An ulcer is best described as a deeper lesion that is often rounded or irregularly shaped. This type of lesion represents a breach in the skin or mucous membrane, which can be caused by various factors such as infections, pressure, or inflammatory conditions. Ulcers typically extend beyond the superficial layers, affecting the deeper tissues and can often present with a characteristic base that may be covered by necrotic tissue or exudate. Understanding the nature of ulcers is essential for proper diagnosis and treatment, especially in the context of tattooing and skin integrity, as they may affect healing and the overall health of the skin being tattooed.

The other options describe different skin conditions or features: a small fluid-containing blister refers to a vesicle, a type of scale involves flaking or peeling of the skin, and a linear cleft suggests a fissure, which is distinct from the broader and deeper form of a lesion like an ulcer. Each of these terms points to specific characteristics that do not encompass the defining traits of an ulcer.
