Label	Id	Description
Foot Ulcer	D016523	[Lesion on the surface of the skin of the foot, usually accompanied by inflammation. The lesion may become infected or necrotic and is frequently associated with diabetes or leprosy.]
Adiposis Dolorosa	D000274	[A rare disease characterized by multiple tumor-like fatty deposits that press on nerves in various sites causing pain and weakness. Often these lipoma-like structures are located on the trunk and limbs but not on the face and hands.]
Adie Syndrome	D000270	[A syndrome characterized by a TONIC PUPIL that occurs in combination with decreased lower extremity reflexes. The affected pupil will respond more briskly to accommodation than to light (light-near dissociation) and is supersensitive to dilute pilocarpine eye drops, which induce pupillary constriction. Pathologic features include degeneration of the ciliary ganglion and postganglionic parasympathetic fibers that innervate the pupillary constrictor muscle. (From Adams et al., Principles of Neurology, 6th ed, p279)]
Tonic Pupil	D015845	[A pupillary abnormality characterized by a poor pupillary light reaction, reduced accommodation, iris sector palsies, an enhanced pupillary response to near effort that results in a prolonged, "tonic" constriction, and slow pupillary redilation. This condition is associated with injury to the postganglionic parasympathetic innervation to the pupil. (From Miller et al., Clinical Neuro-Ophthalmology, 4th ed, pp492-500)]
Unilateral Breast Neoplasms	D000069584	[Tumors or cancer found specifically in the human left BREAST., Tumors or cancer found specifically in one human BREAST, but not in both., Tumors or cancer found specifically in the human right BREAST.]
Confusion	D003221	[A mental state characterized by bewilderment, emotional disturbance, lack of clear thinking, and perceptual disorientation.]
Gingival Hypertrophy	D005886	[Abnormal enlargement or overgrowth of the gingivae brought about by enlargement of existing cells.]
Gingival Neoplasms	D005887	[New abnormal growth of tissue in the GINGIVA.]
Gingival Hemorrhage	D005884	[The flowing of blood from the marginal gingival area, particularly the sulcus, seen in such conditions as GINGIVITIS, marginal PERIODONTITIS, injury, and ASCORBIC ACID DEFICIENCY.]
Gingival Hyperplasia	D005885	[Non-inflammatory enlargement of the gingivae produced by factors other than local irritation. It is characteristically due to an increase in the number of cells. (From Jablonski's Dictionary of Dentistry, 1992, p400)]
Retinopathy of Prematurity	D012178	[A bilateral retinopathy occurring in premature infants treated with excessively high concentrations of oxygen, characterized by vascular dilatation, proliferation, and tortuosity, edema, and retinal detachment, with ultimate conversion of the retina into a fibrous mass that can be seen as a dense retrolental membrane. Usually growth of the eye is arrested and may result in microophthalmia, and blindness may occur. (Dorland, 27th ed)]
Gingival Pocket	D005888	[An abnormal extension of a gingival sulcus not accompanied by the apical migration of the epithelial attachment.]
Gingivitis	D005891	[Inflammation of gum tissue (GINGIVA) without loss of connective tissue.]
Gingival Recession	D005889	[Exposure of the root surface when the edge of the gum (GINGIVA) moves apically away from the crown of the tooth. This is common with advancing age, vigorous tooth brushing, diseases, or tissue loss of the gingiva, the PERIODONTAL LIGAMENT and the supporting bone (ALVEOLAR PROCESS).]
Periodontal Atrophy	D055093	[Degradation or wasting of the PERIODONTIUM tissues that may involve the gum (GINGIVA), the alveolar bone (ALVEOLAR PROCESS), the DENTAL CEMENTUM, or the PERIODONTAL LIGAMENT.]
Retinoblastoma	D012175	[A malignant tumor arising from the nuclear layer of the retina that is the most common primary tumor of the eye in children. The tumor tends to occur in early childhood or infancy and may be present at birth. The majority are sporadic, but the condition may be transmitted as an autosomal dominant trait. Histologic features include dense cellularity, small round polygonal cells, and areas of calcification and necrosis. An abnormal pupil reflex (leukokoria); NYSTAGMUS, PATHOLOGIC; STRABISMUS; and visual loss represent common clinical characteristics of this condition. (From DeVita et al., Cancer: Principles and Practice of Oncology, 5th ed, p2104)]
Retinal Neoplasms	D019572	[Tumors or cancer of the RETINA.]
Laryngopharyngeal Reflux	D057045	[Back flow of gastric contents to the LARYNGOPHARYNX where it comes in contact with tissues of the upper aerodigestive tract. Laryngopharyngeal reflux is an extraesophageal manifestation of GASTROESOPHAGEAL REFLUX., GASTROESOPHAGEAL REFLUX wherein the retrograde flow passes through the UPPER ESOPHAGEAL SPHINCTER]
Gastroesophageal Reflux	D005764	[Retrograde flow of gastric juice (GASTRIC ACID) and/or duodenal contents (BILE ACIDS; PANCREATIC JUICE) into the distal ESOPHAGUS, commonly due to incompetence of the LOWER ESOPHAGEAL SPHINCTER.]
Retrocochlear Diseases	D012181	[Pathological processes involving the VESTIBULOCOCHLEAR NERVE; BRAINSTEM; or CENTRAL NERVOUS SYSTEM. When hearing loss is due to retrocochlear pathology, it is called retrocochlear hearing loss.]
