Lymphoma of the Thyroid, Head and Neck Thyroid Gland Nodular sclerosing type is most common. There are two types of lymphomas: Hodgkin lymphoma; Non-Hodgkin lymphoma; Lymphocytes are the main white blood cells found in the lymph, which is the fluid of the lymphatic system; just as blood is the fluid of the circulatory system.
