TCRgamma gene rearrangement analysis in skin samples and peripheral blood of mycosis fungoides patients.

Abstract

TCR-gamma gene rearrangement analysis can be regarded as a useful adjunct to diagnosis of epidermotropic lymphoproliferative disorders. The presence of a dominant clone in both the skin and peripheral blood was more frequently detected in late stages and in patients with disease progression, confirming the usefulness of clonality detection by TCR-gamma gene rearrangement analysis in follow-up of patients with primary cutaneous T-cell lymphomas.
