title: Cylindroid lamella-particle complexes in lymphoma cells by northern pike (Esox lucius).
abstract: Cells of the malignant lymphoma of northern pike of Canada contained cylindrical structures with central cores of cytoplasmic elements and walls composed of lamellae in a spiral arrangement, separated by ribosome-like particles or by membranes. These cylindroids were similar, if not identical, to structures in the cells of certain human lymphomas and leukemias. In cross and longitudinal sections, the lamellae showed a pattern of light and dark bands resulting in an approximately 95 A-period that has not been described in the human cylindroids.
