The National Library of Medicine (NLM), on the campus of the National Institutes of Health in Bethesda, Maryland, is the world's largest medical library. The Library collects materials and provides information and research services in all areas of biomedicine and health care.
1) A benign neoplasm derived from connective tissue, consisting chiefly of polyhedral and stellate cells that are loosely embedded in a soft mucoid matrix, thereby resembling primitive mesenchymal tissue. It occurs frequently intramuscularly where it may be mistaken for a sarcoma. It appears also in the jaws and the skin. (From Stedman, 25th ed)
2) A benign soft tissue neoplasm characterized by the presence of spindle and stellate cells, lobulated growth pattern, and myxoid stroma formation.
3) A benign soft tissue neoplasm characterized by the presence of neoplastic spindle and stellate cells in a myxoid stroma.

1) A benign tumor of the nervous system that may occur sporadically or in association with Hippel-Lindau disease. It accounts for approximately 2% of intracranial tumors, arising most frequently in the cerebellar hemispheres and vermis. Histologically, the tumors are composed of multiple capillary and sinusoidal channels lined with endothelial cells and clusters of lipid-laden pseudoxanthoma cells. Usually solitary, these tumors can be multiple and may also occur in the brain stem, spinal cord, retina, and supratentorial compartment. Cerebellar hemangioblastomas usually present in the third decade with intracranial hypertension, and ataxia. (From DeVita et al., Cancer: Principles and Practice of Oncology, 5th ed, pp2071-2)
2) A hemangioma especially of the cerebellum that tends to be associated with von Hippel-Lindau disease.

1) A bile pigment that is a degradation product of heme.
2) Substance formed when red blood cells are broken down. Bilirubin is part of the bile, which is made in the liver and is stored in the gallbladder. The abnormal buildup of bilirubin causes jaundice.

1) A biological process consisting of chromosomal rearrangements and duplications. These phenotypes are often seen in the karyotype of cancer cells, where there is an imbalance between the mechanisms of cell-cycle control and mutation rates within aberrant genes. Ataxia telangiectasia is a disease that is resultant from mutations in the ATM gene, which is a cell cycle checkpoint gene. Nijmegen breakage syndrome is also a disease characterized by chromosomal and genomic instability.
2) An increased tendency of the GENOME to acquire MUTATIONS when various processes involved in maintaining and replicating the genome are dysfunctional.

1) A birth defect is an abnormality present at birth. Also called a congenital defect, it can be caused by a genetic mutation, an unfavorable environment during pregnancy, or a combination of both. The effect of a birth defect can be mild, severe, or incompatible with life.
2) A physical or biochemical defect (as cleft palate, phenylketonuria, or Down syndrome) that is present at birth and may be inherited or environmentally induced.
Industry:Health care
1) A bluish or purplish discoloration of the skin and mucous membranes due to an increase in the amount of deoxygenated hemoglobin in the blood or a structural defect in the hemoglobin molecule.
2) Blue-colored skin caused by too little oxygen in the blood.
