Diffuse large B-cell lymphoma (DLBCL) accounts for approximately 30-40% of all non-Hodgkin lymphoma cases. Organs located DLBCL such as lymph node, stomach, gastrointestinal tract, or skin were reported. However, the adrenal gland DLBCL was not been well explored. We performed RNA sequencing of ten DLBCL samples from adrenal gland, integrated analyzed DLBCL RNA data from multiple organs, defined the new subtypes of adrenal gland DLBCL and explored their molecular signatures. The special expression pattern and microenvironment immunology scores of adrenal glands DLBCL were observed when compared with other organs. Natural killer T cells was predicted to significantly enrichment in adrenal gland DLBCL, canonical cancer pathways such as programmed death protein 1 signaling pathways, tumor necrosis factor signaling pathways and peptide antigen binding pathways were found to be correlated with adrenal gland DLBCL. Further analysis defined two distant adrenal gland DLBCL sub-type by RNA expression pattern. Our study revealed the special expression, defined the molecular subtype of adrenal gland DLBCL. These results expanded the organ related DLBCL data, provided the new knowledge of adrenal gland DLBCL expression profile.
