Abstract

Bronchopulmonary infections caused by trichomonads have been reported principally in patients with pre-existing pulmonary diseases, such as bronchial carcinoma, lung abscess, or bronchiectasis. Pulmonary trichomoniasis is most often caused by Trichomonas tenax, which is usually regarded as a harmless commensal organism of the human mouth. However, pulmonary infection may rarely be caused by other trichomonas species, including Trichomonas vaginalis from the genitourinary tract and Trichomonas hominis from the intestines. Because of the rarity of trichomonas pulmonary infection, and because of its close association with underlying lung and systemic disease, pulmonary trichomoniasis is considered an opportunistic infection. We recently treated a case of pulmonary trichomoniasis occurring in a young, healthy male without obvious underlying pulmonary or systemic illness. To our knowledge, there has been only one reported case of pulmonary trichomoniasis in Korea, and there have been only two reported cases of pulmonary trichomoniasis occurring in normal lung worldwide.

폐트리코모나스증은 인체에 기생하는 3가지 종류의 편모충류(구강편모충, 질편모충, 장세포편모충)에 의해 유발되는 매우 드문 기회 감염성 질환으로 대부분 만성 폐질환이나 화농성 또는 괴사성 폐질환을 앓고 있는 환자 및 면역저하를 동반하는 전신질환을 앓고 있는 사람에서 흡입 또는 직접 전파에 의해 발생된다. 일반적으로 질편모충을 제외한 구강 및 장세포편모충은 병원성이 없는 것으로 고려되어 치료가 필요하지 않지만, 정상적으로 분포하지 않는 장기에서 기회감염을 일으키는 경우 적극적인 치료가 고려되어야 한다. 저자들은 폐 및 전신적인 기저 질환이 없는 무증상의 건강한 남성에서 우연히 발견된 흉부 방사선 검사상 이상 소견에 대해 폐트리코모나스증을 진단하여 항균제 치료로 호전된 드문 예를 경험하여 보고하는 바이다.
