| 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).

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) |

(12 Dec 1998) |

| pemphigoid, benign mucous membrane | A chronic blistering disease with predilection for mucous membranes and less frequently the skin, and with a tendency to scarring. It is sometimes called ocular pemphigoid because of conjunctival mucous membrane involvement. (12 Dec 1998) |
| pemphigus, benign familial | Rare hereditary disease characterised by recurrent eruptions of vesicles and bullae mainly on the neck, axillae, and groin. It exhibits autosomal dominant inheritance and is unrelated to pemphigus vulgaris though it closely resembles that disease. (12 Dec 1998) |
