The patient is an 82 man who presented  for evaluation of a facial lesion.  That lesion was a basal cell carcinoma.  However a complete skin exam revealed a suspicious tumor on the right upper back. 

The patient has type III skin.  This "new" lesion on the back is an eight mm in diameter hypopigmented papule with an eccentrically placed  2 mm pigmented papule.

The patient is scheduled for an excisional biopsy of the back lesion.  What are your thoughts at this time?
