Linear ulcers are commonly referred to as fissures. Fissures are characterized by narrow, linear breaks or splits in the skin or mucous membranes, often caused by various factors such as trauma, infections, or inflammatory conditions. In the context of linear ulcers, the term "fissure" is particularly relevant because it denotes the specific shape and form of the ulcer, which aligns with the characteristics of a linear presentation.

The other terms listed have distinct meanings in dermatology and do not describe linear ulcers accurately. Sinuses typically refer to abnormal passages or cavities that can be filled with pus, while impetigo is a contagious skin infection often characterized by blisters and crusted lesions. Cysts are sac-like structures that can contain fluid, air, or other substances, and they do not correspond to the linear nature of an ulcer. Understanding these distinctions is crucial for accurately identifying and referring to different skin conditions.
