Abstract
Seven cases of relatively rare lymph node diseases were investigated by using ANAE and ATPase stains, in order to count the ratio of T and B cells. These diseases were consisted of 2 cases of T zone lymphoma, 1 case of hemangioma cavernosum, 3 cases of prolymphocytic leukemia and 1 case of Castleman's lymphoma. All materials used lymph node imprints. In T zone lymphomas there was seen a relative predominant T cell population, which showed as ANAE-droplet positive cells. In prolymphocytic leukemias and Castleman's lymphoma, B cell and plasma cell which reacted as ATPase-diffuse or ANAE-granular positive cells were estimated 70% or more. Various classifications of non-Hodgkin's lymphoma have been attempted by many investigators, but T zone lymphoma is not yet given a distinct entity, differing from other lymphomas. Moreover, prolymphocytic leukemia and Castleman's lymphoma are not clarified their cell origin, then recently discussed from many points of view because of their various histological changes case by case. Our report in this time showed that T cell was predominant in T zone lymphomas and B cell was a chief component in prolymphocytic leukemias and Castleman's lymphoma.
