favus
a disease of fowls caused by Microsporum gallinae. Small white patches appear on the comb, then coalesce and thicken. If lesions spread to feathered parts typical favus shield-like scabs are formed. In long-standing cases scabs on the skin of the neck may be packed close together and, with their depressed centers, give a honeycomb appearance, hence the name honeycomb ringworm.
