The full form of LLP disease is Linear Lichen Planus.
Linear lichen planus is a rare variant of lichen planus, a skin condition that can affect the skin and mucous membranes (like the inside of the mouth). In LLP, the characteristic itchy, purple, flat-topped bumps (papules) arrange themselves in a linear fashion, often following Blaschko's lines – invisible patterns of skin cell development.
Here's a breakdown:
- Linear: Refers to the arrangement of the rash in a line.
- Lichen Planus: A chronic inflammatory condition affecting the skin, mouth, and sometimes other areas.
Therefore, LLP describes the specific presentation of lichen planus where the rash appears in a linear pattern.
