Thymomas associated with pure red cell aplasia (PRCA) constituted only 3.3% of 122 thymomas treated in our department from 1963 to March, 1995. Four patients with this disease (2 men and 2 women, mean age: 58 years, range: 41 to 66 years old) are reported. Auto-antibodies were found in all 4 cases, increase of T cell in two, suppression of erythropoietin production in one, and antibody to EB virus in one. Operation was performed in all cases (two thymothymectomies, one extended thymothymectomy, and one thymomectomy), and 3 of 4 patients were in the progressive stage of Masaoka's classification (I, III, IVa, and IVb each). As for the pathological findings, mixed type was found in three cases and lymphocyte predominant type in one. Two patients died from radiation pneumonia. As for PRCA, postoperative therapy was effective (100%) in all patients.

UI MeSH Term Description Entries
D007166 Immunosuppressive Agents Agents that suppress immune function by one of several mechanisms of action. Classical cytotoxic immunosuppressants act by inhibiting DNA synthesis. Others may act through activation of T-CELLS or by inhibiting the activation of HELPER CELLS. While immunosuppression has been brought about in the past primarily to prevent rejection of transplanted organs, new applications involving mediation of the effects of INTERLEUKINS and other CYTOKINES are emerging.
