We report an immunohistochemical study of the distribution and number of interdigitating reticulum cells (IDC) and S-100 beta-positive small lymphocytes (S-100 beta + lymphocytes) in 53 thymomas and 11 thymic carcinomas. All 53 thymomas showed the presence of IDC in the tumor parenchyma. In most cases of predominantly lymphocytic and mixed-type thymoma, IDC clustered in areas, that corresponded to locations that had medullary differentiation and contained accumulated mature lymphocytes.
