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]

Hepatosplenic T-cell lymphomas most frequently harbor alterations in PTEN, POT1, and FBXW7 [2].

Most Commonly Altered Genes in Hepatosplenic T-Cell Lymphoma

PTEN Mutation, PTEN G127E, POT1 Mutation, POT1 H264N, and FBXW7 R479Q are the most common alterations in hepatosplenic T-cell lymphoma [2].
