Orbital non-Hodgkin's lymphoma

Non-Hodgkins malignant lymphoma is a group of lymphomas with varying degrees of malignancy. It can be divided into more than 10 types according to cell morphology, differentiation and distribution, and their clinical manifestations are mostly similar. Non-Hodgkin's malignant lymphoma mostly occurs in lymph nodes throughout the body and in the liver and spleen, but it can also occur in lymph reticulum or non-lymphatic reticulum outside the lymph nodes. Extraadenolymphomas account for 17.5% of all lymphomas. Lack of lymphatic tissue in the orbit. Primary malignant lymphomas in the orbit are extra-adenolymphomas, which account for about 3% of extra-adrenal malignant lymphomas. Orbital malignant lymphoma has been classified into the category of mucosa-associated lymphoid tissue malignant lymphoma in recent years. From the perspective of histopathology, there are three basic types of non-Hodgkins lymphoma that invade the orbit: benign reactive lymphocytosis, atypical lymphocytosis, and malignant lymphoma. Because they are similar in clinical manifestations and diagnostic techniques. Therefore, it is considered to be the same type of tumor, the difference is the difference in nature.
