Hello,
A sebaceous cyst is a closed sac occurring just under the skin which contains a "pasty" looking substance called keratin.They may occur anywhere on body but scalp, ears, back, face, and upper arm, are common sites for sebaceous cysts.Generally no treatment is required but they become painful then it means they are infected.If you want to remove it then surgical excision by traditional wide excision, minimal excision, and punch biopsy excision may be required.

I sincerely advise you to consult a dermatologist and discuss these options with him.
I hope that helps. Take care and pls do keep me posted on how you are doing or if you have any additional queries. Kind regards.
