Angiosarcoma

A malignant tumor arising from the endothelial cells of the blood vessels. Microscopically, it is characterized by frequently open vascular anastomosing and branching channels. The malignant cells that line the vascular channels are spindle or epithelioid and often display hyperchromatic nuclei. Angiosarcomas most frequently occur in the skin and breast. Patients with long-standing lymphedema are at increased risk of developing angiosarcoma. [from NCI]

Phosphorylation

The creation of a phosphate derivative of an organic molecule. This is usually achieved by transferring a phosphate group from ATP via the action of a kinase. [from NCI]

Canine Hemangiosarcoma

Hemangiosarcoma occurring in a dog. It is an incurable tumor of vascular endothelial cells and occurs more commonly in dogs beyond middle age, and is especially common in certain breeds. Most hemangiosarcomas do not have a known cause. [from NCI]

Inositol preparation

A natural sugar found in cell membrane phospholipids, plasma lipoproteins, and (as the phosphate form) in the nucleus with potential chemopreventive properties. As one of a number of intracellular phosphate compounds, inositol is involved in cell signaling and may stimulate tumor cell differentiation. (NCI04) [from NCI]

Fanconi-Bickel syndrome

Fanconi-Bickel syndrome is a rare but well-defined clinical entity, inherited in an autosomal recessive mode and characterized by hepatorenal glycogen accumulation, proximal renal tubular dysfunction, and impaired utilization of glucose and galactose (Manz et al., 1987). Because no underlying enzymatic defect in carbohydrate metabolism had been identified and because metabolism of both glucose and galactose is impaired, a primary defect of monosaccharide transport across the membranes had been suggested (Berry et al., 1995; Fellers et al., 1967; Manz et al., 1987; Odievre, 1966). Use of the term glycogenosis type XI introduced by Hug (1987) is to be discouraged because glycogen accumulation is not due to the proposed functional defect of phosphoglucomutase, an essential enzyme in the common degradative pathways of both glycogen and galactose, but is secondary to nonfunctional glucose transport. [from GTR]

Hereditary gingival fibromatosis

Gingival fibromatosis is a rare overgrowth condition characterized by a benign, slowly progressive, nonhemorrhagic, fibrous enlargement of maxillary and mandibular keratinized gingiva (summary by Hart et al., 2002). Genetic Heterogeneity of Hereditary Gingival Fibromatosis Other loci for gingival fibromatosis have been mapped to chromosome 5q (GINGF2; 605544), chromosome 2p23.3-p22.3 (GINGF3; 609955), and chromosome 11p15 (GINGF4; 611010). GINGF5 (617626) is caused by mutation in the REST gene (600571) on chromosome 4q12. There is some evidence for a locus on chromosome 2p16-p13 (see MAPPING). [from GTR]

Headache associated with sexual activity

The International Headache Society (1988) classifies headache associated with sexual activity (HSA) as an idiopathic headache under 'miscellaneous headaches unassociated with structural lesions.' Based on initial descriptions, 3 subtypes are differentiated: type 1 is a dull ache in the head and neck that slowly intensifies as sexual excitement increases, and is believed to be caused by muscle contraction similar to tension-type headache; type 2, also called 'vascular-type,' is a sudden severe, explosive headache occurring at orgasm, which may be due to increased intracranial pressure; type 3, the most uncommon type, is a postural headache resembling that caused by decreased CSF pressure, perhaps due to a meningeal tear during coitus (summary by Frese et al., 2003). [from GTR]

X-linked hydrocephalus syndrome

The phenotypic spectrum of L1 syndrome includes: • X-linked hydrocephalus with stenosis of the aqueduct of Sylvius (HSAS); • MASA syndrome (mental retardation, aphasia [delayed speech], spastic paraplegia [shuffling gait], adducted thumbs); • SPG1 (X-linked complicated hereditary spastic paraplegia type 1); and • X-linked complicated corpus callosum agenesis. Males with HSAS are born with severe hydrocephalus, adducted thumbs, and spasticity; intellectual disability is severe. In less severely affected males, hydrocephalus may be subclinically present and documented only because of developmental delay; intellectual disability ranges from mild (IQ: 50-70) to moderate (IQ: 30-50). [from GTR]

Metastasis

The spread or migration of cancer cells from one part of the body (the organ in which it first appeared) to another. The secondary tumor contains cells that are like those in the original (primary) tumor. [from NCI]

Sarcoma

A connective tissue neoplasm formed by proliferation of mesodermal cells. Bone and soft tissue sarcomas are the main types of sarcoma. Sarcoma is usually highly malignant. [from HPO]

Epithelioid Sarcoma

An aggressive malignant neoplasm of uncertain differentiation, characterized by the presence of epithelioid cells forming nodular patterns. The nodules often undergo central necrosis, resulting in a pseudogranulomatous growth pattern. It usually occurs in young adults. The most common sites of involvement are the extremities (distal-type epithelioid sarcoma), and less frequently the pelvis, perineum, and genital organs (proximal-type epithelioid sarcoma). [from NCI]
