Fig 1 Keratoacanthoma versus squamous cell carcinoma. A-C, Representative KA case. A, Hematoxylin-eosin stain; original magnification ×40. B, CD303/BDCA-2 immunostaining highlights the presence of numerous PDCs (+3) as single cells and clusters (original magnification: ×100). C, MxA immunostaining was diffuse and intense in the epithelium and inflammatory cells (original magnification; ×40). D-F, Representative case of squamous cell carcinoma. D, Hematoxylin-eosin stain; original magnification ×40. E, CD303/BDCA-2 immunostaining highlighted fewer PDCs (+1) mostly as single cells (original magnification ×100). F, MxA immunostaining was weak and patchy in the epithelium and inflammatory cells (original magnification ×40).
