Images of the month: Demonstrative oral mucosal sarcoidosis in a patient with pulmonary disease.

Sarcoidosis is a multisystem granulomatous disease that preferentially affects the lungs and intrathoracic lymph nodes. Oral involvement is quite rare and usually appears in patients with known systemic sarcoidosis but it may also be the initial finding of a systemic disease. Herein, we report a case of asyptomatic pulmonary sarcoidosis with cutaneous and oral involvement. Recognising oral sarcoidosis may be difficult but it is important not to miss an asymptomatic pulmonary sarcoidosis. Patients with oral lesions of sarcoidosis should be screened for systemic disease. © Royal College of Physicians 2020. All rights reserved.
