Two cases of localized B-cell lymphoma in the acquired immunodeficiency syndrome.

We report 2 cases of localized B-cell non-Hodgkin lymphoma occurring on the face in AIDS patients. The tumors were limited to the skin and bone, without other involvement. They were characterized by an aggressive local behavior that caused infectious and compressive complications and resulted in fatal outcome. Knowledge of the possibility that lymphoma may remain localized in AIDS patients should prompt clinicians to perform a biopsy as soon as possible, regardless of the CD4 count. Indeed, early diagnosis might increase the efficacity of treatment and might avoid disastrous local complications.
