Tinea corporis

This term covers infections of the trunk and limbs with characteristic annular or ring-like lesions which are usually unilateral. They appear as pink scaly plaques or papules which extend outwards and heal form the centre (Figure 12.8). The degree of inflammation depends on whether the infection is anthrophilic, for example T. rubrum or tonsurans when the lesions are usually less erythematous, or zoophilic, for example Μ. canis, which produces erythematous scaly lesions (Clayton, 2000). It is common in children of all ages and adults but rare cases have been seen in the newborn.
