NCI Definition: An extranodal, mature T-cell non-Hodgkin lymphoma that originates from cytotoxic T-cells, usually of gamma/delta T-cell type. It is characterized by the presence of medium-size neoplastic lymphocytes infiltrating the hepatic sinusoids. A similar infiltrating pattern is also present in the spleen and bone marrow that are usually involved at the time of the diagnosis. [1]
