title: Sarcoid reaction in primary tumor of bronchogenic large cell carcinoma accompanied with massive necrosis.
abstract: A 49-year-old woman consulted our hospital for evaluation of a tumor with cavitation in the S6 segment of the right lung. She was given a diagnosis of pulmonary tuberculoma because percutaneous needle aspiration cytology revealed epithelioid cells with a background of necrosis. However, a diagnosis of large cell carcinoma with central necrosis (p-T2NOM0) was established by thoracoscopic lung biopsy six months later. Pathological findings of surgical resection specimens showed that epithelioid cell granulomas adjacent to the neoplasm had a sarcoid reaction and the necrosis was related to the rapidly growing tumor because there was no clinical evidence of systemic sarcoidosis and pulmonary mycobacterial or fungal infection. This is the first report in which sarcoid reactions were recognized in a primary large cell carcinoma.
