They also have an extra X chromosome that is a result of nondisjunction during meiosis (1). This common genetic disorder occurs in between 1:400 and 1:1000 of male births (1). We report here three patients with Klinefelter's syndrome who presented with a nonseminomatous tumor of the mediastinum. These observations lend support to the suggestion the dysgenetic germ cell tissue in Klinefelter's syndrome patients has an increased malignant potential (2).A 23-year-old patient (Case 1) had had gynecomastia for 5 years.
