An unusual case of a well-differentiated neuroendocrine tumour of the ileum with peritoneal carcinomatosis: a case report.

Neuroendocrine tumours (NETs) are a family of neoplasms that come from neuroendocrine cells and express neural markers, such as synaptophysin or chromogranin A.The current classifications of these tumours are presented by the WHO 2000 classification, based on histological parameters, and the WHO 2010 classification, based on the proliferative index, that divides the NETs into a neuroendocrine tumour of a low grade, neuroendocrine tumour of a intermediate grade and neuroendocrine carcinoma (NEC) of a high grade.We are reporting a very rare case of a G1 low-grade neuroendocrine tumour (NET) of the ileum with a peritoneal carcinomatosis.

Duodenal metastasis from male breast cancer: a case report and review of the literature.

Introduction: Breast cancer is the most frequent type of tumor and the second leading cause of death in women. Metastases are present in nearly 60% of cases at the time of diagnosis with the lymph nodes, skeleton, lungs, brain and liver as the most frequent sites of metastases. Gastrointestinal involvement is rare, present in only 10% of all the cases.

Gastrointestinal stromal tumor with chondroid differentiation.

Gastrointestinal stromal tumors are mesenchymal neoplasms of the gastrointestinal tract that represent less than 1% of all GI tumors. Here the case of such a tumour that, in addition to the classical features, also displayed chondroid differentiation is reported. Chromosomal abnormalities were also investigated.

[Mucinous cystic tumour of the pancreas. A case report].

Although cystic neoplasms and lesions of the pancreas are rare (5% of exocrine tumours), they have attracted a great deal of attention because of their potential curability. In contrast to serous cystic neoplasms, which are generally benign, the mucinous variant is known to have considerable malignant potential. Most authorities agree that no imaging technique (US, CT, MRI) is sufficiently accurate to differentiate between the multiple benign, premalignant and malignant lesions that can be visualised.

[Rupture of voluminous atherosclerotic superficial femoral artery aneurysm].

Atherosclerotic aneurysms of the superficial femoral artery are very uncommon. We report a case of a ruptured superficial femoral artery aneurysm which was successfully treated surgically, and compare our data with those emerging from a review of the literature. We observed a 74-year-old man who presented with a suspected rupture of a superficial femoral artery aneurysm.
