Wood's lamp (blacklight) examination will reveal a bright green to yellow-green fluorescence of hairs infected by Trichophyton mentagrophytes var. Mentagrophytes, in kerion infection caused by Trichophyton verrucosum Invaded hairs show an ectothrix infection and fluorescence under Wood's ultra-violet light has been noted in cattle but not in ...
Tinea versicolor (also known as dermatomycosis furfuracea, pityriasis versicolor, and tinea flava) [2] is a condition characterized by a skin eruption on the trunk and proximal extremities, hypopigmentation macule in area of sun induced pigmentation. During the winter the pigment becomes reddish brown.
Dermatophytosis, also known as tinea and ringworm, is a fungal infection of the skin [2] (a dermatomycosis), that may affect skin, hair, and nails. [1] Typically it results in a red, itchy, scaly, circular rash. [1]
However, a simple side-room investigation with a Wood's lamp is additionally useful in diagnosing erythrasma. [4] The ultraviolet light of a Wood's lamp causes the organism to fluoresce a characteristic coral red color, differentiating it from other skin conditions such as tinea versicolor, which may fluoresce a copper-orange color. [5]
During this process, a lamp that uses long-wave ultraviolet (UV) light will make certain cells show color or appear fluorescent, according to the Cleveland Clinic. Doctors also take time during ...
Endothrix refers to dermatophyte infections of the hair that invade the hair shaft and internalize into the hair cell. This is in contrast to exothrix (ectothrix), where a dermatophyte infection remains confined to the hair surface.
Tinea capitis is often treated with oral antifungal medications, but antifungal shampoos — like ketoconazole shampoo — may be used as part of a treatment plan. So, if your hair loss is caused ...
