fa·vus (faґvəs) [L. “honeycombâ€] a type of ringworm seen in many different animals, caused by species of Trichophyton. In humans the fungus is usually T. schoenleinii and is in the scalp (tinea capitis), although it may also affect glabrous skin (tinea corporis). Yellow cup-shaped crusts form, called scutula, and may enlarge and coalesce to form honeycomblike masses; this may be associated with hair loss, cutaneous atrophy, and scarring. Called also honeycomb ringworm and tinea favosa.
