I am a 41 year old female. I had a mole that newly presented on the back of my knee. It was about 6mm and very very black. I had it biopsied and the results were: Spitz Nevus – Junctional. The report read orderly nests were present, large nuclei, and some pagetoid spread with many melanocytes present. It was recommended that I have a complete re-excision to remove it completely due to my age, rareness of this growth, and because atypical cells were present. I had the re-excision and I am awaiting the results. I am concerned because I have read about misdiagnosis being common in adult patients with spitz nevus. I have a family history of melanoma with an uncle diagnosed with Ocular Melanoma and a maternal first cousin diagnosed at the age of 24. Both family members were diagnosed stage IV. Should I have a second opinion? or is this pretty standard?
