inflammatory skin condition resembling lichen planus with itchy bumps

A Lichenoid Reaction, also known as Lichenoid Dermatitis, is an inflammatory skin condition characterized by a rash that resembles lichen planus. It often presents as small, itchy, purple or red bumps on the skin and can be triggered by medications, infections, or autoimmune diseases. This reaction involves an immune response where T-cells attack the skin, leading to damage and inflammation.
