title: Cutaneous gamma/delta T-cell lymphoma treated with radiation and denileukin diftitox.
abstract: Cutaneous gamma/delta T-cell lymphoma (CGD-TCL) is a rare and usually fatal lymphoma that is generally resistant to chemotherapy and radiation. It has recently been included as a provisional entity in the combined 2005 World Health Organization-European Organization for Research and Treatment of Cancer consensus classification. Subcutaneous panniculitic T-cell lymphomas with a gamma/delta T-cell receptor phenotype are now distinguished from the less aggressive alpha/beta panniculitic T-cell lymphoma. We describe a patient with deep ulcers initially diagnosed as pyoderma gangrenosum, which was reclassified as CGD-TCL. Local radiation followed by weekly infusions of denileukin diftitox put the patient into remission.
