The Alphabetical Index should be consulted to determine which symptoms and signs are to be allocated here and which to other chapters. Enlarged lymph nodes should not be ignored. But all enlarged lymph nodes are not lymphoma. Enlarged lymph nodes are often the first sign of lymphoma, a cancer of lymph cells. These nodes were identified only at the mesenteric root in 32 patients (68), only in the mesenteric periphery in eight patients (17), and only in the right lower quadrant in five patients (11). Practically all categories in the chapter could be designated 'not otherwise specified', 'unknown etiology' or 'transient'. Infections, cancer, and many immune diseases can affect lymph cells and cause an enlargement of lymph nodes. The mean size of the largest nodes was 4.8 mm (range, 3-9 mm), and the mean size of the nodes found per patient was 3.6 mm (range, 3-6 mm). In general, categories in this chapter include the less well-defined conditions and symptoms that, without the necessary study of the case to establish a final diagnosis, point perhaps equally to two or more diseases or to two or more systems of the body. Signs and symptoms that point rather definitely to a given diagnosis have been assigned to a category in other chapters of the classification.This chapter includes symptoms, signs, abnormal results of clinical or other investigative procedures, and ill-defined conditions regarding which no diagnosis classifiable elsewhere is recorded.
