Isolated primary hepatic lymphoma in a patient with acquired immunodeficiency syndrome.

Non-Hodgkin lymphoma (NHL) of the B-cell type is the second most common neoplasm in patients with human immunodeficiency virus (HIV) infection after Kaposi sarcoma (KS). The majority of cases of NHL in patients with acquired immunodeficiency syndrome (AIDS) involve extranodal sites; most frequently the gastrointestinal tract (GIT) and the central nervous system (CNS). Hepatic NHL in patients with AIDS was first described by Reichert et al in 1983 in an autopsy series. It usually presents with multiple large hepatic masses and involvement of other abdominal organs or lymph nodes. The authors present a case of primary hepatic NHL in a patient with AIDS, presenting with innumerable small intrahepatic masses without the involvement of any other organs.
