Kindly suggest the cause and treatment for the colorless bumps on my arms.

Hi,

Welcome to icliniq.com.

I have gone through the picture (attachment removed to protect patient identity). These tiny skin colored papules are called lichen nitidus. It is a harmless condition. In about 70 % of cases, it is self-limiting which means it resolves on its own, no treatment is usually required. If it is itchy, then use Mometasone cream, mix one part of cream with two parts of moisturizer and apply a thin layer to the affected area at night for two weeks only. Mometasone is a moderately potent topical corticosteroid. It should not be used continuously. Use it for two weeks. Take a break for a week then again use it for another two weeks if the skin lesions are still present. Olesoft moisturizing lotion (Olive oil with Sodium lactate) is fine. You can use any moisturizer or lotion but do not use cream or ointment because the ointment will be thick and can clog the pores. It is better to use lotion during summer.

Hi,

Welcome back to icliniq.com.

Lichen nitidus is an idiopathic condition where the exact cause is not known. There is a specific hypothesis which shows that it is linked to lichen planus in 25 % of cases, which is a chronic inflammatory condition. If the lesions are spreading, then you can use Mometasone as instructed. Otherwise, it is a self-limiting condition, and no treatment is needed. It is not contagious, and it does not spread from person to person.
