Figure 4. Clinical course. Steroid administration resulted in mild reduction of mediastinal mass-like lesion. However, as the steroid dose was tapered off, there were 4 relapses with re-enlargement of the mediastinal mass-like lesion. At 13 months after the disease onset, the hilar and mediastinal lymph nodes gradually became enlarged. Eighteen months after the disease onset, a routine blood test detected abnormal cells incidentally on a hemogram. Dex – dexamethasone; M – month; mPSL – methylprednisolone; PB – peripheral blood; Rec – recurrence.
