A Case of Cutaneous Diffuse Large B-Cell Lymphoma and Concurrent Follicular Lymphoma In-Situ
نویسندگان
چکیده
Diffuse large B-cell lymphoma and follicular lymphoma are the most common non-Hodgkin lymphomas seen in adults. Follicular lymphomas are derived from germinal centers of lymphatic tissue and are composed of centrocytes and centroblasts arranged into secondary lymphoid follicles with a germinal center. Follicular lymphomas can transform into diffuse large B-cell lymphoma. Follicular lymphoma in situ has been identified as a risk factor for several B-cell neoplasms, including diffuse large B-cell lymphoma. We report a case of a 62 year old man with diffuse large B-cell lymphoma on his scalp, germinal center phenotype, who was incidentally found to have a nodal follicular lymphoma in situ on his chest wall. This case highlights the clinical implications of in situ follicular lymphoma.
