cell population is homogeneous (i.e., >70% of the cells
resemble one another) or heterogeneous. If the population
VetBooks.ir is homogeneous, it is either a normal node (i.e., the cells are
normal lymphocytes) or it is neoplastic (lymphoma or
metastasis); if it is heterogeneous, it is either reactive, inflam-
matory, or early neoplastic.
