Which skin condition is characterized by warm, erythematous, and tender skin?

Cellulitis is characterized by warm, erythematous (red), and tender skin. This condition is a bacterial skin infection that typically affects the deeper layers of the skin, specifically the dermis and subcutaneous tissue. The warmth of the affected area is a result of increased blood flow as the body's immune response reacts to the infection. Tenderness and pain are also common as the infection causes inflammation and irritation in the tissues.

In contrast, impetigo often presents with honey-colored crusted lesions and is typically located on the surface of the skin; folliculitis is an inflammation of hair follicles that may also be red but is usually not associated with the same degree of systemic infection signs; scabies is caused by an infestation of mites and presents with intense itching and a rash, primarily involving the webs between fingers and other skin folds without significant warmth or tenderness.
