Primary hepatic anaplastic large-cell lymphoma of T-cell phenotype in acquired immunodeficiency syndrome: a report of an autopsy case and review of the literature.
Anaplastic large-cell lymphomas (ALCL) were first described by Stein et al. in 1985 as large-cell neoplasms with a pleomorphic appearance, subtotal effacement of the lymph node structure, and expression of the lymphoid activation antigen CD-30 (Ki-l). Since their first description, these tumors have been documented in a variety of extranodal sites. We report a primary hepatic anaplastic large-cell lymphoma in a patient with advanced AIDS, who presented with hepatic failure and multiple nodules in the liver. A complete autopsy showed discrete tumor nodules throughout the entire liver without gross or microscopic involvement of lymph nodes or any other organs by the neoplastic process. The tumor cells showed typical histological and immunohistochemical features of ALCL and were strongly immunoreactive with the T-cell markers CD-3 and UCHL-1. Only one previous case of primary hepatic ALCL has been reported in the literature, and this tumor occurred in an immunocompetent patient and was not immunoreactive for B- or T-cell markers. To our knowledge, this study represents the first reported case of primary hepatic anaplastic large-cell lymphoma of T-cell phenotype. Additionally, this is the first case of primary hepatic ALCL reported in an AIDS patient.
