Label	Id	Description
Carcinoma in Situ	D002278	[A lesion with cytological characteristics associated with invasive carcinoma but the tumor cells are confined to the epithelium of origin, without invasion of the basement membrane.]
Carcinoma 256, Walker	D002279	[A transplantable carcinoma of the rat that originally appeared spontaneously in the mammary gland of a pregnant albino rat, and which now resembles a carcinoma in young transplants and a sarcoma in older transplants. (Stedman, 25th ed)]
Carcinosarcoma	D002296	[A malignant neoplasm that contains elements of carcinoma and sarcoma so extensively intermixed as to indicate neoplasia of epithelial and mesenchymal tissue. (Stedman, 25th ed)]
Epilepsy, Partial, Sensory	D020937	[A disorder characterized by recurrent focal onset seizures which have sensory (i.e., olfactory, visual, tactile, gustatory, or auditory) manifestations. Partial seizures that feature alterations of consciousness are referred to as complex partial seizures (EPILEPSY, COMPLEX PARTIAL).]
Epilepsies, Partial	D004828	[Conditions characterized by recurrent paroxysmal neuronal discharges which arise from a focal region of the brain. Partial seizures are divided into simple and complex, depending on whether consciousness is unaltered (simple partial seizure) or disturbed (complex partial seizure). Both types may feature a wide variety of motor, sensory, and autonomic symptoms. Partial seizures may be classified by associated clinical features or anatomic location of the seizure focus. A secondary generalized seizure refers to a partial seizure that spreads to involve the brain diffusely. (From Adams et al., Principles of Neurology, 6th ed, pp317)]
Mannosidase Deficiency Diseases	D044904	[Diseases caused by the loss of one or more enzymes involved in the hydrolysis of mannoside linkages (MANNOSIDASES). The defects in enzyme activity are primarily associated with genetic mutation of the genes that codes for a particular mannosidase isoenzyme.]
Leukomalacia, Periventricular	D007969	[Degeneration of white matter adjacent to the CEREBRAL VENTRICLES following cerebral hypoxia or BRAIN ISCHEMIA in neonates. The condition primarily affects white matter in the perfusion zone between superficial and deep branches of the MIDDLE CEREBRAL ARTERY. Clinical manifestations include VISION DISORDERS; CEREBRAL PALSY; PARAPLEGIA; SEIZURES; and cognitive disorders. (From Adams et al., Principles of Neurology, 6th ed, p1021; Joynt, Clinical Neurology, 1997, Ch4, pp30-1)]
Infant, Premature, Diseases	D007235	[Diseases that occur in PREMATURE INFANTS.]
Encephalomalacia	D004678	[Softening or loss of brain tissue following CEREBRAL INFARCTION; cerebral ischemia (see BRAIN ISCHEMIA), infection, CRANIOCEREBRAL TRAUMA, or other injury. The term is often used during gross pathologic inspection to describe blurred cortical margins and decreased consistency of brain tissue following infarction. Multicystic encephalomalacia refers to the formation of multiple cystic cavities of various sizes in the cerebral cortex of neonates and infants following injury, most notably perinatal hypoxia-ischemic events. (From Davis et al., Textbook of Neuropathology, 2nd ed, p665; J Neuropathol Exp Neurol, 1995 Mar;54(2):268-75)]
Epilepsy, Partial, Motor	D020938	[A disorder characterized by recurrent localized paroxysmal discharges of cerebral neurons that give rise to seizures that have motor manifestations. The majority of partial motor seizures originate in the FRONTAL LOBE (see also EPILEPSY, FRONTAL LOBE). Motor seizures may manifest as tonic or clonic movements involving the face, one limb or one side of the body. A variety of more complex patterns of movement, including abnormal posturing of extremities, may also occur.]
beta-Mannosidosis	D044905	[An inborn error of metabolism marked by a defect in the lysosomal isoform of BETA-MANNOSIDASE that results in lysosomal accumulation of mannose-rich intermediate metabolites containing 1,4-beta linkages. The human disease occurs through autosomal recessive inheritance and manifests in the form of a variety of symptoms that depend upon the type of gene mutation.]
