Burkitt lymphoma

Left panel: Lymph node touch inprint from a patient with Burkitt lymphoma shows multiple small noncleaved cells with a thin rim of basophilic cytoplasm containing numerous vacuoles. The macrophage in the center (yellow arrow) contains abundant cellular debris (ie, tingible body macrophage). Right panel: Bone marrow from the same patient shows two small noncleaved cells with eccentric nuclei, a thin rim of basophilic cytoplasm, and vacuoles aggregated at one pole of the cell (red arrows).
