[Primary] gastric lymphomas. are defined as lymphomas originating from the stomach and contiguous lymph nodes. Lymphomas at this site are considered primary if the main bulk of disease is located in the stomach. The majority of
gastric lymphomas are high-grade B-cell lymphomas, some of which have developed through progression from low-grade lymphomas of mucosa associated lymphoid tissue (MALT). The lowgrade lesions are almost exclusively B-cell MALT lymphomas.
Gene. Part of the body’s code for making new cells and controlling the growth and repair of the cells.
Germ cell tumour. Tumours derived from totipotent cells. In adults most often found in the testicle and ovary; in fetuses, babies, and young children most often found on the body midline, particularly at the tip of the tailbone; in horses most often found at the poll (base of the skull).
Giovanni Morgagni; of Padua was the first (in 1761) to perform autopsies to relate the patient's illness to their pathologic findings postmortem. Cancer could now be detected, albeit after death.
Grading. This term refers to the evaluation of microscopic features of a tumour that allows the pathologist to assign the tumor "a grade"; the grade of a tumour is important because it allows us to predict how aggressive a tumour will be
