Melanoma Throat Question About Melanoma?

Question about melanoma? - melanoma throat

It is a small town near a canal at the back of the neck. I can not say if it is dark red or black. I have a history of melanoma, but I also have the flu now (my cultures and blood tests on Monday - the flu). The flu, it can lead to a place like this? If they malignant melanoma, that blood tests have been identified?
I'm crazy. Please give me some good news (if it is true, of course).
Thank you.
