What word refers to a skin lesion with a wavy margin, often seen in ringworm?

The term "serpiginous" accurately describes a skin lesion characterized by a wavy margin, commonly associated with infections like ringworm. This term originates from the Latin word “serpens,” meaning snake, which aptly conveys the appearance of the lesion resembling a snake or a winding path. In the context of dermatology, serpiginous lesions typically exhibit irregular borders and can be indicative of various dermatological conditions, including fungal infections.

While "linear" refers to lesions that have a straight line appearance, and "scaly" describes the texture or condition of the skin surface without reference to shape, "vesicular" pertains to fluid-filled blisters. None of these terms capture the specific wavy margin characteristic seen in ringworm lesions, making "serpiginous" the most accurate choice for describing such skin conditions.
