Epigenetic modifications are important early events during carcinogenesis. In particular, hypermethylation of CpG islands in the promoter region of tumor suppressor genes is a well-known mechanism of gene silencing that contributes to cancer development and progression. Tissue factor pathway inhibitor 2 (TFPI-2) is a tumor suppressor involved in invasiveness inhibition. Although TFPI-2 transcri...

Secondary pancreatic involvement can be seen up to 30% of advance staged non-Hodgkin’s lymphoma cases, but primary lymphomas constitute only 1% extranodal lymphomas. Furthermore, 0.2% the space-occupying lesions are lymphomas, which usually present as a mass in head pancreas with nonspecific symptoms.
