Sarcoid-like pulmonary disorder in human immunodeficiency virus-infected patients receiving antiretroviral therapy.

We report two cases of HIV-infected patients who presented with diffuse interstitial micronodular lesions on chest X-ray after institution of protease inhibitor-containing highly active antiretroviral therapy (HAART). Granulomatous pulmonary disorder mimicking sarcoidosis was diagnosed on histopathological studies revealing noncaseating granuloma and bronchoalveolar lavage analysis showing an intense CD4(+) lymphocyte alveolitis. Causative agents such as infectious organisms and environmental compounds were excluded. The relationship between sarcoid-like reaction and immune reconstitution under HAART is discussed.

[Acute respiratory distress in a patient with sickle-cell anemia].

The acute chest syndrome is a frequent complications of sickle-cell disease characterized by chest pain, fever, and new infiltrate on chest x-ray image. Pathophysiologic factors appear to be multifactorial and better known. We report the case of a 28-year-old woman with homozygous sickle cell anemia who developed acute chest syndrome probably secondary to fat embolism.

AIDS-related primary pulmonary lymphoma.

We describe 12 cases of AIDS-related primary pulmonary lymphoma occurring between 1986 and 1996 in a large French cohort of HIV-infected patients. Diagnostic criteria were: (1) histologically proven lymphomatous pulmonary involvement; (2) absence of mediastinal and/or hilar adenopathy on chest radiography; (3) absence of extrathoracic lymphoma extension. All patients were severely immunodeficient at the time of diagnosis. All but one patient presented with B and/or nonspecific respiratory symptoms. Chest radiography showed one or more marginated nodule(s) or large mass. CT scan showed a cavitary lesion in five patients. No lymph node enlargement or specific pleural effusion was detected. Transthoracic needle biopsies were performed in 10 patients and avoided open-lung biopsy for the diagnosis of lymphoma in five patients. All but one of the primary pulmonary lymphoma were high-grade B-cell non-Hodgkin's lymphomas. Using antilatent membrane protein-1 antibodies and an Epstein-Barr-Virus-encoded RNA transcript-specific probe, latent EBV infection of tumor cells was demonstrated in every case. All but one of the patients received chemotherapy. The median survival time was 4 mo, and no patient was still alive at the cut-off date for this analysis. Progessive pulmonary lymphoma was the main cause of death, but infections were also frequent.

[Cystic opacity of the posterior mediastinum].

A patient with atypical clinical signs had a thoracic schwannoma in the left paravertebral gutter. Rigorous analysis of the standard x-rays, computed tomography examination and magnetic resonance imaging gave the diagnosis and guided surgical resection. The pathology report confirmed the imaging findings.
