Abstract
A 71-year-old man with follicular lymphoma of the right inguinal lymph node was referred to our hospital owing to mediastinal lymph node enlargement (left #12). The patient had a history of cyclosporine (CYS-A) and steroid therapy for fibrotic hypersensitivity pneumonitis. Endobronchial ultrasound-transbronchial aspiration and endobronchial ultrasound-guided intranodal forceps biopsy (EBUS-IFB) were performed under conscious sedation using midazolam and fentanyl. Histological examination of the tissue obtained by EBUS-IFB soley revealed follicular lymphoma.
