I recently had a shave biopsy and am a bit confused by the pathology report. The final diagnosis is atypical junctional melanocytic proliferation. The pathologist noted that immunoperoxidase analysis and multiple level sections were examined, and a markedly irritated dysplastic nevus (moderate to severe atypia) is favored. It then notes that it is Melan A positive. I am curios about the stain being positive, yet the final diagnosis being atypical melanocytic proliferation. Thank you for advising!
