title: Diffuse large B-cell lymphoma with Homer-Wright rosettes, sinusoidal growth pattern, and CD30 expression: a possible overlap between microvillous lymphomas and sinusoidal CD30-positive large B-cell lymphomas.
abstract: Rosette formation is an unusual finding in malignant lymphomas. We herein report another case of a diffuse large B-cell lymphoma (DLBCL) with ultrastructural evidence of cellular projections, sinusoidal growth pattern, and strong CD30 expression. A literature review of the DLBCL cases showing all these features was also performed.
