The lymphoma cells are monoclonal, medium-sized, and have round nuclei with small nucleoli. They also exhibit high proliferation and apoptosis. Burkitt Lymphoma is categorized by specific chromosomal translocations (t(2:8) or t(8:22)). It is more common in men, with facial bones being the most affected site in the endemic form and the intestine in the nonendemic form. If left untreated, Burkitt Lymphoma can be aggressive and fatal, but it is curable.Rate this question:
