I've had this hole along my jawline for about 4 years now. I think it's an open pore, but it's much larger than any I've ever seen before. When squeezed a small amount of white substance similar to the stuff that comes out behind a very deep blackhead comes out. I'm just wondering what it could be, if not a large pore, and what I should do about it. I'll attach a picture, I'm not sure how much help it will be, it's not very clear.
From the symptoms it looks like a sebaceous cyst. Blocked sebaceous glands, swollen hair follicles and excessive testosterone production will cause such cysts.
Generally no treatment 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 doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
