What characteristic lesion is associated with erythema multiforme?

The characteristic lesion associated with erythema multiforme is indeed target-like lesions, which are often described as having a concentric, ringed appearance with multiple colors. This morphologic feature can resemble a "target" or "bull's-eye," with a central area of blistering or a necrotic zone surrounded by an edematous halo and then a darker red outer ring.

These target lesions typically appear on the palms, soles, and other surfaces of the body, making them distinct to erythema multiforme. This skin condition can arise in response to various triggers, including infections, medications, or other underlying diseases, and its manifestation with these characteristic lesions helps in clinical diagnosis.

Other options listed do not align with the typical findings in erythema multiforme. For example, pale, flat lesions are more characteristic of other conditions, such as vitiligo or pityriasis rosea. Raised nodules on the face do not match the description of erythema multiforme, as this condition usually does not present with such nodular lesions. Small vesicular lesions on the trunk might indicate other dermatoses, such as varicella or herpes simplex, rather than erythema multiforme. This
