why not benign?
cellular atypia, frequent mitoses, tumorous necrosis,infiltrative tumor border, how can we make it a benign tumor?
Can you see the border of the tumor under such severe inflammatory background? none of these are necessary for a malignant tumor, all of these could exist in a benign disease, especially with such an inflammatory background.
just 4 this case. sorry if i have offended you.

I kind of agree with iamsailing. I was debating with myself about a benign process since the atypia is not dramatic and the background is quite inflammatory. If it is a benign or reactive process, those "neoplastic" cells would be best interpreted as histocytes? The high cellularity of those cells is pretty dramatic. If it is some kind of granulomatous process, there should be more cytoplasm. There does appear to have a few giant cells which may support a granulomatous lesion. In that case, it could be cat scratch disease or things along this line.
I would favor a malignant process. However, if the final answer is a benign process, I would not be too shocked:)
