ABSTRACT

As doenças pulmonares intersticiais (DPIs) são conceituadas como distúrbios que acometem o parênquima pulmonar - o endotélio cailar, os alvéolos, o epitélio alveolar e os espaços entreestas estruturas, bem como os tecidos perivasculares e linfáticos - , podendo ser classificadas segundo critérios histopatológicos, distinguindo-se dois grandes grupos: 1. das associadas à inflamação e fibrose; e 2. daquelas com reação granulomatosa predominante na área intersticial u vasculas. A linfangioliomiomatose (LAM) é uma rara DPI, idiópática, e com altas taxas de morbimortalidade, sendo caracterizada por uma multiplicação acelerada de células musculares lisas imaturas em qualquer estrutura pulmonar. No presente artigo apresentar-se-á uma revisão da literatura enfocando a etiopatogenia, a epidemiologia, o quadro clínico, o diagnóstico - procedimentos, critérios e diagnóstico diferencial - o tratamento e o prognóstico da LAM.


The interstitial pulmonary diseases (IPDs) are a range of disorders that affect the pulmonary parenchyma - the capillary endothelium, alveoli, alveolar epithelium and the spaces between thesestructures, as well as the perivascular and lymphatic tissues. The IPDs may be classified according to histopathologic criteria, and are divided into two large groups: 1. those associated with inflammation and fibrosis; and 2. those associated with granulomatous reactions predominantly in the interstitial or vascular area. Lymphangioleiomyomatosis (LAM) ia a rare, idiopathic IPD with high morbimortality rates, which is characterized by an accelerated multiplication of immature smooth muscle cellsin any pulmonary structure. In this article, we present a review of the literature onthe etiopathogenesis, epidemiology, clinical picture, diagnosis and differential diagnosos, treatment, and prognosis of this condition.
