Adenoma bronquioloalveolar asociado a bronquiolitis obliterante y leishmaniasis pulmonar en el sida / Bronchioloalveolar adenoma associated with bronchiolitis obliterans and leishmaniasis with lung involvement in acquired immunodeficiency syndrome

RESUMEN

La leishmaniasis visceral no es inusual en pacientes con síndrome de inmunodeficiencia adquirida (sida), pero su afectación pulmonar es infrecuente. La leishmaniasis pulmonar a menudo se presenta como neumonitis intersticial. Describimos un caso en el cual el hallazgo de amastigotes en la biopsia transbronquial permitió el diagnóstico de leishmaniasis pulmonar. Sin embargo, los hallazgos radiológicos y del lavado broncoalveolar eran compatibles con una bronquiolitis obliterante que podría deberse al virus del sida. Además, la biopsia transbronquial permitió diagnosticar un adenoma bronquioloalveolar con la presencia radiológica de múltiples nódulos

ABSTRACT

Visceral leishmaniasis is not unusual in patients with acquired immunodeficiency syndrome (AIDS), but lung infiltration is uncommon. Leishmaniasis involving the lung often manifests as interstitial pneumonitis. We report a case in which the discovery of amastigotes in the transbronchial biopsy led to a diagnosis of leishmaniasis. However, the findings from x-rays and study of the bronchoalveolar lavage fluid were consistent with bronchiolitis obliterans, possibly caused by the AIDS virus. In addition, the transbronchial biopsy findings were consistent with a diagnosis of bronchioloalveolar adenoma with radiographic evidence of multiple nodules
