title: Malignant thymoma associated with peripheral T-cell lymphocytosis.
abstract: Three cases of peripheral T-cell lymphocytosis associated with thymoma are described. Each patient had a malignant, predominantly lymphocytic thymoma with resolution of lymphocytosis upon treatment of the epithelial neoplasm. These findings suggest that lymphocytosis complicating thymoma is a paraneoplastic phenomenon and is not part of the neoplastic process.
