Definition
The key characteristic of Tinea corporis is that the fungus involves the glabrous (relatively hairless) skin. The infection is limited to the stratum corneum of the epidermis. Vellus hair (the fine hair present on glabrous skin) may be invaded, and the hair follicle may serve as a reservoir for the fungus. Tinea pedis,Tinea manuum, and Tinea cruris refer to Tinea corporis that is limited to the foot, hand, and groin, respectively. There is otherwise little special about them. History lesson: The term tinea has an interesting origin. A worm of a moth would sometimes grow on a woolen blanket. The resulting round holes were similar to the rounded lesions seen on the skin of patients. The genus name for the moth was Tinea, and thus this name was used as part of the Latin binomials naming these infections.
