Abstract
Sarcoidosis is a granulomatous disorder. Rarely, malignancy is accompanied by a granulomatous reaction. This retrospective study addressed whether cancer can masquerade as sarcoidosis. TriNetX identified 1029 newly diagnosed cases of sarcoidosis between October 2015 and September 2020, of whom 50 had a subsequent diagnosis of malignancy. In 36 cases, the malignancy was unrelated to sarcoidosis. In 7 cases, the diagnosis of sarcoidosis delayed the eventual cancer diagnosis by a range of 1 month to 2 years. In 7 cases, the subsequent diagnosis of cancer might have been related to the therapy for sarcoid. Cancer masquerading as sarcoidosis is very rare occurring in 7 (0.7%) of our 1029 cases. In no case was lung cancer masquerading as sarcoidosis. Searching for occult malignancy in patients with a known diagnosis of sarcoidosis is rarely indicated.
