The diagnosis of alveolar lipoproteinosis was established in a 46-year-old man's lung biopsy. The tissue was processed both for paraffin sections and electron microscopy. Morphology corresponded to the data in literature. Nevertheless, detailed clinical search and morphology failed to reveal causal factors. The case belonged to the group of alveolar proteinosis with uncertain etiopathogenesis.
一名46岁男性的肺活检确诊为肺泡蛋白沉积症。该组织进行了石蜡切片和电子显微镜检查。形态学与文献数据相符。然而，详细的临床检查和形态学检查均未发现病因。该病例属于病因发病机制不明的肺泡蛋白沉积症组。
