True or False: Dry gangrene exhibits a poorly defined line of demarcation.

Dry gangrene typically presents a clear and well-defined line of demarcation between healthy and necrotic tissue. This is a key characteristic that distinguishes it from other forms of gangrene, such as wet gangrene, which often lacks such clear boundaries due to the presence of infection and fluid. In dry gangrene, the tissue becomes dry, black, and shriveled, and this process usually occurs gradually, allowing for the development of this clear demarcation.

Understanding this distinction is essential in the field of wound care and necessary for proper diagnosis and treatment. The presence of a well-defined line indicates that the necrosis is localized and that surrounding healthy tissue can often remain viable, which is critical for clinical decision-making regarding interventions like surgical amputation or wound management.
