The thin line between sarcoidosis and cancer: can we consider PET as an oncologic screening tool in radiologically stable and asymptomatic sarcoidosis?

Is controversy over whether granulomatous inflammation is a precursor to future malignancy or whether a particular patient is predisposed to develop granulomatous inflammation in the presence of a tumor antigen. Our case report highlights the importance of PET as a diagnostic tool to be performed during the follow-up of asymptomatic patients who have been radiologically stable for years, for oncological screening purposes, considering the risk of developing cancer in sarcoidosis.
