Which of the following is classified as abnormal inflammation?

• A. Hospital acquired infections
• B. Severe bruising
• C. Chronic inflammation disorders
• D. Localized cellulitis

Answer: (C)

Chronic inflammation disorders are classified as abnormal inflammation because they represent a prolonged inflammatory response that can lead to tissue damage and a variety of health complications. Normally, inflammation is a physiological response to injury or infection, aimed at healing the tissue and resolving the harmful stimuli. However, in chronic inflammation, the immune system remains activated over an extended period, often due to unresolved infections, persistent irritants, or autoimmune conditions, leading to continuous tissue injury and repair processes that can overwhelm the normal healing mechanisms.

In contrast, hospital-acquired infections, severe bruising, and localized cellulitis represent situations in which inflammation may be considered part of a normal response to acute injury or infection. While they can cause discomfort and require treatment, they do not exhibit the prolonged characteristics that define chronic inflammation. Instead, these conditions typically invoke a more localized and transient inflammatory response aimed at resolving the specific issue at hand.
