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).
