Thanks for the query.
This presentation can be seen with many diseases. This is limited information to make precise recommendations. The best option is to consult a Dermatologist to understand the condition. A thorough evaluation if necessary should be done. A photograph of the affected area will help you get better recommendations. Hope it helps you.
