Lichen nitidus is a rare, non-cancerous, inflammatory skin condition. It causes tiny, raised, itchy bumps (papules) on the skin, usually on the arms and legs. These papules typically appear in clusters. Lichen nitidus most often occurs in children and young adults.
Lichenoid Dermatoses is a chronic skin eruption characterized by hardening and thickening of the skin with the accentuation of normal skin markings.
Lichen planus is a benign, common disease that affects the skin, nails, and/or mouth. It affects about 1% of the general population. To understand what lichen planus (LP) is, it's important to note what the disease is not. Lichen planus is not an infectious disease. It is impossible to "catch" lichen planus from someone who has it or to give it to someone else. The disease is not a form of cancer, it does not appear to be inherited, and it is not related to nutrition.
Lichen striatus is a rash that consists of small raised bumps in a line, which gradually fade leaving a line of flat, white, pink or brown spots. These spots usually fade with time, leaving flat white or dark spots. These lesions last one week to three years, then spontaneously disappear. Characteristically, the lesions begin on a buttock and spread down the leg, or begin on the shoulder and progress down the arm, but they can occur anywhere on the face or body. If the lesions are present on a finger or toe, the nail may appear abnormal.
