Malignant disease

The differential diagnosis between primary mesenteric lymphoma and others peritoneum diseases such as peritoneal carcinomatosis, malignant primary peritoneal mesotheliomas, tuberculous peritonitis, sarcomatosis, diffuse peritoneal leiomyomatosis or benign splenosis, constitutes a major problem in imaging techniques.

Ovarian cancer constitutes one of the most lethal gynecologic malignancies for females. Currently, early detection strategies and therapeutic options for ovarian cancer are far from satisfactory, leading to high diagnosis rates at late stages and disease relapses. New avenues of therapy are needed that target key processes in ovarian cancer progression.

Osteosarcoma (OS) is a differentiation disease caused by the genetic and epigenetic differentiation of mesenchymal stem cells into osteoblasts. OS is a common, highly malignant tumor in children and adolescents. Fifteen to 20 % of the patients find distant metastases at their first visit.

Pancreatic ductal adenocarcinoma (PDAC), one of the most lethal malignancies, is increasing in incidence. However, the stromal reaction pathophysiology and its role in PDAC development remain unknown. We, therefore, investigated the potential role of histological chronic pancreatitis findings and chronic inflammation on surgical PDAC specimens and disease-specific survival (DSS).

The Ryanodine Receptor-1 gene (RYR-1) is located in the 6p11 → q21 region on the No. 6 chromosome of pigs. RYR-1 is being investigated in several studies as a potentially important gene that is an indicator of pork quality. In this article, PCR-RFLP was used to analyze RYR-1 polymorphism in 19 Mong Cai pigs, 2 Yorkshire pigs and their 64 F1 generation pigs.

The expression of proteoglycans (PGs), essential macromolecules of the tumor microenvironment, is markedly altered during malignant transforma-tion and tumor progression. Synthesis of stromal PGs is affected by factors secreted by cancer cells and the unique tumor-modified extracellular matrix may either facilitate or counteract the growth of solid tumors.

Abstract Dermatofibrosarcoma protuberans is an uncommon locally aggressive malignant neoplasm that most frequently appears in the trunk, followed by the extremities, head, and neck. But occurrence in the breast is extremely rare. We present a case of a 28-year-old woman, who had a history of trauma 5 years previously and excision 1 year before presentation at our clinic. We performed wide excision, together with microscopic and immunohistochemical analysis. No postoperative oncologic treatment was used and she remains disease-free 1 year after the surgery without any tumor recurrence.

Among the subspecialties of internal medicine, medical oncology may have had the greatest impact in changing the practice of medicine in the past four decades, as curative treatments have been identified for a number of previously fatal malignancies such as testicular cancer, lymphomas, and leukemia. New drugs have entered clinical use for disease presentations previously either untreatable or amenable to only local means of therapy, such as surgery and irradiation.

Primary (Spontaneous) Bacterial Peritonitis Peritonitis is either primary (without an apparent source of contamination) or secondary. The types of organisms found and the clinical presentations of these two processes are different. In adults, primary bacterial peritonitis (PBP) occurs most commonly in conjunction with cirrhosis of the liver (frequently the result of alcoholism).

Harrison's Internal Medicine Chapter 104. Acute and Chronic Myeloid Leukemia Acute and Chronic Myeloid Leukemia: Introduction The myeloid leukemias are a heterogeneous group of diseases characterized by infiltration of the blood, bone marrow, and other tissues by neoplastic cells of the hematopoietic system. In 2006 the estimated number of new myeloid leukemia cases in the United States was 16,430. These leukemias comprise a spectrum of malignancies that, untreated, range from rapidly fatal to slowly growing.

Heavy Chain Diseases The heavy chain diseases are rare lymphoplasmacytic malignancies. Their clinical manifestations vary with the heavy chain isotype. Patients secrete a defective heavy chain that usually has an intact Fc fragment and a deletion in the Fd region. Gamma, alpha, and mu heavy chain diseases have been described, but no reports of delta or epsilon heavy chain diseases have appeared. Molecular biologic analysis of these tumors has revealed structural genetic defects that may account for the aberrant chain secreted.

Incidence and Prevalence About 19,900 cases of myeloma were diagnosed in 2007, and 10,790 people died from the disease in the United States. Myeloma increases in incidence with age. The median age at diagnosis is 68 years; it is uncommon under age 40. The yearly incidence is around 4 per 100,000 and remarkably similar throughout the world. Males are more commonly affected than females, and blacks have nearly twice the incidence of whites. Myeloma accounts for ~1% of all malignancies in whites and 2% in blacks; 13% of all hematologic cancers in whites and 33% in blacks. The incidence of...

The diagnosis of Hodgkin's disease is established by review of an adequate biopsy specimen by an expert hematopathologist. In the United States, most patients have nodular sclerosing Hodgkin's disease, with a minority of patients having mixed-cellularity Hodgkin's disease. Lymphocyte-predominant and lymphocyte-depleted Hodgkin's disease are rare. Mixed-cellularity Hodgkin's disease or lymphocyte-depletion Hodgkin's disease are seen more frequently in patients infected by HIV (Fig. 105-11).

A number of other late side effects from the treatment of Hodgkin's disease are well known. Patients who receive thoracic radiotherapy are at very high risk for the eventual development of hypothyroidism and should be observed for this complication; intermittent measurement of thyrotropin should be made to identify the condition before it becomes symptomatic. Lhermitte's syndrome occurs in ~15% of patients who receive thoracic radiotherapy. This syndrome is manifested by an "electric shock" sensation into the lower extremities on flexion of the neck.
