Most MCLs can be diagnosed based on morphological features, cyclin D1 expression, and IGH\/CCND1 rearrangement. However, in some atypical cases where conventional FISH studies fail to detect IGH\/CCND1 rearrangement or immunohistochemistry for cyclin D1 is negative, the diagnosis of the disease can be difficult. Hence, next-generation sequencing (NGS) may allow the identification of molecular alterations and assist in the diagnosis of atypical MCL. In this study, we reported a case of a patient diagnosed as asymptomatic MCL who presented with lymphadenopathy during the initial assessment. A lymph node biopsy was performed and the results revealed a high Ki67 index. However, initial diagnosis of aggressive MCL was difficult since the IGH\/CCND1 rearrangement result was negative. Ultimately, by the aid of NGS we identified a rare <jats:italic>CCND3<\/jats:italic> rearrangement in the patient, which lead to overexpression of cyclin D3, thereby facilitating the diagnosis of MCL.<\/jats:p>","DOI":"10.3389\/fonc.2023.1145376","type":"journal-article","created":{"date-parts":[[2023,3,29]],"date-time":"2023-03-29T06:12:48Z","timestamp":1680070368000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Case
