要約 目的:急速に進行し,角膜穿孔に至ったPaecilomyces属による角膜真菌症の症例の報告。症例:78歳男性が4日前からの右眼充血で受診した。8年前から兎眼性角膜症で加療中であった。所見と経過:矯正視力は右手動弁,左0.9で,右眼に毛様充血と角膜中央部の下方に羽毛状混濁を伴う角膜潰瘍と前房蓄膿があった。潰瘍部の擦過物から糸状菌が検出され,培養でPaecilomyces lilacinusと同定された。フルコナゾールの点眼と静注と1%ピマリシン眼軟膏投与が奏効せず,ボリコナゾールの内服を行ったが,第18病日に角膜が穿孔した。結膜被覆術を行い,ボリコナゾール点眼を開始した。その後角膜膿瘍は縮小した。結論:Paecilomyces属による角膜真菌症は予後不良なことがあり,早期診断と治療が重要である。
Abstract. Purpose:To report a case of keratomycosis with corneal perforation caused by Paecilomyces species. Case:A 78-year-old male presented with hyperemia since 4 days before. He had been treated for lagophthalmos during the foregoing 8 years. Findings:His corrected visual acuity was hand motion right and 0.9 left. The right eye showed ciliary injection, hypopyon, and corneal ulcer in the lower quadrant. Filamentous fungus was present in the corneal scrapings. It was identified as Paecilomyces lilacinus by culture. The lesion failed to respond to topical and systemic fluconazole with topical pimaricin followed by systemic voriconazole. The cornea perforated on day 18 of disease. The lesion subsided after covering by conjunctiva and topical voriconazole. Conclusion:This case illustrates that keratomycosis by Paecilomyces species may run a fulminant course. Early diagnosis and treatment are advocated.
