Thanks for the query.
This presentation can be seen with many skin diseases. The best option is to consult a Dermatologist. Moles are usually benign in our country but any change in shape, size and colour should warrant an examination and if needed a skin biopsy should be performed without hesitation. It is always reassuring to get a diagnosis and feel comfortable about the same. Hope it helps you.
Your dermatologist will decide a treatment plan for you after a consultation.
