Fig 1 A and B, The original excision (April 2012) yielded a predominantly well-differentiated cSCC with abundant keratin and an associated marked giant cell reaction. Minimal foci of moderate differentiation were present. Tumor closely abutted small cutaneous nerves multifocally. Retrospective S100 protein immunostain confirmed absence of perineural invasion at this time.

Fig 2 The subsequent recurrences (March 2015) were histologically similar. A, Obliterated nerve. B, The cutaneous components include the identical abundant keratin and the associated giant cell reaction.
