Question: 1 / 400

How is a macule defined in dermatological terms?

A raised, palpable lesion

A flat, non-palpable skin color change

In dermatological terms, a macule is specifically defined as a flat and non-palpable change in skin color that is usually smaller than 1 cm in diameter. It does not involve any elevation or depression of the skin, making it distinct from other types of lesions. Macules can occur in a variety of colors, including red, brown, or hypopigmented areas, and are often seen in conditions like freckles, petechiae, or melasma. The defining characteristic is the lack of texture variation compared to the surrounding skin, which is crucial for proper classification in a dermatological context.

This choice effectively captures the essential attributes of a macule, distinguishing it from other lesions such as papules, which are raised and palpable, vesicles that contain fluid, and other forms of skin irritation, which may involve changes in texture or elevation.
