  * Measurable disease defined by at least one single node or tumor lesion \> 1.5 cm.
  * Life expectancy of ≥ 90 days (3 months).
  * Patients must be eligible and willing to undergo excisional biopsies of tumor sites with a lymph node of minimum 1 cm at baseline and after 21 days of treatment
  * Females of childbearing potential (FCBP)† must have two negative serum or urine pregnancy tests with a sensitivity of at least 25 mIU/mL before starting lenalidomide - the first test must be performed within 10-14 days before starting lenalidomide treatment and the second test must be performed within 24 hours before starting lenalidomide
  * FCBP must either commit to continued abstinence from heterosexual intercourse or begin two methods of birth control, at least 4 weeks before she starts taking lenalidomide.
