Label	Id	Description
Histiocytic Necrotizing Lymphadenitis	D020042	[Development of lesions in the lymph node characterized by infiltration of the cortex or paracortex by large collections of proliferating histiocytes and complete or, more often, incomplete necrosis of lymphoid tissue.]
Lymphadenitis	D008199	[Inflammation of the lymph nodes.]
Illusions	D007088	[The misinterpretation of a real external, sensory experience.]
Perceptual Disorders	D010468	[Cognitive disorders characterized by an impaired ability to perceive the nature of objects or concepts through use of the sense organs. These include spatial neglect syndromes, where an individual does not attend to visual, auditory, or sensory stimuli presented from one side of the body.]
Ephemeral Fever	D004810	[An Ephemerovirus infection of cattle caused by bovine ephemeral fever virus (EPHEMERAL FEVER VIRUS, BOVINE). It is characterized by respiratory symptoms, increased oropharyngeal secretions and lacrimation, joint pains, tremor, and stiffness.]
Tetrasomy	D058670	[The possession of four chromosomes of any one type in an otherwise diploid cell.]
Epidermal Cyst	D004814	[Intradermal or subcutaneous saclike structure, the wall of which is stratified epithelium containing keratohyalin granules.]
Chromosome Aberrations	D002869	[Abnormal number or structure of chromosomes. Chromosome aberrations may result in CHROMOSOME DISORDERS.]
Epidermodysplasia Verruciformis	D004819	[An autosomal recessive trait with impaired cell-mediated immunity. About 15 human papillomaviruses are implicated in associated infection, four of which lead to skin neoplasms. The disease begins in childhood with red papules and later spreads over the body as gray or yellow scales.]
Warts	D014860	[Benign epidermal proliferations or tumors; some are viral in origin.]
Epidermitis, Exudative, of Swine	D004818	[An acute generalized dermatitis of pigs which occurs from 5 to 35 days of age, characterized by sudden onset, with morbidity of 10 to 90% and mortality of 5 to 90%. The lesions are caused by Staphylococcus hyos but the bacterial agent is unable to penetrate the intact skin. Abrasions on the feet and legs or lacerations on the body frequently precede infection. In acute cases, a vesicular-type virus may be the predisposing factor. The causative organism is inhibited by most antibiotics. (Merck Veterinary Manual, 5th ed)]
Prodromal Symptoms	D062706	[Clinical or physiological indicators that precede the onset of disease., Time marking early onset of disease, Early onset of symptoms, Early event in disease onset]
Smith-Lemli-Opitz Syndrome	D019082	[An autosomal recessive disorder of CHOLESTEROL metabolism. It is caused by a deficiency of 7-dehydrocholesterol reductase, the enzyme that converts 7-dehydrocholesterol to cholesterol, leading to an abnormally low plasma cholesterol. This syndrome is characterized by multiple CONGENITAL ABNORMALITIES, growth deficiency, and INTELLECTUAL DISABILITY.]
Steroid Metabolism, Inborn Errors	D043202	[Errors in metabolic processing of STEROIDS resulting from inborn genetic mutations that are inherited or acquired in utero.]
Epidermolysis Bullosa	D004820	[Group of genetically determined disorders characterized by the blistering of skin and mucosae. There are four major forms: acquired, simple, junctional, and dystrophic. Each of the latter three has several varieties.]
Cafe-au-Lait Spots	D019080	[Light brown pigmented macules associated with NEUROFIBROMATOSIS and Albright's syndrome (see FIBROUS DYSPLASIA, POLYOSTOTIC).]
Polymyalgia Rheumatica	D011111	[A syndrome in the elderly characterized by proximal joint and muscle pain, high erythrocyte sedimentation rate, and a self-limiting course. Pain is usually accompanied by evidence of an inflammatory reaction. Women are affected twice as commonly as men and Caucasians more frequently than other groups. The condition is frequently associated with GIANT CELL ARTERITIS and some theories pose the possibility that the two diseases arise from a single etiology or even that they are the same entity.]
Tetralogy of Fallot	D013771	[A combination of congenital heart defects consisting of four key features including VENTRICULAR SEPTAL DEFECTS; PULMONARY STENOSIS; RIGHT VENTRICULAR HYPERTROPHY; and a dextro-positioned AORTA. In this condition, blood from both ventricles (oxygen-rich and oxygen-poor) is pumped into the body often causing CYANOSIS.]
Epididymitis	D004823	[Inflammation of the EPIDIDYMIS. Its clinical features include enlarged epididymis, a swollen SCROTUM; PAIN; PYURIA; and FEVER. It is usually related to infections in the URINARY TRACT, which likely spread to the EPIDIDYMIS through either the VAS DEFERENS or the lymphatics of the SPERMATIC CORD.]
Coronary-Subclavian Steal Syndrome	D058686	[A complication of INTERNAL MAMMARY-CORONARY ARTERY ANASTOMOSIS whereby an occlusion or stenosis of the proximal SUBCLAVIAN ARTERY causes a reversal of the blood flow away from the CORONARY CIRCULATION, through the grafted INTERNAL MAMMARY ARTERY (internal thoracic artery), and back to the distal subclavian distribution.]
