I have small freckle on my neck and it was itchy a few nights ago - That same night a lump appeared under it but went down the next morning and returned to normal  Now a few days later the lump is back (I had been checking it so maybe irritated it).  it has not gone down and I am worried it may be modular melanoma.
Hi, dear. I have gone through your question. I can understand your concern. You may have some reactive lymph node hyperplasia.  So it disappears itself and then reappear.  Don't worry about malignant melanoma.  Malignant melanoma don't have that characteristics. Just consult your doctor and take treatment accordingly. Hope I have answered your question, if you have doubt then I will be happy to answer. Thanks for using Chat Doctor. Wish you a very good health.
