Two patients were suspected of having extrinsic allergic alveolitis due to exposure to an agent in their home environment. On inspection of their houses, fungal decay was evident in the floorboards, and fungal spores were found deposited on many surfaces. The decay fungus was later identified as Leucogyrophana pinastri. Using an extract of the fruiting bodies and mycelium of this fungus, precipitating antibodies were identified in the sera of both patients. Based on the known exposure by the two patients to these small spores, the absence of a likely alternative allergen, the similarity between these two cases, and the positive precipitin test results, L. pinastri was considered to be the most likely cause of extrinsic allergic alveolitis in our cases.
两名患者疑似因在家中接触某种物质而患外源性过敏性肺泡炎。检查他们的房屋时，地板上明显有真菌腐烂迹象，且在许多表面发现有真菌孢子沉积。后来鉴定出腐烂真菌为松白卧孔菌。用这种真菌的子实体和菌丝体提取物，在两名患者的血清中均检测到沉淀抗体。基于两名患者已知接触这些小孢子的情况、不存在可能的其他过敏原、这两例病例的相似性以及阳性沉淀试验结果，松白卧孔菌被认为是我们病例中外源性过敏性肺泡炎最可能的病因。
