Summary:

      RATIONALE: Immunotoxins, such as RFT5-dgA immunotoxin (also called anti-CD25 immunotoxin
      IMTOX25), can find certain cancer cells and kill them without harming normal cells.

      PURPOSE: This phase II trial is studying the side effects of anti-CD25 immunotoxin IMTOX25
      and how well it works in treating patients with relapsed or refractory cutaneous T-cell
      non-Hodgkin lymphoma.
