It is postulated that they originate from bone marrow stem cells. Accumulating evidence has established the existence of immunoglobulin gene and T-cell receptor gene rearrangements in these tumors. Cases of transdifferentiation across lineages from follicular lymphoma to histiocytic\/dendritic cell tumors have also been reported. Herein, we report 2 adult males with histiocytic neoplasms coexisting with B-cell lymphoma. Laser capture microdissection and capillary electrophoresis polymerase chain reaction analysis revealed comparable immunoglobulin gene rearrangement in both patients. In one case, chronic lymphocytic leukemia\/small lymphocytic lymphoma (CLL\/SLL), Langerhans cell sarcoma, and histiocytic sarcoma coexisted in the lymph nodes. 11q22 deletion often present in CLL\/SLL and expression of the BRAF V600E gene was detected in all the 3 components. In the other case, there diffuse large B-cell lymphoma and histiocytic sarcoma coexisted in the spleen. Forty-seven mutated genes commonly found in B-cell lymphoma were detected by next-generation sequencing. In the same line, DTX1, IRF8, KMT2D, MAP2K1, and TET2 genes were found to have similar mutation sites. The results of this study will contribute in providing new ideas for targeted treatment of these diseases.<\/jats:p>","DOI":"10.1177\/10668969211013402","type":"journal-article","created":{"date-parts":[[2021,5,3]],"date-time":"2021-05-03T12:21:56Z","timestamp":1620044516000},"page":"906-914","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":3,"title":["A Pedigree Analysis and Clonal Correlations of the Coexistence of  B-Cell Lymphoma and Histiocytic\/Dendritic Cell Tumor"],"prefix":"10.1177","volume":"29","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0557-3951","authenticated-orcid":false,"given":"Fei","family":"Cheng","sequence":"first","affiliation":[{"name":"The First Affiliated Hospital, School of Medicine, Zhejiang University, Hangzhou, Zhejiang, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fang","family":"Yu","sequence":"additional","affiliation":[{"name":"The First Affiliated Hospital, School of Medicine, Zhejiang University, Hangzhou, Zhejiang, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiaoxi","family":"Wang","sequence":"additional","affiliation":[{"name":"The First Affiliated Hospital, School of Medicine, Zhejiang University, Hangzhou, Zhejiang, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ke","family":"Huang","sequence":"additional","affiliation":[{"name":"The First Affiliated Hospital, School of Medicine, Zhejiang University, Hangzhou, Zhejiang, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hongsheng","family":"Lu","sequence":"additional","affiliation":[{"name":"Taizhou Central Hospital, Taizhou, Zhejiang, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhaoming","family":"Wang","sequence":"additional","affiliation":[{"name":"The First Affiliated Hospital, School of Medicine, Zhejiang University, Hangzhou, Zhejiang, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2021,5,3]]},"reference":[{"key":"bibr1-10668969211013402","volume-title":"Histiocytic and Dendritic Cell Neoplasms.
