CD3+, CD56+, CD4-, CD8-, CD20-, CD30- Peripheral T-Cell Non-Hodgkin's Lymphoma: A Rare Case Report.

Cutaneous T-cell lymphoma (CTCL) commonly presents as mycosis fungoides or Sezary syndrome, both having CD4 positivity. A subset of CTCL which lacks CD4 surface marker is classified as cutaneous γ and δ-T-cell lymphoma (CGD-TCL). Because of its rarity and inability to study large number of patients, the impact of immunophenotype on the clinical outcome of primary CTCL in patients is limited. We report a case of primary CGD-TCL in a 71-year-old male because of this rarity and to emphasize its aggressive nature.
