Healthy 29-year-old woman here. I have a one-inch hard nodule under the skin on my left cheekbone. It has grown from the size of a pea one year ago, when I first noticed it. It is mobile under the skin, has irregular shaping but it generally saucer shaped, and was diagnosed by three dermatologists as a sebaceous cyst. However, my last doctor tried to remove the sebaceous fluid with a needle, and it was rock-hard -- so nothing came out. He was concerned. Since then, my health coverage has changed for the worse, and I am now worried because it is growing so fast.

Could it be a pilomatrixoma? The overlaying skin is red/purple, and the skin is tented over the nodule. I have another small hard lesion in my left shoulder (pea-sized), which feels similar but has not changed shape or size since I noticed it 15 years ago. My mother died of breast cancer a few years ago, and cancer runs deep in my family, so I am nervous.
