Abstract

The Aspergillus species produces metabolic products that play a significant role in the destructive processes in the lung. We experienced a case of chronic necrotizing pulmonary aspergillosis caused by an Aspergillus niger infection, which contained numerous calcium oxalate crystals in the necrotic lung tissue. A 46-year-old man, who had a history of pulmonary tuberculosis, presented with high fever, intermittent hemoptysis and pulmonary infiltrations with a cavity indicated by the chest radiograph. Despite being treated with several antibiotics and anti-tuberculosis regimens, the high fever continued. The sputum cultures yielded A. niger repeatedly, and intravenous amphotericin B was then introduced. The pathological specimen obtained by a transbronchial lung biopsy revealed numerous calcium oxalate crystals in a background of acute inflammatory exudates with no identification of the organism. Intravenous amphotericin B was continued at a total dose of 1600 mg, and at that time he was afebrile, although the intermittent hemoptysis continued. On the $63^{rd}$ hospital day, a massive hemoptysis (about 800 mL) developed, which could not be controlled despite embolizing the left bronchial artery. He died of respiratory failure the next day. It is believed that the oxalic acid produced by A. niger was the main cause of the patient's pulmonary injury and the ensuing massive hemoptysis.

Aspergillus 종 특히 Aspergillus niger는 폐조직에 칼슘 옥살산 결정(oxalate crystal)을 침착시키면서 페손상을 초래하는 것으로 보고되고 있다. 저자들은 Aspergillus niger에 의해 생성된 옥살산염(oxalaic acid)에 의해 환자의 폐손상이 야기되고 그 결과 대량객혈이 발생한 것으로 추정되는 증례를 경험하였기에 보고하는 바이다. 과거에 식도암파 폐결핵으로 치료받은 적이 있는 46세 남자 환자가 고열과 간헐적 객혈, 그리고 흉부 방사선상 공동을 갖는 폐의 이상 음영을 주소로 내원하였다. 입원 후 항생제와 항결핵 치료를 병합하였지만 고열이 지속되었다. 객담 검사상 Aspergillus niger가 반복적으로 배양되어 정맥내 amphotencin B를 주입을 시작하였고, 이후 환자는 간헐적인 객혈은 지속되었으나 열은 소실되었다. 경기관지폐생검으로 얻은 조직에서 균은 동정되지 않았으나, 수많은 칼슘 옥살산 결정과 주위로 급성 염증성 삼출물이 관찰되었다. 환자는 입원 63일째 약 800ml 가량의 대량 객혈이 발생하였고, 기관지 동맥 색전술을 시행하였으나 출혈이 지속되었고 결국 호흡부전으로 사망하였다.
