Popis: Abstract Schwannomas are classified as neurogenic tumors and are the most frequent nerve sheath tumors in the paravertebral mediastinum. Recently, the addition of endobronchial ultrasound‐guided intranodal forceps biopsy (EBUS‐IFB) using standard‐sized biopsy forceps (SBFs) to endobronchial ultrasound‐guided transbronchial needle aspiration (EBUS‐TBNA) for metastatic lymph nodes in lung cancer patients reportedly improved the quality and quantity of the obtained specimens without significant complications. However, reports on the usefulness of this technique for benign diseases remain scarce. Here we report a case of schwannoma in the middle mediastinum, which was diagnosed by EBUS‐IFB using SBFs, despite inadequate specimens obtained via EBUS‐TBNA. An 80‐year‐old woman presented with dyspnea and a 5‐cm sized middle mediastinal tumor. EBUS‐TBNA and EBUS‐IFB using SBFs were performed for histological diagnosis. No complications were associated with the bronchoscopy procedure, and schwannoma was solely diagnosed using the EBUS‐IFB specimens. EBUS‐IFB using SBFs is potentially useful for diagnosing benign diseases, including schwannomas, which are often difficult to diagnose with EBUS‐TBNA.
