Primary laryngeal candidiasis is rare in immunocompetent patients and is prone to confusion with early glottic carcinoma or leukemia. We experienced a case of 74-year-old man who has 3- month history of hoarseness. The pathologic diagnosis was laryngeal candidiasis. He was treated with antifungal agents for 4 weeks after vocal cord stripping under general anesthesia. After treatment, the patient had no candidiasis or discomfort with his voice. We report this case with a review of literature.

Nocardia species are aerobic, gram-positive pathogens found worldwide in soil. Nocardia is considered an opportunistic pathogen, and its infection mostly occurs in immunocompromised patients. We report a case of Nocardia farcinica induced mediastinitis and pneumonia that occurred in a 64-year-old male patient who had no significant medical history except for hypertension. He visited another hospital with a complaint of dyspnea and left chest wall pain. The symptoms arose 7 days ago without any trauma and they worsened. A mediastinal mass was found on computed tomography scan. After being transferred to our hospital for further evaluation, he was diagnosed with mediastinitis and pneumonia. As N. farcinica was found to be the causative organism by 16S rRNA sequencing, proper antibiotic therapy including trimethoprim/sulfamethoxazole was initiated immediately. After this, the patient improved and he was discharged. If an infection has a disseminating course, nocardiosis cannot be excluded even in immunocompetent patients. Once the diagnosis is established, prompt antibiotic therapy should be performed based on the severity.

Delftia acidovorans is a gram-negative motile rod found ubiquitously in soil and in water. Confirmed isolation from clinical infections is rare, and has been documented mostly in immunocompromised patients or those with indwelling catheters. A 53-year-old man was referred for the evaluation of a huge mass-like lesion found incidentally by chest X-ray. The lesion occupied more than half of the right lung and was diagnosed as a large loculated pleural effusion by CT scan. Bloody pus was drained through a percutaneous catheter, and D. acidovorans, identified by the Vitek GN card and confirmed by amplification of 16S ribosomal RNA and sequencing analysis, was isolated repeatedly from the drained pus. The patient was treated with imipenem/cilastatin to which the organism was sensitive. This is a rare report of chronic empyema associated with D. acidovorans in the respiratory system of an immunocompetent patient.

Klebsiella pneumoniae has emerged as a leading pathogen that causes pyogenic liver abscesses (PLAs) in Korea. K. pneumoniae liver abscess (KLA) is potentially life threatening, and the diagnosis is difficult. In developed countries, PLA is rarely observed in children and is frequently associated with disorders of granulocyte function and previous abdominal infection. We observed a case of KLA in a healthy 12-year-old boy. To our knowledge, this is the first reported case of KLA in an immunocompetent child without an underlying disease in Korea. The patient was treated with percutaneous catheter drainage and antibiotics. The catheter was placed in the intrahepatic abscess for 3 weeks and parenteral antibiotics (ceftriaxone and amikacin) were administered for 4 weeks, followed by oral antibiotics (cefixime) for 2 weeks. We reported this case to raise awareness of KLA in immunocompetent children among physicians, and to review the diagnosis, risk factors, potential complications, and appropriate treatment of KLA.

비장티푸스 살모넬라균에 의한 화농성 척추염은 면역이 정상인 소아청소년에서는 매우 드문 질환으로, 주로 면역저하자나 낫적혈구병과 같은 혈색소병을 가진 환자들이 이 질환의 위험군으로 알려져 있다. 본 증례는 발열과 우상복부 통증으로 내원한 정상 면역을 가진 건강한 13세 청소년에서 대변 배양 검사를 통하여 비장티푸스 살모넬라균을 확인하고, 지속된 발열에 대하여 추가 영상 검사를 통하여 화농성 척추염이 합병되었음을 확인한 증례로, 불명열의 검사로 배양 검사의 중요성을 인식하게 하고, 일반적이지 않은 살모넬라증의 임상경과를 보이는 경우에는 장외 국소감염의 합병증에 대하여 철저하게 조사하는 것이 중요함을 보여준다.

서론: 면역기능 정상인 환자에서 폐효모균증의 전산화단층촬영상(CT)의 소견을 알아보고자 하였다. 대상 및 방법: 조직학적으로 확진된 25명의 폐효모균증 황자를 대상으로 하였다. 13명은 남자였고 12명은 여자였으며, 평균연령은 53.7세 였다. 주 증상은 기침, 가래, 및 호흡곤란이었고, 12명의 환자에서는 증상이 없었다. 결과: 결절 혹은 다수결절(10명 40%)을 보이거나 분절 혹은 이분절성 폐경결(9명 36%)이 가장 흔한 소견이었다. 주 침범부위는 하엽(57%) 늑막하부(92%)였다. 폐경결 내부에 공기관지 음영(79%)을 보이며 용적감소를 보인 경우(71%)가 흔하였다. 간질비후 음영(44%) 및 공동형성(44%)도 자주 보였으나, 임파절 종대(8%) 및 늑막삼출(4%)은 드문 소견이었다. 결론: 폐 하엽 늑막하 부위에 다수의 결절 혹은 폐경결성 병변이 면역기능 정상인 환자에서 폐효모균증의 가장 흔한 소견이었다.

Cryptococcal pneumonia usually occurs in immunocompromised patients with malignancy, acquired immune deficiency syndrome, organ transplantations, immunosuppressive chemotherapies, catheter insertion, or dialysis. It can be diagnosed by gaining tissues in lung parenchyma or detecting antigen in blood or bronchoalveolar lavage fluid. Here we report an immunocompetent 32-year-old male patient with diabetes mellitus diagnosed with cryptococcal pneumonia after a ultrasound-guided percutaneous supraclavicular lymph node core needle biopsy. We treated him with fluconazole at 400 mg/day for 9 months according to the guideline. This is the first case that cryptococcal pneumonia was diagnosed from a percutaneous lymph node biopsy in South Korea.
