Once in a while I get this small bump on

Patient: Once in a while I get this small bump on my penis that eventually grows and fills with puss. Its gone within like 5 days. Is it a sabaceous cyst?

Doctor: Hi.Thanks for your query.The bump on the penis which is recurrent, small, goes within 5 days and comes again is m ost probably a small sebaceous cyst. The automatic opening or the popping is not removing the internal lining of the cyst wall.If this recurs again, consult a Dermatologist or a Surgeon and get the whole cyst removed.I hope this answer helps you.
