There are lots of people who have lumps on their body for many years and are not aware what those lumps contain inside just until they visit a dermatologist.
Dr. Sandra Lee is dermatologist and is also known as Dr. Pimple Pooper because for years she treats pimples. One day, one elderly woman came to see her because she had a giant pimple on her back. At the beginning, Dr. Lee thought that she had giant blackhead.
But as it seemed, it wasn’t. Actually it was epidermoid cyst also known as keratin cyst. This cyst is round and it does looks like blackhead. The doctor recorded the cyst removal and that video was viewed on YouTube more than 1.6 million times.
