Random white hard bump on forearm.

[pivotraze]

I found a random hard white bump on my forearm... I'm kind of worried. It's a single bump.

I am 19 years old and I have many white hard bumps under the skin of my arm. It doesn't hurt but it is slightly visible and much more visible when you press on it. I started to get these bumps about two-three years ago. I just noticed these bumps spread to my butt as well. When I squeeze my skin in some areas, white puss comes out of it. I also get scabs in my hair (since I was little, I always had a habit of picking at the scabs in my hair). And, since one year ago, I started seeing stuff on my right boob. I first had a black hard pimple like thing growing, but the stuff inside finally came out so it disappeared. However, now I get small/thin black pricks that pop up occasionally. I try to squeeze it out and eventually it comes out. I don't know if all of these relates, but I also have acne prone/dry (combination) skin. I am very scared that I have skin cancer. I will be seeing a dermatologist soon but if anyone knows what may be causing all these problems please let me know!

Hello,
This bump can be due to a cyst, actinic keratosis (small rough or scaly areas of skin due to damage from sun exposure), keratoacanthoma(rapidly growing skin cancer usually appearing as a volcano-like bump on the sun-exposed skin of middle-aged and elderly individuals), sebaceous hyperplasia or some malignancy. Since the bump is painless, hence I suggest you to get an examination done from a dermatologist as soon as possible.

It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing
