Sarcoidosis with Pulmonary Parenchymal Involvement and Co-existent Endobronchial Carcinoid

Sarcoidosis and sarcoid reactions are associated with various malignancies such as Hodgkin lymphoma (HL), acute myelod leukemia (AML), renal cell carcinoma (RCC), etc. Carcinoid tumors of colon, lung and kidneys co-existing with sarcoidosis are documented. Thyroid disorders were also found along with sarcoidosis and carcinoid tumors. Most of the case reports on concurrent lung carcinoid and sarcoidosis had non-metastatic carcinoid tumor and sarcoidosis without pulmonary parenchymal involvement. This is a case report of endobronchial typical carcinoid tumor with metastasis to regional lymph nodes co-existing with sarcoidosis having stage II disease. This case study concludes that there may be an association of endobronchial carcinoid tumor and sarcoidosis.
