RESUMEN
Alveolar hemorrhage in mixed cryoglobulinemia associated with hepatitis C virus infection. A 61 year-old woman with type II mixed cryoglobulinemia associated to hepatitis C virus infection has suffered alveolar hemorrhage with multiple pulmonary infiltrates, purpura, glomerulonephritis and polyneuropathy. The respiratory and kidney findings resolved with prednisone, but glomerulonephritis reappeared when interferon-alpha treatment was started and prednisone was reduced. This is the third case of alveolar hemorrhage and glomerulonephritis associated with mixed cryoglobulinemia reported in the literature. The lung involvement in mixed cryoglobulinemia is reviewed. The clinic manifestations (asthma, pleural effusion, hemoptysis or pulmonary fibrosis) are uncommon, but the lung involvement is very frequent if roentgenographic signs and necropsy findings are assessed.

Gastric tuberculosis is a rare entity that often coincides with pulmonary involvement at the time of diagnosis. Many cases reported in developed countries are in immunodepressed patients, particularly those with HIV infection. We report the case of a 43-year-old man who presented with weight loss of 14 kg, persistent vomiting and bilateral pulmonary nodes measuring 1.5 to 3 cm in diameter. An ulcerous, hypertrophic gastric lesion was observed by oral digestive endoscopy, such that the clinical, radiologic and endoscopic profile initially suggested gastric neoplasia with bilateral pulmonary metastasis. Examination of the gastric biopsy and of the bronchial aspirate revealed the presence of acid-alcohol resistant bacilli; a culture in Löwenstein-Jenssen medium was positive for Mycobacterium tuberculosis. The patient responded satisfactorily to short-term specific treatment with three drugs.
