Aggressive extranodal peripheral T-cell non-Hodgkin's lymphoma: A rare case report and review.

Non-Hodgkin's lymphoma (NHL) is primarily a disorder of lymph nodes, when limited primarily to extranodal sites it is referred to as primary extranodal lymphoma and accounts for 24-48% of all cases of NHL. The development of peripheral T-cell lymphoma is poorly understood and is thought to be associated with effector T cells involving chromosomal translocations. It has been suggested by few authors that the continued increased risk for NHL among highly active antiretroviral therapy (HAART)-treated human immunodeficiency virus (HIV)-infected persons may be a reflection of incomplete immune reconstitution and possibly a chronic state of B-cell hyperactivation. Here, we present one such rare case of extranodal NHL in a known HIV patient.
