Abstract

BACKGROUND Double-hit lymphomas (DHL) belong to a category of very aggressive lymphomas characterized by MYC translocation and either BCL2, or less commonly, BCL6 translocations. Those with BCL6 translocations have a predilection for rare extranodal sites such as the gastrointestinal tract, nasopharynx, and tonsils. Involvement of the skull and adnexal structures is rare. Here we report a case of a young female with both skull and adnexal involvement. CASE REPORT A 20-year-old female who presented with hypercalcemia was found to have adnexal, skull, and jaw masses. Workup revealed a stage IV high grade B-cell lymphoma (HGBL) with MYC and BCL6 rearrangements. She was subsequently treated with R-EPOCH and attained complete remission 9 months after her initial presentation. To the best of our knowledge, our patient represents the first reported case of skull and adnexal involvement in HGBL with MYC and BCL6 rearrangement. CONCLUSIONS Rare extranodal presentations of HGBL with MYC and BCL6 rearrangement should be considered in the differential diagnosis of masses found in unusual sites such as the skull and adnexa. Due to their aggressive nature, early and prompt recognition of these lymphomas is essential for timely administration...Continue Reading

BCL-2 Family Proteins

BLC-2 family proteins are a group that share the same homologous BH domain. They play many different roles including pro-survival signals, mitochondria-mediated apoptosis and removal or damaged cells. They are often regulated by phosphorylation, affecting their catalytic activity. Here is the latest research on BCL-2 family proteins.

B-Cell Lymphoma

B-cell lymphomas include lymphomas that affect B cells. This subtype of cancer accounts for over 80% of non-Hodgkin lymphomas in the US. Here is the latest research.
