Note: it's a little redder than normal in the pic because I basically have to scratch the area a bit to find the bump.  
  
Had this bump for 5ish years with no changes. The dimensions of the bump seem to be 3 mm width and 4 mm length, less than 1mm in height, and doesn't seem to have any depth. When I try pushing down on it, there's no pain and I just feel the muscle underneath it. There's multiple healthy hairs growing out the cyst, in the middle and near the edges.

Doesn't feel hard, but not exactly soft either. Kinda feels like there's extra skin on top of the area. And there's no feeling on the bump it's self. It still keeps it form when pressed, and moves with skin when you push the cyst a little bit. The whole bump moves as one object when pressing down. No feeling of dryness or crustiness. No bleeding, oozing, or indent. No sign of irritation around the bump normally and doesn't irritate easily. It doesn't hurt when pushing my nail into it. It seems attached to the surface level of the skin. The bump is blanchable is turns fully white when pressed on. Tried putting a flashlight into the skin next to it, and it just looked like normal skin.

There's no irritation around skin next to the cyst, and the skin feels like normal skin. It seems like the transition from the normal is basically the cyst just shooting up and in a oval shape. There's no indentation in the cyst or around the edges.

The one time I did irritate it and it scabed and turned very red, it healed in about 5 days and there was no change in form. Also tried using rubbing alcohol on it and it gave no reaction.

My face and neck are very oily. The bump seems to get oily if I touch it too, no drainage. I smelled my finger afterwards and no order.

I've had a pilonidal cyst in my early 20s that was removed. I also have a oily face and scalp and still deal with pimples on my face and near the ears. My dad also had some keratosis build up on his head when he was younger.  


Is this a keratein plug or is it some kind of cyst?
