      A bit about myself I'm a 19 year old asian male, with chronic uticaria, lentigo spots, and obese. Not sure if that is relevant to diagnosis.

      Diagnosis: Right Anterior Proximal Thigh

      Lentiginous compound melanocytic nevus with mild to moderate atypia and partial regression; please see comment. (D48.5)

      Specimen Site: Right Anterior Proximal Thigh

      Gross Description: Pigmented 6 x 9 mm fragment – outer edges inked: trisected

      Microscopic Description: 

      In this apparent shave specimen, there is a compound melanocytic proliferation. Junctional melanocytes are arranged as nests and as single cell with a lentiginous growth pattern. Melanocytes with nevocellular features are present within the dermis. In some areas more prominent inflammatory fibrosis is present, consistent with an element of partial regression. Cytologic and architectural atypia is observed, being graded as mild to moderate.

      Comment: 

      This histology correlates with an atypical nevus variant. The melanocytic process closely approaches, but does not appear to involve the lateral edges. The base is uninvolved in these sample sections.

       

      My doctor said it was a dysplastic nevus, but the part about regression worries me. Any thoughts?

          Why does that worry you?  Regression can happen in benign moles.  You have a mild to moderately atypical lesion.  The odds that the regressed part is something different isn't really part of the equation.  Since melanoma grows from the top down, you'd see melanoma at the top if that was what the lesion was.  You have clean margins.  Not sure there is anything more you need to do except watch the scar area for any pigment regrowth.  And watch your other moles for change or new and different.
