Tinea corporisThis is the typical ‘ringworm’ of
the trunk and limbs and appears as a slowly
growing, roughly annular (ring-like) lesion with a
slightly raised and inflamed, reddened, well-defined
leading edge (Figure 1a). The degree of itchiness
patients describe is variable. The lesion may
initially be solitary, but over time other similar
lesions usually develop and older plaques start to
show central healing. Lesions may coalesce. Most
lesions have fine scales, especially at the leading
edge, where the fungus is actively invading the
keratin layers of the skin. All such patients should
be checked for other sites of infection, particularly
the groin and feet (Noble et al1998).
