Malignant thymomas are invasive and recur frequently, but noninvasive thymo
mas rarely do so. We report on a case of recurrent thymoma in a 50-year-old
white man, 32 years after total excision of a stage I thymoma. We stress t
he importance of long-term follow-up in all patients. (C) 1998 by The Socie
