RATIONALE: Biological therapies, such as therapeutic autologous lymphocytes, may stimulate the immune system in different ways and stop tumor cells from growing. Drugs used in chemotherapy, such as cyclophosphamide, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Cyclophosphamide may also stimulate the immune system in different ways and stop tumor cells from growing. Aldesleukin may stimulate white blood cells to kill tumor cells. Giving therapeutic autologous lymphocytes together with cyclophosphamide and aldesleukin may be an effective treatment for melanoma.
