title: [Thoracic lymphoma in AIDS].
abstract: Over the last 4 years, we observed 122 patients with AIDS and 20 with AIDS-related lymphomas (ARL) in the chest. Eighteen of the latter were non-Hodgkin's forms, mostly high-grade and high-stage B-cell (Burkitt or Burkitt-like) types (16 cases.) This prevalence reflects the overall increase in neoplasms secondary to immunodepression, which is parallel to improved prevention and control of opportunistic infections. Of 20 ARLs, 5 (25%) presented thoracic lesions; in 4 of them the onset of the disease was localized in the chest. The incidence of such manifestations is higher than that reported in the literature. Moreover, radiological features are quite atypical relative to the "classical" signs of lymphoma in the general population, with predominant (60%) nodules or quickly-growing peripheral masses which may subsequently invade chest walls. Isolated nodal enlargement is also a possible finding, as well as pleural effusion. This pattern, though not pathognomonic, is highly suggestive--in HIV-positive patients--of ARL. In all the patients with pulmonary lymphoma CT demonstrated bilateral lesions--more than conventional X-rays--with morphologic and densitometric features which helped make the correct diagnosis. Moreover, CT was helpful in choosing the appropriate site for biopsy.
