What is a raised lesion with a flat surface called?

A raised lesion with a flat surface is called a plaque. This term describes a specific type of skin lesion that is typically elevated above the surrounding skin but has a broad, flat surface. Plaques can vary in size and may be composed of various materials, including keratin or other tissues, leading to differing textures and appearances.

Understanding the characteristics of plaques is essential for estheticians as it helps in identifying various skin conditions. For example, conditions such as psoriasis often present with plaques, which can aid in assessing skin health and determining appropriate treatments. Recognizing the raised but flat nature of plaques differentiates them from other types of skin lesions, such as nodules, which are solid and raised but not necessarily flat on top. This distinction is important in effective communication and treatment within the field of esthetics.
