Erosive papillomatosis of the nipple

This is a nice case of erosive papillomatosis of the nipple. The papillary structures fill almost the entire picture, and you can see the epithial erosion at the left hand side. Unfortunately I have no images of immunohistology yet.

The image was taken with a Nikon DN100 camera on a Nikon Optiphot 2 Microscope at 4x.
