GlossaryLichenoid Reaction

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.

in Research 692 upvotes 4 months ago

Scalp biopsies are crucial for diagnosing hair loss conditions like Diffuse Unpatterned Alopecia (DUPA) and retrograde hair loss, as treatments like finasteride and dutasteride may not be effective if other conditions are present. Combining PPAR-GAMMA agonists with retinoids could improve treatments for conditions like Lichen Planopilaris.
