Collision Tumor Composed of an Inflammatory Myofibroblastic Tumor and Adenocarcinoma of the Colon: a Rare Entity.

This report presents the case of an 83-year old man with a collision tumor consisting of an inflammatory myofibroblastic tumor (IMT) and adenocarcinoma of the left colon. As the clinical and radiologic features of IMT are non-specific, only the accurate histopathological examination from the left hemicolectomy specimen was diagnostic. Although the prognosis of a colorectal IMT seemed more favorable than in other sites, four months after surgery the patient developed a tumor relapse.

Advantages of percutaneous abdominal biopsy under PET-CT/ultrasound fusion imaging guidance: a pictorial essay.

Positron emission tomography (PET) is a functional imaging technique that can investigate the metabolic characteristics of tissues. Currently, PET images are acquired and co-registered with a computed tomography (CT) scan (PET-CT), which is employed for correction of attenuation and anatomical localization. In spite of the high negative predictive value of PET, false-positive results may occur; indeed, Fluorine 18 ((18)F)-fluorodeoxyglucose ((18)F-FDG) uptake is not specific to cancer.

CDKN2A is the main susceptibility gene in Italian pancreatic cancer families.

Background Most familial pancreatic cancer (FPC) remains unexplained. The identification of individuals with a high genetic risk of developing pancreatic adenocarcinoma (PC) is important to elucidate its biological basis and is critical to better define emerging strategies for the detection of early pancreatic neoplasms. Patients and methods A series of 225 consecutively enrolled patients with PC were tested for CDKN2A mutations.

Gastrointestinal bleeding due to suspected anisakiasis: challenging differential diagnosis for a rare disease.

As compared with Eastern countries, the incidence of gastrointestinal diseases caused by the ingestion of nematode eggs is very low in Europe, in spite of the fact that the consumption of raw fish has increased in these countries as well in recent years. The authors present here, a rare case of gastrointestinal bleeding due to Anisakis simplex. This is a very uncommon clinical presentation which rise several problems in diagnosis and management.

Diffusion of laparoscopic appendectomies in Italy: a national audit.

A national audit focused on laparoscopic appendectomy was promoted by the Italian Association of Hospital Surgeons (ACOI). Four-hundred and sixty surgical practices received an e-mail questionnaire. Data concerning epidemiology, timetable, surgeon's age, selection of patients, laparotomic conversion, behaviour in the case of a normal appendix, and technical aspects were investigated.

Assessment of hepatic reserve for the indication of hepatic resection: how I do it.

Despite the careful selection of cirrhotic patients with hepatic neoplasms, liver resection for these patients remains associated with greater risk than in patients without underlying liver disease. The most rational indications for resective surgery in patients with hepatic neoplasms and cirrhosis are nonprogressive cirrhosis and good functional reserve. Therefore, evaluation of hepatic reserve is mandatory for hepatectomy candidates.
