tinea (tin'e-a ) [L. tinea, bookworm]
Any fungal skin disease occurring on various parts of the body. See: dermatomycosis
There are two types of findings. Superficial findings are marked by scaling, slight itching, reddish or grayish patches, and dry, brittle hair that is easily extracted with the hair shaft. The deep type is characterized by flat, reddish, kerion-like tumors, the surface studded with dead or broken hairs or by gaping follicular orifices. Nodules may be broken down in the center, discharging pus through dilated follicular openings.
Griseofulvin, terbinafine, or ketoconazole is given orally for all types of true trichophyton infections. Local treatment alone is of little benefit in ringworm of the scalp, nails, and in most cases the feet. Topical preparations containing fungicidal agents are useful in the treatment of tinea cruris and tinea pedis.
Personal hygiene is important in controlling these two common diseases. The use of antiseptic foot baths to control tinea pedis does not prevent spread of the infection from one person to another. Persons affected should not let others use their personal items such as clothes, towels, and sports equipment.
Tinea of the scalp, tinea capitis, is particularly resistant if due to Microsporum audouinii. It should not be treated topically. Systemic griseofulvin is quite effective.
Sticky scaling of the scalp following infection or trauma.

Sheathlike nodular masses in the hair of the beard and mustache from growth of either Piedraia hortae, which causes black piedra, or Trichosporon beigelii, which causes white piedra.
