Hepatosplenic T cell lymphoma causes

Etiology
The cell of origin for this disease is an immature cytotoxic T-cell clonally expressing the γδ T-cell receptor. This disease is seen more often in immunosuppressed solid organ transplant recipients, an association that has led to the hypothesis that long-term immune stimulation in the setting of immunosuppression is the causative agent.
