A severe, unremitting type of chronic ringworm of the scalp and nails, with scarring and formation of crusts called scutula, caused by three dissimilar dermatophytes, Trichophyton schoenleinii (most commonly), T. violaceum, and Microsporum gypseum; it occurs more frequently in the Mediterranean countries, southeastern Europe, southern Asia, and northern Africa.
favus/fa·vus/ (fa´vus) a type of tinea, usually of the scalp but sometimes affecting glabrous skin, with formation of scutula, which may enlarge and coalesce to form prominent honeycomb-like masses; due to infection by the fungus Trichophyton, usually T. schoenleinii.
A chronic skin infection, usually of the scalp, caused by fungi of the genus Trichophyton and characterized by the development of thick, yellow crusts over the hair follicles.
Etymology: L, honeycomb
a fungal infection of the scalp, skin, or nails, more common in children than adults. It is caused by Trichophyton fungi. Favus is characterized by thick yellow crusts with suppuration, a honeycomb appearance, a distinct "mousy" odor, permanent scars, and alopecia. It is rarely seen in North America but is common in the Middle East and Africa.
favusA disfiguring scalp dermatophytosis caused by Trichophyton violaceum and Microsporum gypseum, with destruction of hair follicles and alopecia
A severe type of chronic ringworm of the scalp and nails; it occurs more frequently in Mediterranean countries, southeastern Europe, southern Asia, and northern Africa. Differences in severity are related to hygiene.
favusA persistent infection of the hair follicles, especially of the scalp (tinea capitis), caused by the fungus Trichophyton schoenleinii . Characteristic crusts form and in the long term there is widespread loss of hair from scarring. From Latin, favus , a honeycomb.
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.
