Familial cutaneous mycosis fungoides: successful treatment with a combination of gemcitabine and alemtuzumab.

We report a familial cutaneous T-cell lymphoma in father and son. After different treatment modalities without lasting responses, the son was treated with gemcitabine as single agent and due to insufficient effect with alemtuzumab monotherapy. Only after the two drugs had been combined did we observe a remarkable response of the skin lesions and disappearance of enlarged lymph nodes. The combined treatment with gemcitabine and alemtuzumab was well tolerated, and no increased toxicity was noted. The combination of these two active agents may provide an additional option in the treatment of cutaneous T-cell lymphoma.
