Non-Hodgkin's lymphoma associated with the acquired immune deficiency syndrome: a report of five cases.

We report a series of five HIV positive patients with histologically proven non-Hodgkin's lymphoma. The paper illustrates the difficulties experienced in both the clinical diagnosis and its histological confirmation. In this series we have confirmed the predominance of aggressive histological variants and the high frequency of extra-nodal involvement. The prognosis despite treatment was poor; only one patient entered complete remission and the mean survival was only 4.3 months.