Trichuriasis	D014257	[Infection with nematodes of the genus TRICHURIS, formerly called Trichocephalus.]
Leukoencephalopathy, Progressive Multifocal	D007968	[An opportunistic viral infection of the central nervous system associated with conditions that impair cell-mediated immunity (e.g., ACQUIRED IMMUNODEFICIENCY SYNDROME and other IMMUNOLOGIC DEFICIENCY SYNDROMES; HEMATOLOGIC NEOPLASMS; IMMUNOSUPPRESSION; and COLLAGEN DISEASES). The causative organism is JC Polyomavirus (JC VIRUS) which primarily affects oligodendrocytes, resulting in multiple areas of demyelination. Clinical manifestations include DEMENTIA; ATAXIA; visual disturbances; and other focal neurologic deficits, generally progressing to a vegetative state within 6 months. (From Joynt, Clinical Neurology, 1996, Ch26, pp36-7)]
Demyelinating Diseases	D003711	[Diseases characterized by loss or dysfunction of myelin in the central or peripheral nervous system., The first region-restricted episode of CNS inflammatory demyelination in a patient. It is usually characterized by an acute monosymptomatic presentation of the optic nerves, brainstem, or spinal cord. It may not reoccur (isolated), or it may progress to MULTIPLE SCLEROSIS.]
Leukoencephalopathies	D056784	[Any of various diseases affecting the white matter of the central nervous system.]
Encephalitis, Viral	D018792	[Inflammation of brain parenchymal tissue as a result of viral infection. Encephalitis may occur as primary or secondary manifestation of TOGAVIRIDAE INFECTIONS; HERPESVIRIDAE INFECTIONS; ADENOVIRIDAE INFECTIONS; FLAVIVIRIDAE INFECTIONS; BUNYAVIRIDAE INFECTIONS; PICORNAVIRIDAE INFECTIONS; PARAMYXOVIRIDAE INFECTIONS; ORTHOMYXOVIRIDAE INFECTIONS; RETROVIRIDAE INFECTIONS; and ARENAVIRIDAE INFECTIONS.]
Leukoedema, Oral	D007967	[A disorder of the buccal mucosa resembling early leukoplakia, characterized by the presence of filmy opalescence of the mucosa in the early stages to a whitish gray cast with a coarsely wrinkled surface in the later stages, associated with intracellular edema of the spinous or malpighian layer. (Dorland, 27th ed)]
Mouth Diseases	D009059	[Diseases involving the MOUTH.]
Hypoglycemia	D007003	[HYPOGLYCEMIA expressed after a meal or FOOD INTAKE. It is also called reactive or stimulative hypoglycemia., HYPOGLYCEMIA expressed in the postabsorptive state, after prolonged FASTING, or an overnight fast., A syndrome of abnormally low BLOOD GLUCOSE level. Clinical hypoglycemia has diverse etiologies. Severe hypoglycemia eventually lead to glucose deprivation of the CENTRAL NERVOUS SYSTEM resulting in HUNGER; SWEATING; PARESTHESIA; impaired mental function; SEIZURES; COMA; and even DEATH.]
Hyperinsulinism	D006946	[A GLUCOSE-induced HYPERINSULINEMIA, a marker of insulin-resistant state. It is a mechanism to compensate for reduced sensitivity to insulin., A syndrome with excessively high INSULIN levels in the BLOOD. It may cause HYPOGLYCEMIA. Etiology of hyperinsulinism varies, including hypersecretion of a beta cell tumor (INSULINOMA); autoantibodies against insulin (INSULIN ANTIBODIES); defective insulin receptor (INSULIN RESISTANCE); or overuse of exogenous insulin or HYPOGLYCEMIC AGENTS.]
