You are welcome. Regards.
Update: I visited the dermatologist a couple of days ago. The dermatologist pretty much repeated what Dr. Kaur Bhupinder responded to my original post. The mole was checked closely and found no abnormality. Thank you Dr. Bhupinder for your response.
Hello,
It can be a small cyst or lipoma under the mole. They may occur anywhere on body but scalp, ears, back, face, and upper arm, are common sites for sebaceous cysts. Blocked sebaceous glands, swollen hair follicles and excessive testosterone production will cause such cysts.
Since it is under a mole, hence get it evaluated from a dermatologist.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
