Pulmonary sclerosing pneumocytoma mimicking malignancy in endobronchial ultrasound‐guided transbronchial needle aspiration: A case report

Although Pulmonary sclerosing pneumocytoma (PSP) is generally considered to be a benign tumor, it represents a diagnostic challenge due to its controversial etiology and biologic behavior, the diversity of histopathohistological findings as well as the difficult differential diagnosis from poorly differentiated lung adenocarcinomas or carcinoids. EBUS‐TBNA alone cannot be accepted as the final definitive diagnostic approach for this tumor especially if the specimen is not sufficient.
