Epidemiology and clinical manifestations of cutaneous T-cell lymphoma.

Cutaneous T-cell lymphoma (CTCL) encompasses a constellation of diseases of malignant clonal T lymphocytes that present initially in the skin. Within this disease spectrum, mycosis fungoides, and the Sézary syndrome are best known. Progress in the understanding of the T-cell malignancies now places other clinical entities within this disease classification. The authors review the epidemiology and clinical manifestations of CTCL.
