Gene rearrangement of cutaneous T-cell lymphoma.
Gene Rearrangement is considered to be a helpful tool for diagnosis of cutaneous T-cell lymphoma. In this study five patients with clinical diagnosis of cutaneous T-cell lymphoma were reviewed for their clinical presentation, skin biopsies and surface marker phenotypes. Southern blot analysis of DNA extracted from their skins revealed that rearrangement of T-cell receptor beta chain (TCRB) genes happened in three patients but rearrangement of immunoglobulin heavy chain genes was absent. TCRB rearrangement could also detect lymphoma involvement of lymph nodes, peripheral blood and bone marrow in our patients. In these conditions, systemic therapy is suggested.
