Abstract: | As information on the clinical features and prognosis of thymoma complicated by pure red-cell aplasia is limited, follow-up data on thymoma patients who had a thymectomy between 1954 and 1999 were analyzed retrospectively. Six of 166 cases were complicated by pure red-cell aplasia. In 3 of these, the pure red-cell aplasia appeared after surgical intervention. Remission was observed in 2 patients who underwent extended thymectomy. The other 4 patients subsequently died from pure red-cell aplasia. The outcome in patients with pure red-cell aplasia was poorer than that in the entire group of patients with thymoma and in those with thymoma complicated by myasthenia gravis. The possible onset of pure red-cell aplasia after thymectomy should be kept in mind during follow-up. |
