Endobronchial cryptococcosis without pulmonary parenchymal involvement caused by in an immunocompetent host.

is a yeast-like fungus. Pulmonary lesions caused by typically present as single or multiple nodules or infiltrative lesions in the lungs; however, endobronchial lesions are rare. A 40-year-old previously healthy Japanese man was referred to our hospital due to an abnormality detected on chest computed tomography.

Utility of contrast-enhanced magnetic resonance lymphangiography for yellow nail syndrome with lymphangiopathy: a case report.

Yellow nail syndrome (YNS) is a rare disorder characterized by the triad of yellow nails, lymphedema and chronic respiratory manifestations. Lymphatic abnormalities are a characteristic finding of YNS. Nevertheless, proof of lymphatic vessel abnormality by direct needle puncture for contrast agent injection is technically challenging because the lymphatic vessels in YNS are dysplastic.

Impact of chronic co-infection in pulmonary Mycobacterium avium complex disease after treatment initiation.

Background: The impact of co-infection with other pathogenic microorganisms after initiation of treatment for Mycobacterium avium complex pulmonary disease (MAC-PD) has not been clearly described. This study sought to clarify the clinical outcomes of co-infection with MAC after antimycobacterial therapy for MAC.

Methods: Co-infection status was defined as the detection of pathogenic microorganisms other than MAC in at least two consecutive sputum cultures 6-24 months after initiation of treatment.

Bronchial Brushing and Diagnosis of Pulmonary Nontuberculous Mycobacteria Infection.

Background: The optimal bronchoscopy procedure for diagnosis of pulmonary nontuberculous mycobacteria (NTM) infection is unclear.

Objective: This study investigated the usefulness of bronchial brushing in bronchoscopy for diagnosis of pulmonary NTM infection in patients with suspected NTM lung disease and nodular bronchiectasis on chest computed tomography (CT) images.

Methods: Bronchoscopy was prospectively performed for 69 patients with clinically suspected pulmonary NTM infection on chest CT from December 2017 through December 2019.
