What word refers to a skin lesion with a wavy margin, commonly seen in conditions like ringworm?

1. Serrated

2. Serpiginous

3. Linear

4. Undulated

The correct answer is: Serpiginous

The term that refers to a skin lesion with a wavy margin is "serpiginous." This word is used to describe skin lesions that have a snake-like or wavy appearance, often associated with conditions such as ringworm (tinea). The characteristics of serpiginous lesions include not only their wavy edges but also their tendency to create patterns that can expand over time, resembling serpents or sinuous paths. Understanding this term is crucial for skin condition assessment, as it provides insight into the nature and potential etiology of the lesion. Clinical observations often lead practitioners to consider specific dermatologic conditions based on the morphology of the lesions, enabling more accurate diagnosis and treatment planning. Other options like "serrated," "linear," and "undulated" describe different characteristics or shapes that do not specifically convey the wavy, serpent-like quality that the term "serpiginous" encapsulates. "Serrated" typically relates to jagged edges, "linear" pertains to straight lines, and "undulated" can imply a wave-like form but doesn’t convey the specific, wavy outline associated with conditions like ringworm. Thus, serpiginous is the most accurate and relevant term in this context.
