Introduction Surgical therapy remains the gold standard for treatment of liver neoplasms. In the last 20 years we assisted to an increase of survival in patients with a diagnosis of hepatocellular carcinoma (HCC), according to screening programs, and a multimodal therapeutical approach. In the last years it was an increase of elderly patients with HCC cause of the increase of infection of HCV a...

Chordomas are the most common sacrococcygeal tumors in adults. They have a high recurrence rate, are locally aggressive, and are resistant to radiation therapy. Radio frequency is a relatively new therapeutic technique, used primarily in the treatment of liver tumors; however, its application has widened to include other neoplasms. We report its use in the palliative treatment of chordomas in t...

Carcinoid tumours occur predominantly in the gastrointestinal tract and bronchial system of the lungs, but they can originate in less common anatomical sites such as the testes, which accounts for <1% of all testicular neoplasms. Carcinoid tumour is a rare and indolent neoplasm with the potential for distant metastasis. We report on a man with metastatic right testicular carcinoid tumour who ha...

Diagnosis and treatment of hepatic tumors are a challenge for the surgeon in some situations. There are many histologic types of these neoplasms, and their diagnoses are increasing. Leyomioma of the liver is a rare pathology that is presented in this article in a 44 years old woman without immunosuppression. A review about its clinical aspects, image diagnosis and surgical therapy is discussed,...

Pregnant rats were fed a diet to which groundnut meal containing aflatoxin was added. The rats were fed the diet either prior to or after parturition or for both periods. The progeny developed inflammatory, hyperplastic,and neoplastic changes in the livers that were not seen in progeny of control animals ted a diet that did not contain aflatoxin. Malignant liver neoplasms were seen in the proge...

Post-transplant lymphomas or other lymphoproliferative lesions, which were usually associated with Epstein-Barr virus infections, developed in 8, 4, 3, and 2 recipients, respectively, of cadaveric kidney, liver, heart, and heart-lung homografts. Reduction or discontinuance of immunosuppression caused regression of the lesions, often without subsequent rejection of the grafts. Chemotherapy and i...

The prevalence of primary cancer of the liver in Africa and in certain parts of Asia is a problem that should attract increasing attention. In a series of papers Berman (1, 2, 3) describes its frequency and pathology amongst the Bantu in South Africa, and in discussing the possible etiological factors (4) draws attention to its coincidence with cirrhosis. He enumerates a number of other conditi...

Primary benign and malignant neoplasm of the small bowel are rare. Malignant tumours often present late symptoms resulting in a poor prognosis. Early detection of small bowel neoplasms is desirable but challenging for both clinicians and radiologists. Conventional double contrast enteroclysis was the method of choice in small bowel imaging but is increasingly being replaced by cross-sectional i...

Background: Isolated pancreatic metastases of other neoplasms are an uncommon pathology, particularly with a colo-rectal cancer origin. Surgery represents the single hope for a long-term survival in these patients, but most of the previously reported patients in the literature underwent standard pancreatic resections. A central pancreatectomy is a non-standardized pancreatic resection, which wa...

Immature T cell neoplasms in three young Holstein cattle with neoplastic involvement of the thymus are described. Case 1, with a precursor T lymphoblastic leukemia (calf form of leukosis), was an 86-day-old female calf. The leukemia was characterized by replacement of the bone marrow and spleen by leukemia cells, but preservation of epithelial frameworks throughout the thymus. The other two neo...
