[Case of pulmonary pseudallescheriasis responding successfully to treatment with voriconazole].

A 27-year-old man was admitted with hemoptysis in October 2005. Chest radiograph and CT showed multiple nodules forming a large mass in the left upper lobe. We suspected pulmonary aspergillosis because we detected filamentous fungi made of chains of cells in the bronchial washing fluid. On October 6, therapy with micafungin was initiated. Despite this intervention, the patient's clinical status worsened. On Octorber 11, we suspected pulmonary pseudallescheriasis because we detected colonis resembling white down in Sabouraud agar, thus mica-fungin was discontinued due to the lack of response and we began treatment with voriconazole. The patient's clinical status subsequently improved. We performed a left upper lobectomy, because residual the shadows were recognized on chest CT. Here we report a rare case of pulmonary pseudallescheriasis successfully treated with voriconazole and left upper lobectomy.
