Mycobacterium malmoense is a very rare cause of lung disease in South Korea. We reported the first case of lung disease caused by M. malmoense in an immunocompetent patient. The patient was successfully treated with a 14-month course of antibiotics.

Segniliparus species is a novel genus that is reported to be the new emerging respiratory pathogens. Here, we report a very rare case of S. rugosus pulmonary infection in an immunocompetent patient with non-cystic fibrosis. The organism was identified by 16S rRNA gene sequencing. The patient was successfully treated with antibiotics.

Cytomegalovirus (CMV) colitis, which is rare in an immunocompetent patient, was encountered in a 67-year-old man who was admitted due to persistent diarrhea. The first diagnostic tool was colonoscopy, which showed multiple ulcers from cecum to rectum. The secondary tool was CMV polymerase chain reaction, and CMV colitis was diagnosed. Intravenous ganciclovir therapy was administered, which resulted in improvement of diarrhea and ulcers throughout the colon were healed. Asymptomatic colon perforation was detected during diagnostic testing, which improved over the conventional treatment. CMV colitis is rare in immunocompetent patients, but it is essential for the differential diagnosis.

Varicella is a contagious infection in childhood disease typically affecting children aged 2-8 years and usually follows benign outcome. In the adult, clinical presentation is more severe and more commonly associated with complications. Varicella pneumonia, although rare, is a potentially life-threatening complication that should be suspected in any adult with varicella and respiratory symptoms. We report a case of varicella pneumonia in immunocompetent patient. The characteristic radiographic findings consisted of diffuse scattered coarse nodular infiltrations, less than 1cm sized, with ground glass opacity and consolidation in both lung fields. The patients was started on intravenous acyclovir. The chest radiograph performed 2 weeks later showed complete resolution of the pulmonary lesions.

대상포진 수막염은 대상포진 후 발생할 수 있는 신경학적 합병증으로 주로 면역 기능이 저하된 상태의 환자에게서 발생한다. 저자들은 면역 기능이 정상인 환아에서 피부 병변 없이, 수두 백신 접종을 한 경우 드물게 발생하는 대상포진 수막염 2례를 경험하였기에 보고하는 바이다.

The global number of Mycobacterium avium complex (MAC) pulmonary infection is increasing. Patients with preexisting lung disease or who are immunodeficient are at the greatest risk for developing MAC infection. Endobronchial lesions with MAC infection are rare in the immunocompetent host. However, there have been an increasing number of reports of an immunocompetent host being afflicted with various manifestations of MAC infection. We report a case of pulmonary and endobronchial MAC infection presenting as an acute pneumonia in a 59-year-old female without preexisting lung disease or immunodeficiency.

Usually fungal infections caused by opportunistic and pathogenic fungi had been an important cause of morbidity and mortality among immunocompromised patients. However clinical data and investigations for immunocompetent pathogenic fungal infections had been rare and neglected into clinical studies. Especially Cryptococcal brainstem abscess cases mimicking brain tumors were also much more rare. So we report this unusual case. This 47-year-old man presented with a history of progressively worsening headache and nausea for 1 month and several days of vomituritions before admission. Neurological and laboratory examinations performed demonstrated no abnormal findings. Previously he was healthy and did not have any significant medical illnesses. A CT and MRI scan revealed enhancing $1.8{\times}1.7{\times}2.0$ cm mass lesion in the left pons having central necrosis and peripheral edema compressing the fourth ventricle. And also positron emission tomogram scan demonstrated a hot uptake of fluoro-deoxy-glucose on the brainstem lesion without any evidences of systemic metastasis. Gross total mass resection was achieved with lateral suboccipital approach with neuronavigation system. Postoperatively he recovered without any neurological deficits. Pathologic report confirmed Cryptococcus neoformans and he was successively treated with antifungal medications. This is a previously unreported rare case of brainstem Cryptococcal abscess mimicking brain tumors in immunocompetent host without having any apparent typical meningeal symptoms and signs with resultant good neurosurgical recovery.

침습성 폐 아스페르길루스증은 주로 면역저하 환자에서 발생하는 것으로 알려져 있지만 드물게 면역저하가 없는 환자에서도 발생한다. 면역저하가 없는 환자에서 발병하는 경우, 초기에 진균에 의한 폐 감염을 의심하기가 어렵기 때문에 진단 및 치료가 늦어지고 나쁜 예후를 보일 수 있다. 저자들은 면역저하가 없는 29세 남성 환자에서 선천성 심장질환 수술 후 발생한 침습성 폐 아스페르길루스증의 사례가 있어 시간 경과에 따른 CT 소견과 함께 보고하고자 한다.

Invasive pulmonary aspergillosis (IPA) is rarely reported in patients who have normal immune function. Recently, IPA risk was reported in nonimmunocompromised hosts, such as patients with chronic obstructive pulmonary disease and critically ill patients in intensive care units. Moreover, influenza infection is also believed to be associated with IPA among immunocompetent patients. However, most reports on IPA with influenza A infection, including pandemic influenza H1N1, and IPA associated with influenza B infection were scarcely reported. Here, we report probable IPA with a fatal clinical course in an immunocompetent patient with influenza B infection. We demonstrate IPA as a possible complication in immunocompetent patients with influenza B infection. Early clinical suspicion of IPA and timely antifungal therapy are required for better outcomes in such cases.

Cyclospora cayetanensis is an agent of emerging infectious disease, and a recognized cause of diarrhea in some patients. Also, the flagellated protozoan, Giardia intestinalis, induces a diarrheal illness of the small intestine. Cases of cyclosporiasis are frequently missed, primarily due to the fact that the parasite can be quite difficult to detect in human fecal samples, despite an increasing amount of data regarding this parasite. On the other hand, G. intestinalis can be readily recognized via the microscopic visualization of its trophozoite or cyst forms in stained preparations or unstained wet mounts. In this report, we describe an uncommon case of co-infection with G. intestinalis and C. cayetanensis in an immunocompetent patient with prolonged diarrhea, living in a non-tropical region of Turkey.
