Background: Burkitt lymphoma rarely presents in head and neck (H&N) in Western countries.
Aims/objectives: We aimed to characterise clinicopathological features of H&N Burkitt lymphoma in Denmark representing a non-endemic region.
Material And Methods: Clinical records were reviewed for a nationwide cohort of patients diagnosed with H&N Burkitt lymphoma in Denmark between 1980 and 2018. The diagnosis was histologically validated.
Results: Thirty-four patients with H&N Burkitt lymphoma (highest incidence in age group 0-9 years, male-to-female ratio 4.7:1) were included. Thirty-three lymphomas (97%) were extranodal. The tumour was visible at the clinical examination in 81% ( = 22) of the cases. The palatine tonsils were the most frequent location ( = 13, 38%) and 52% ( = 17) of the patients were diagnosed in advanced stage. Lymphoma was the tentative clinical diagnosis in 23% of the cases. The 5-year overall- and disease-specific survival was 78% and 81%, respectively.
Conclusions: Due to the rarity of Burkitt lymphoma of the H&N, there is a high risk of clinical misdiagnosis. Our findings suggest which symptoms and clinical presentations to be aware of in the diagnostics work up that could lead to the diagnosis of Burkitt lymphoma.

Comprehensive genetic analysis of tumors with exome or whole genome sequencing has enabled the identification of the genes that are recurrently mutated in cancer. This has stimulated a series of exciting advances over the past 15 years, guiding us to new molecular biomarkers and therapeutic targets among the common mature B-cell neoplasms. In particular, diffuse large B-cell lymphoma (DLBCL), follicular lymphoma (FL) and Burkitt lymphoma (BL) have each been the subject of considerable attention in this field.

Burkitt lymphoma (BL) is an aggressive non-Hodgkin lymphoma (NHL), subdivided into endemic, sporadic, and immunodeficiency-associated forms. While jaw lesions are common in endemic BL, they are infrequent in sporadic cases, only rarely constituting the first manifestation of the disease. The aim of this study is to present a rare pediatric case of sporadic BL first manifesting as gingival swellings and tooth hypermobility and provide a review of all the published sporadic BL case reports as the first sign of disease.

Background: To investigate the trends in Burkitt lymphoma incidence, mortality, and disability-adjusted life-years, considering sex and age, from 1990 to 2021, with a 20-year forecast.
Method: Data regarding Burkitt lymphoma were extracted from the Global Burden of Disease study for the year 2021.
Results: Globally, there were 19,072 incident cases of Burkitt lymphoma in 2021.
MicroRNA Expression in High-Grade B-Cell Lymphoma With 11q Aberration.

Institute of Human Genetics, Ulm University and Ulm University Medical Center, Ulm, Germany.
Mature aggressive B-cell lymphomas, such as Burkitt lymphoma (BL) and Diffuse large B-cell lymphoma (DLBCL), show variations in microRNA (miRNA) expression. The entity of High-grade B-cell lymphoma with 11q aberration (HGBCL-11q) shares several biological features with both BL and DLBCL but data on its miRNA expression profile are yet scarce. Hence, this study aims to analyze the potential differences in miRNA expression of HGBCL-11q compared to BL and DLBCL.

Background: Post-transplant lymphoproliferative disease (PTLD) is a significant complication that can arise following solid organ transplantation or hematopoietic stem cell transplantation. It encompasses a spectrum of lymphoproliferative lesions, ranging from benign reactive hyperplasia to malignant tumors, and is among the most severe complications following liver transplantation in children. It is essential for clinicians to gain a comprehensive understanding of the prevention, clinical manifestations, early diagnosis, and treatment strategies for PTLD in order to reduce mortality rates.
