A very difficult case and obviously immunohistochemistry is required to come to a correct diagnosis. I think that the second image is the most helpful showing a tumor island surrounded by a dense lymphoid infiltrate. Well done to those who diagnosed a lymphoepithelioma-like carcinoma on the H/E.

Malignant tumor, My first impression is inflammatory MFH. The differential includes Metastatic carcinoma, anaplastic large cell lymphoma and melanoma.

I'm thinking the lymphoid infiltrate is reactive to an epitheloid malignancy.

My first thought is Rosai Dorfman disease, Immuno is required to confirm (S100, CD68)
