I can see Reed Sternberg cells in the last image so I will go for Hodgkin's lymphoma.

Don't know but epithelioid haemangioendothelioma and plexiform fibrohistiocytic tumour were my thoughts.

My impression is plexiform fibrohistiocytic tumor. Images show well-circumscribed nodules composed of plump histiocytic cells, some of them with dark wrinkle nuclei, embedded in a fibrous background. Age and site are also typical of this entity.

This neoplasm is composed of nodules of oval and round cells with moderate to abundant pale eosinophilic cytoplasm and uniform vesicular nuclei without mitotic figures or significant atypia. A fibrous capsule circunscribes the lesion and separates the neoplastic nodules. Lymphocytes and plasma cells are seen inside and around the tumor, mostly around it. Red blood cells are present too. These findings are typical of a angiomatoid fibrous histocytoma, solid variant. Location and age are also typical.

Yes thanks Romualdo for correcting us today and Thanks to Hafeez for sharing this case with us. I have only one example in my slide collection and have never seen a case in routine sign-out but it is certainly one that can appear in exams.
