| benign ear cyst | A disorder where there are noncancerous lumps or growths within the ear canal or on the pinna of the ear (external ear). most lumps are sebaceous cysts but some are bony overgrowths known as exostoses (or osteomas). If large enough they may interfere with hearing. In this case surgical removal may be required. (27 Sep 1997) |
| benign essential tremor | A benign tremor inherited as a dominant character; it may be a rapid oscillation resembling that seen in thyrotoxicosis, a coarse tremor during rest and inhibited by a voluntary effort, or one which appears only upon movement. Synonym: benign essential tremor, familial tremor. (05 Mar 2000) |
| benign faint | A form of syncope (fainting) that occurs as a part of a normal physiologic response to stress (often emotional stress). The individual becomes lightheaded, nauseated, flushed, feels warm and then may lose consciousness for several seconds. (27 Sep 1997) |
| benign familial chorea | A rare, nonprogressive movement disorder characterised by chorea and athetosis appearing in early childhood, most commonly manifested as gait ataxia and upper limb coordination. Intellect is unaffected. Probably autosomal-dominance inheritance with incomplete penetrance. (05 Mar 2000) |
| benign familial chronic pemphigus | Recurrent eruption of vesicles and bullae that become scaling and crusted lesions with vesicular borders, predominantly of the neck, groin, and axillary regions; autosomal dominant inheritance, presenting in late adolescence or early adult life. Synonym: Hailey-Hailey disease. (05 Mar 2000) |
| benign familial icterus | Mild jaundice due to increased amounts of unconjugated bilirubin in the plasma without evidence of liver damage, biliary obstruction, or haemolysis; thought to be due to an inborn error of metabolism in which the excretion of bilirubin by the liver is defective, ascribed to decreased conjugation of bilirubin as a glucuronide or impaired uptake of hepatic bilirubin. Synonym: benign familial icterus, constitutional hepatic dysfunction, Gilbert's disease, Gilbert's syndrome, Hebra's disease. (05 Mar 2000) |
| benign giant lymph node hyperplasia | Solitary masses of lymphoid tissue containing concentric perivascular aggregates of lymphocytes, occurring usually in the mediastinum or hilar region of young adults; similar changes have been reported outside the mediastinum and, if associated with interfollicular sheets of plasma cells, may progress to lymphoma or plasmacytoma. Synonym: angiofollicular mediastinal lymph node hyperplasia, Castleman's disease. (05 Mar 2000) |
| benign glycosuria | Glycosuria not associated with diabetes mellitus but resulting from a low renal threshold for sugar. (05 Mar 2000) |
| benign headache | A benign form of headache that results from the painful spasm (muscle tightness) and inflammation of muscles of the head and neck. Tension headache is one of the most common forms of headache. Spasm and contraction of the head and neck muscles may occur in response to fatigue, overuse, eye strain, excessive smoking, stress, anxiety or depression. Sleeping in an abnormal position or prolonged work involving immobilisation of the neck in one position (typing, computers, etc.) are considered common triggers. Exercising and stretching the muscles of the head and neck can reduce the occurrence of muscle tension headaches. (27 Sep 1997) |
| benign hypertension | Hypertension that runs a relatively long and symptomless course. (05 Mar 2000) |
| benign inoculation lymphoreticulosis | <disease> A self-limiting bacterial infection of the regional lymph nodes (lymphadenitis) caused by afipia felis, a gram-negative bacterium recently identified as bartonella henselae. It usually arises one or more weeks following a feline scratch, with raised inflammatory nodules at the site of the scratch being the primary symptom. It results in tender and enlarged lymph glands above the site of injury. A chronic benign adenopathy, especially in children and young adults, commonly associated with a recent cat scratch or bite and caused by bacteria including Bartonella henselae and Alipia felis; the lymphadenopathy usually resolves spontaneously within a period of several months, but complications involving central nervous system, liver, spleen, lung, and skin have been seen. Synonym: benign inoculation lymphoreticulosis, benign inoculation reticulosis, cat-scratch fever, regional granulomatous lymphadenitis. (05 Mar 2000) |

| benign juvenile melanoma | A benign, slightly pigmented or red superficial small skin tumour composed of spindle-shaped, epithelioid, and multinucleated cells that may appear atypical; most common in children, but also appearing in adults. Synonym: benign juvenile melanoma, epithelioid cell nevus, spindle cell nevus. (05 Mar 2000) |
