My 9-year-old son has a painless bump on his penis for two months. How to get rid of it?

Hi,

Welcome to icliniq.com.

Crusted lesion (of short duration) over the penis in childhood can be due to frictional dermatitis, allergy and Scabies. In some conditions where there is heaping up of dead skin, it causes this scaly lesion. I suggest the following methods to take care of it. For short-duration lesions you should maintain local hygiene, clean the area with lukewarm water and hypoallergenic soap, followed by applying a gentle moisturizer twice daily to soften the crust. You should avoid tight-fitting clothes or any type of rubbing or friction. In some cases like allergic contact dermatitis, a mild steroid cream (Hydrocortisone 1 percent) can be applied locally for a short time (one week). Other conditions can cause this type of skin lesion like penile infection, psoriasis, etc. So you need to get a proper clinical evaluation done by your physician to know what is causing this crusted lesion. Some tests can also be done, like microscopic examination or dermoscopy, to diagnose the condition.
