; any of numerous different fungal infections of the skin; the specific type (depending on characteristic appearance, etiologic agent and site) usually is designated by a modifying term.
ringworm of the beard, seen on bearded parts of the face and neck; caused by Trichophyton.
ringworm of the scalp, a fungal infection caused by various species of Microsporum
Generally it is characterized by one or more small, round, elevated patches, scaling of the scalp, and dry and brittle hair.
a fungal infection of the glabrous (smooth) skin, usually due to species of Microsporum
ringworm of the face, seen on non-hairy areas of the face, often with a similar presentation to that of tinea corporis
a distinctive type of tinea corporis
occurring in tropical countries and caused by Trichophyton concentricum.
The early lesion is circular, surrounded by a ring of scales attached along one edge; several new and larger scaling rings form later.
) ringworm of the hand, usually involving the interdigital spaces and palmar surfaces of the hands; it almost always accompanies tinea pedis
, with the same etiologic agent for both infections.
tinea un´guium tinea involving the nails; the invasion may be restricted to white patches or pits on the nail surface, or the lateral or distal edges of the nail may be involved first, followed by establishment of the infection beneath the nail plate.
a chronic, usually asymptomatic disorder due to Malassezia furfur,
marked only by multiple macular patches. Called also pityriasis versicolor

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.
tinea barbaeBarber's itch.
A fungal infection of the scalp. It may be due to one of several types of Microsporum or to Trichophyton tonsurans. See: illustration; kerion
Tinea of the body. It begins with red, slightly elevated scaly patches that on examination reveal minute vesicles or papules. New patches spring from the periphery while the central portion clears. There is often considerable itching. See: illustration
A fungus skin disease of surfaces of contact in the scrotal, crural, anal, and genital areas. Synonym: dhobie itch; jock itch See: illustration
Chronic tinea caused by Trichophyton concentricum. It is present in tropical regions. The annular lesions have scales at their periphery.
Tinea corporis that grows rapidly and in unusual patterns after the use of topical steroids.
An asymptomatic superficial fungal infection that affects the skin of the palms. Caused by Hortaea werneckii, it is characterized by deeply pigmented, macular, nonscaly patches. Synonym: pityriasis nigra
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. The masses surround the hairs, which become brittle; hairs may be penetrated by fungus and thus split. Synonym: piedra
tinea pedisAthlete's foot.
tinea profundaMajocchi's disease.
tinea sycosisBarber's itch (2).
tinea tonsurans Tinea capitis.
TINEA VERSICOLOR (on back)
TINEA VERSICOLOR (on back)
A fungus infection of the skin producing yellow or fawn-colored branny patches. A topically applied azole antifungal cream or 2% selenium sulfide lotion is effective in treating the causative agent, the fungus Malassezia furfur. Synonym: pityriasis versicolor See: illustrationillustration
