title: Cutaneous squamous cell carcinoma in patients with chronic lymphocytic leukemia.
abstract: Patients with chronic lymphocytic leukemia are at heightened risk for the development of cutaneous malignancies, especially squamous cell carcinoma. These tumors portend a worse prognosis than is typically seen in immunocompetent patients. Patients with chronic lymphocytic leukemia who develop squamous cell carcinoma are more likely to develop multiple tumors, recurrences after treatment, and regional or distant spread of their tumor. Evaluation of the literature substantiates the ominous nature of squamous cell carcinoma in patients with underlying lymphocytic malignancies.
