BACKGROUND Milky spots in the greater omentum of some animals are well organized perivascular infiltrates of leucocytes, and are considered to have characteristics of secondary lymphoid tissue. To determine whether milky spots in the human greater omentum can also be regarded as secondary lymphoid tissue, we studied milky spots in an unstimulated state. (More)
Multifocal fibrosclerosis, as the name implies, concerns disseminated fibrous processes that manifest as Riedel's thyroiditis, idiopathic retroperitoneal fibrosis, mediastinal fibrosis, sclerosing cholangitis, and pseudotumor of the orbit. Certain cases of fibrosis of the parotid gland, the lacrimal glands, and the lung may belong in the same category. The(More)
Recent data from literature show an increase in incidence and mortality due to soft tissue sarcoma (STS). In the Netherlands age-standardised mortality rates of soft tissue sarcoma (STS) over the period 1950-1988 show a more than fivefold increase. Males predominate over females by a factor of 1.17. Age-adjusted hospital admission rates in 1980-1988 show an(More)
Milky spots in the greater omentum are well organized perivascular infiltrates of leukocytes which are probably involved in the clearance of tumor cells from the peritoneal cavity. In milky spots, macrophages are the predominant cell type forming a distinct population of cells. To investigate whether these macrophages have a function in the control of(More)
Intraoperative ultrasonography (IOUS) of the liver is a very useful tool during surgery for gastrointestinal tumors or hepatic tumors. In a prospective study of 82 elective operations for 57 gastrointestinal tumors and 25 hepatic tumors or metastases, we compared IOUS with preoperative ultrasonography, CT-scanning and MRI. IOUS supplied additional(More)
No aetiological factors are at present known in the pathogenesis of liposarcomas. Benign lipomatous disorders, such as lipomas and lipomatosis, generally do not predispose to the development of liposarcomas. A case is presented of a patient with multicentric retroperitoneal liposarcomas, associated with retroperitoneal lipomatosis and preceded by a long(More)
The gastrointestinal tract, besides being the organ responsible for nutrient absorption, is also a metabolic and immunological system, functioning as an effective barrier against endotoxin and bacteria in the intestinal lumen. The passage of viable bacteria from the gastrointestinal tract through the epithelial mucosa is called bacterial translocation.(More)
The muscular dystrophies (MDs) are genetic disorders of muscle degeneration due to mutations in genes that encode a wide variety of proteins. Dysferlinopathy are characterized by the absence of dysferlin in skeletal muscle and an autosomal recessive mode of inheritance. Both histological and ultrastructural pathology have been well established in(More)
Proliferation variables such as mitotic activity and the percentage of S-phase cells have been shown to be of prognostic value in many tumors, especially in breast cancer. However, some studies reported a decrease in mitotic activity caused by delay in fixation of the tissue. In contrast, other studies showed that the identifiability of mitotic figures(More)
