Which condition is characterized by an acute inflammatory pus forming skin infection?

The condition characterized by an acute inflammatory pus-forming skin infection is pyoderma. This term specifically refers to any skin infection that results in the production of pus, typically caused by bacterial infection. The inflammation associated with pyoderma can lead to various symptoms such as redness, swelling, pain, and the formation of pustules or abscesses.

Pyoderma is notable for its clear acute inflammatory response, which distinguishes it from other dermatological conditions. For instance, dermatitis generally refers to skin inflammation without a pus-producing infection. Psoriasis is a chronic skin condition marked by rapid skin cell turnover leading to thickened, scaly patches and is not characterized by pus formation. Folliculitis involves inflammation of hair follicles and can produce pus, but it is more localized compared to pyoderma, which can affect larger areas of the skin and signify a more systemic infection. Therefore, pyoderma is the most appropriate answer when looking for a condition that specifically denotes a pus-forming infectious process on the skin.
