Schwannoma arising in mediastinal lymph node diagnosed by endobronchial ultrasound

We report a rare case of schwannoma arising in mediastinal lymph node diagnosed by endobronchial ultrasound. Schwannoma is a peripheral nerve sheath tumour that largely originates from the posterior mediastinum. Schwannoma arising in mediastinal lymph node is extremely rare. A 53 ‐year‐old female was referred to our hospital for the evaluation of enlarged mediastinal lymph node. Computed tomography scan revealed a non‐enhancing soft tissue mass at Rt. paratracheal area. Endobronchial ultrasound showed a well‐defined round‐shaped lymph node and transbronchial needle aspiration was performed from this lymph node. Pathologic findings revealed spindle cells with strong S100 positivity. Complete surgical excision was done. We report a rare case of schwannoma arising in mediastinal lymph node diagnosed by endobronchial ultrasound.
