Nonhepatosplenic γδ T-cell lymphomas represent a spectrum of aggressive cytotoxic T-cell lymphomas with a mainly extranodal presentation.

In conclusion, the lack of TCRβ expression does not always predict a γδ T-cell derivation since TCR silent cases may be found. The recognition of γδ TCL presenting in extranodal sites other than skin and liver/spleen expands the clinical spectrum of these tumors. However, non- HSTL γδ TCL do not appear to represent a single entity. The relationship of these tumors to either HSTL or PCGD-TCL requires further study.
