I suggest you start asking for copies of your pathology reports for your own files. Clark's Level IV isn't too specific. The Breslow depth – depth in millimeters is the most important prognostic factor. It's best to keep your own copies of these reports – create your own medical history file. Then you don't have to rely on doctors for this information. If you change doctors or a different specialist needs this information, you have it!
As for primary vs. metastasis – the pathology would have to determine that as well. But given the distance away and the size of the lesion, I still would lean towards a new primary as opposed to metastasis. Hang in there – even new lesions don't have to be melanoma.
