Abstract
Context: Primary extranodal diffuse large B-cell lymphomas of the thyroid (ptDLBCL) constitute a rare entity, which until now was not fully explored. Objective: Due to recently published data genetically linking ptDLBCL to a subset of thyroid carcinoma, we assessed the occurrence of oncogenic mutations and copy number alterations. Design: A high-resolution array-based comparative genomic hybridization approach was applied to quantify genomic aberrations in a study population of 21 ptDLBCL patients. In addition, we investigated the frequency of mutations involving the BRAF, NRAS, and MYD88 genes in correlation with immunohistochemical data. Results: Chromosomal gains were recurrently detected at 6p21.33-p21.31, 6p22.2, 12p13.31, 14q31.1, 14q32.33, 19p13.3, and 22q11.22; numeric losses were most frequently observed at 6p21.3-p21.31, 10q26.3, 19p13.3, 20q13.33, and 21q11.2. Aberrations affecting 6p22.2 and 14q32.33 as well as 22q11.22 differed slightly between germinal center B-cell (GCB) and non-GCB groups....
