T-cell lymphoma

A malignant proliferation of T cells arising in the skin, diagnosed by detecting rearrangement of the T-cell receptor's β chain; TCLs are often 'driven' by EBV and other viral infections; 90% of all Pts with TCL have extracutaneous involvement when diagnosed. See Mycosis fungoides.
