(a) Excisional biopsy of cervical lymph node showing sheets of large atypical lymphoid cells with frequent mitoses. (b) Positive CD30 staining of the lymphoma cells in the cervical lymph node biopsy. (c) Peripheral blood smear showing eosinophilia with partial degranulation and hypersegmentation. (d) Bone marrow core biopsy showing hypercellular marrow with markedly increased eosinophil precursors and eosinophils. (e) Bone marrow aspirate showing increased eosinophilic precursors, eosinophils with morphology similar to peripheral blood eosinophils and background dyserythropoiesis.
