Cutaneous gamma/delta T-cell lymphoma.

ABSTRACT

Only 40 cases of primary cutaneous gamma/delta T-cell lymphoma (GD-TCL) have been described. GD-TCL was included as a provisional entity in the WHO-EORTC classification of cutaneous lymphomas in 2005. GD-TCL often failed to respond to polychemotherapy and radiation therapy and have a poor prognosis with a mean survival of only 15 months. We present a patient treated with surgery, immunomodulatory therapy, and polychemotherapy. He then received hematopoietic stem cell transplantation and has been in complete remission since. Allogeneic stem cell transplantation appears to be a promising therapeutic option for aggressive and generally fatal lymphomas like GD-TCL.
