Thymic Carcinoma Associated with Pinealoma and Terminating with Peroxidase-negative Acute Myeloid Leukemia

Abstract

Thymoma is associated with a wide variety of syndromes. However, an association with peroxidase-negative acute myeloid leukemia and pinealoma, although feasible due to the marked influence of this tumor on the lymphoid system, has not been described previously. A patient with thymic carcinoma and pinealoma who developed peroxidase-negative acute myeloid leukemia as a late event is presented in this report. © 1992, The Japanese Society of Internal Medicine.
