Risk factors

Lichen nitidus seems to be more likely to develop in children and young adults.

Association with other diseases

Because lichen nitidus is rare, most information about the disorder is known from individual cases or small studies. Links between lichen nitidus and other diseases aren't well-understood, but they may include:

• Lichen planus, an inflammatory condition usually characterized by patches of red or purple, flat-topped, itchy bumps on the skin or lacy white patches on the mucous membranes of the mouth
• Atopic dermatitis (eczema), an inflammatory skin condition usually characterized by dry, itchy rashes on the face, inside the elbow, behind the knees, and on the hands and feet
• Crohn's disease, inflammation of the lining of your digestive tract, which can lead to abdominal pain, severe diarrhea and malnutrition
• Juvenile rheumatoid arthritis, an inflammatory disease that causes persistent joint pain, swelling and stiffness
• Tuberculosis, an infectious disease that most often affects the lungs
