###Human: I notice some tiny brown spots while loosening my foreskin. What could it be? ###Assistant: Hi. I have gone through your case. In my opinion, there are two to three different diagnoses. 1. Plane warts which are vital infection and mostly acquired sexually. The treatment of this is fulguration or cautery. 2. Lentigenes or freckles which usually require no treatment. 3. Normal variant. Moreover, Betamethasone has nothing to do with these brown spots. There is no urgency but see dermatologist physically for one of the above-confirmed diagnosis.
