Hodgkin lymphoma with a Reed-Sternberg cell
In the center of the photomicrograph is a classic Reed-Sternberg cell,a binucleate cell with large “owl’s eyes” eosinophilic nucleoli.
Hodgkin lymphoma, nodular sclerosis variant
Note the nodules of lymphocytes and other hematopoietic cells divided by broad fibrous septae.
Hodgkin lymphoma, mixed cellularity variant
Note the Reed-Sternberg cell (arrowhead). The other cell types in this image are reactive (only the Reed-Sternberg cell is neoplastic) and include neutrophils, lymphocytes, and, prominently in this image,eosinophils.
Spleen, non-Hodgkin lymphoma. This spleen exhibits uniform multicentric involvement of the white pulp by a malignant lymphoma. These changes contribute to generalized splenomegaly.
This lymph node exhibits the characteristic low power features of follicular lymphoma, tightly packed lymphoid follicles of approximately equal size.
Follicular lymphoma involves this hilar lymph node. The black material (arrow) represents normal lymphoid parenchyma with anthracotic pigment displacedto one side by the expanding tan lymphomatous process.
Diffuse large B-cell lymphoma
The photomicrograph shows a sheet of monotonous large neoplastic cells with prominent nucleoli.
This photomicrograph illustrates the characteristic low power features of Burkitt lymphoma, a sheet of neoplastic cells interspersed with punctate clearings (“starry sky pattern”). The punctate clearings are macrophages engulfing cellular debris. Burkitt lymphoma is an aggressive rapidly growingneoplasm with abundant cellular turnover, hence the presence of the macrophages
