Malignant immunoblastic lymphoma with filopodia (so-called anemone or porcupine cell tumour).
The ultrastructure of a lymph node showed cells with cytoplasmic projections described by other authors as anemone cell tumour or porcupine cells. Histology and immunohistochemistry have shown that this tumour is a malignant B cell lymphoma, immunoblastic, with Kappa light chains. Our findings thus confirm recent studies suggesting that some of these tumours were malignant lymphomas.
