title: Flare-up of squamous cell carcinoma of the skin following fludarabine therapy for chronic lymphocytic leukemia.
abstract: We present a 72-year-old patient with chronic lymphocytic leukemia (CLL). About a year following therapy with chlorambucil and prednisone, he suffered from anemia, thrombocytopenia and organomegaly. The patient received fludarabine with a favorable response. Concomitantly with the clinical improvement of the CLL there was a remarkable flare-up of scalp squamous cell carcinoma (SCC) lesions, initially noted 4 years previously. The lesions were multiple and grew rapidly. Fludarabine depresses the T lymphocyte population, cells that play a pivotal role in the regression of the SCC. We suggest, that the flare-up and exacerbation of the SCC lesions of the patient were triggered by the fludarabine therapy.
