Thymoma immunological and ultrastructural characterization

Abstract

A 69-year-old man with a mediastinal mass was found to have atypical lymphoid cells in peripheral blood and bone marrow. Light and electron microscopic studies showed that the mediastinal mass was a thymoma. B- and T-cell differentiation and PHA responsiveness in the tumor and peripheral blood were consistent with T-cells. After excision of the tumor and a course of radiotherapy the B/T ratio and PHA responsiveness in peripheral blood returned to normal while the atypical lymphocytes disappeared from circulation.
