Concurrent endobronchial carcinoid tumor and sarcoidosis.

Sarcoidosis is an inflammatory disease of unknown cause which is characterized by the presence of noncaseating granulomas. The association of sarcoidosis with malignancy has been an issue and remains controversial. We herein report endobronchial carcinoid tumor in a patient with sarcoidosis diagnosed by nasal mucosal biopsy, excisional biopsy of cervical lymph nodes and mediastinal lymph node dissection.
