title: Sarcoid reactions scattered in the tumor-bearing lung parenchyma and regional lymph nodes associated with pulmonary carcinoid.
abstract: A 77-year-old woman was admitted to our hospital because of a mass lesion in the left lung. The tumor was pulmonary carcinoid associated with sarcoid reactions in the regional lymph nodes and scattered in the resected lung parenchyma. Pulmonary carcinoid with sarcoid reactions is extremely rare. This appears to be the first case report in which tumor-related sarcoid reactions were studded within the tumor-existing lung parenchyma and confirmed not to be within the uninvolved right lung.
