Dr. Sandra Lee is a popular dermatologist known as Dr. Pimple Popper who has a YouTube channel which shows some of her treatments. Although she is used to seeing pimples, she was stunned when an older woman came to her office with a gigantic pimple on her back!
In the start, Dr. Lee though that it was just a blackhead, but it was actually an epidermoid cyst, a benign cyst which grows out of the ectodermal tissue and is also known as a keratin cyst. The cyst was round and flat, looking like a blackhead. The video below shows Dr. Lee removing the cyst and has been viewed over 1.6 million times on YouTube. But, be wary – it is not for the faint hearted!
