A 40 year old female presents with mediastinal hilar lymphadenopathy and she has recently noticed slight weight loss and a cough. Staging shows no other evidence of disease. A trucut biopsy reveals a lymphoma showing large cells with mirror image nuclei, lymphocytes, plasma cells and eosinophils. The following phenotype is seen; CD20 positive, CD3 negative, CLA positive, and CD15 positive

A 55 year old male presents with a history of chronic dyspepsia and with recent weight loss.
