Histological examination of ovarian lymphoma. Hematoxylin and eosin-stained sections (original magnifications X20, X100 and X400) show a lymphoid proliferation of small B-cells with a widely monotonous growth pattern, suggestive for high-grade B-cell lymphoma. The round nuclei have finely clumped and dispersed chromatin with multiple basophilic medium size nucleoli, often located in paracentral side.
