Strange Gray Spot

I have a small discolored spot on my shoulder. It looks pale and gray. Whenever I touch, press, or scratch it, a horrible smell emerges. Sometimes this dry, sticky, ooze pours out(not like a liquid) almost like pinching out a blackhead. No amount of soap can clean it, I've tried acne medicine and it doesn't work. Should I be concerned, what is it?

Oh, and it popped out of the spot where I popped a pimple.

Just bumping this! I really want to know.

Anyone? Please?

Hello,
From the symptoms it sounds like a sebaceous cyst. A sebaceous cyst is a closed sac occurring just under the skin which contains a "pasty" or "cheesy" looking substance called keratin.They may occur anywhere on body but scalp, ears, back, face, and upper arm, are common sites for sebaceous cysts. Blocked sebaceous glands, swollen hair follicles and excessive testosterone production will cause such cysts.

Generally no treatment other than applying warm compresses is required but they become painful then it means they are infected, then surgical excision by traditional wide excision, minimal excision, and punch biopsy excision may be required.

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 dermatologist. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
