Certainly, we could use lidocaine without epinephrine. The anesthetic effect doesn't last quite as long, but it will work. Even for regular excisions we can use lidocaine without epinephrine if need be.
Melan-A is a protein found in melanocytes (pigment producing cells) as well as a few other cell types (which aren't in the skin). It will be found in normal melanocytes that you'd see in completely normal moles and it will be found in most, but not all melanomas. Antibodies to Melan-A are used to identify melanocytes in pathology specimens-basically to help make sure that what they think are melanocytes really are melanocytes. Sometimes they may also be looking at whether the cells are losing Melan-A. So, whether the stain is + or - truly does not equate to whether or not its melanoma. It really is better to think of it as an additional tool that they can whip out and use if the diagnosis is not a slam dunk.We wish that when we sent in specimens we'd get a clear cut answer. Is this melanoma or not? Seems easy, right, sort of like asking is that a butterfly or a bird? Many times, though, its a lot more like asking, "Is that a Monarch or a Viceroy butterfly?" If you know your butterflies well, you can tell them apart. But nature's not perfect, so what if you had a freakishly ugly orange butterfly that's old, survived an encounter with a sparrow and has whatever the butterfly equivalent of buck teeth and bow-legs; and you had to figure out, "Is that a messed up Monarch or a messed up Viceroy butterfly?"When pathologists render a diagnosis, the pathologist is taking a lot of factors into account, such as the appearance of the cells; including their size, shape, what their nucleus looks like, what their cytoplasm looks like; as well as the way the cells are grouped in the skin-sort of like whether they are symmetric, asymmetric, crazy..... Then, they can also look at staining patterns with antibodies like Melan-A/Mart1, another one called HMB-45, and another one called MITF. There are even more tests beyond these that can be done when necessary.
There are no known natural remedies, cures, or prevention measures for lipomas. Their development is usually sporadic and unpredictable
Its probably as good as its going to get without doing something to it.Looking at your picture, it looks like you still have a very good shape to your nose. I can't tell for sure from the picture whether the scar is completely flat for not, but if it isn't there are lasers and other procedures that can make it flat.As for the redness, BBL/IPL or a vascular laser can wipe that out. When I see your nose, I do see a really good surgical result but also a really annoying amount of redness that I'd love to take a laser to because I'm very confident that I can make that red go away.
If you feel that you won't be happy with the scar unless you got it from a plastic surgeon, then you definitely should go that route.
