman was admitted to the surgery unit because of right-sided abdominal pain. Computed tomographic scan investigation confirmed a circumscribed, oval, dishomogeneous mass in the right anterior pararenal space.

[Acute abdomen for perforated gastrointestinal stromal tumor (GIST). A case report].

The authors report on a case of voluminous perforated gastrointestinal stromal tumor (GIST) of small intestine and make a review to the light of most recent clinicopathologic advancements. The first clinical manifestation as acute abdomen due to their perforation extremely rare. Gastrointestinal stromal tumor (GIST) represent a rare group of multiform tumors with various biological behaviour.

[Gastrointestinal stromal tumour: our experience].

Gastrointestinal stromal tumours (GISTs) are the most common mesenchymal neoplasms of the gastrointestinal tract. These tumours originate in Cajal interstitial cells and the majority are located in the stomach and small intestine. They frequently develop in males aged 50-60 years.

Role of osteopontin in breast cancer patients.

Aim And Background: In breast cancer, as in almost all neoplastic diseases, the prognosis is strictly related to the invasive capacity, local and distant, that characterizes the growth of all tumors. Since the mechanisms that regulate replication of the neoplastic cells, with consequent capacity to metastasize, are not completely known, identification of new markers represents the gold standard of research in the stratification of patients with such a pathology. Osteopontin, a specific phosphoglycoprotein isolated from extracellular bone matrix and actively involved in mechanisms of bone reabsorption, appears to play a key role in osteoclastogenesis at the level of the skeleton in some pathologic situations.

Volvulus due to a giant sigmoid diverticulum: a rare cause of intestinal occlusion.

The case of a giant sigmoid diverticulum complicated by a volvulus of the bowel is reported. After an exhaustive literature review, the Authors analyse the aetiopathogenetic, physiopathological and clinical aspects of this rare condition, considering its diagnostic and therapeutic implications. The Authors describe surgical problems and therapeutic management, pointing out that without an accurate study by radiological imaging, it is very difficult to diagnose the condition, particularly when no specific symptoms have been observed.

Rare localizations of echinococcosis: personal experience.

Background: The rare localizations of hydatidosis represent an interesting topic, especially with reference to epidemiological and diagnostic problems. Hydatid disease, common in Mediterranean countries, still remains endemic in some regions of Italy.

Methods: In the period April 1983-October 2003 73 patients with hydatid disease were observed.

Ischemic colitis following colonoscopy in a systemic lupus erythematosus patient: report of a case.

Background: Ischemic colitis is an uncommon complication in patients with systemic lupus erythematosus but may be precipitated by colonoscopy.

Case Report: A 43-year-old female with systemic lupus erythematosus under treatment with immunosuppressive drugs and prednisone was submitted to colonoscopy because of a change in bowel habit. Apart from the presence of a small metaplastic polyp, colonoscopy showed only a few erythematosus areas in the sigma and left colon.

Protective effects of SP600125 a new inhibitor of c-jun N-terminal kinase (JNK) and extracellular-regulated kinase (ERK1/2) in an experimental model of cerulein-induced pancreatitis.

Extracellular regulated kinases (ERK1/2) and c-Jun N-terminal Kinases (JNK), are generally considered to play a key role in signal transduction pathways activated by a wide range of stimuli. We studied the effects of SP600125, a novel inhibitor of both JNK and ERK1/2, in male C57/BL6 mice given with an hyper-stimulating dose of cerulein (50 microg/kg for each of four injections at hourly intervals) to elicit secretagogue-induced pancreatitis. A control group received four intra-peritoneal injections of 0.

Epithelioid hemangioendothelioma of the stomach: clinical-pathological features, nosologic setting, and surgical therapy. Report of a case.

Vascular tumors of the stomach represent 0.9%-3.3% of all gastric neoplasms.
