Background: Sarcoidosis is a granulomatous disease with unknown cause that can vary from an asymptomatic condition. ​Almost half of the patients with sarcoidosis have no symptoms. Case report: 8 year-old female, referred from Abha Hospital as a case of prolonged fever. The fever was low grade, lasted for months, mostly at night, and was associated with fatigue and no weight gain. Systemic review showed abdominal distension, history of knee pain, mouth ulcers and temporary rash on feet. Conclusion: Sarcoidosis is a disease that mostly affects the lung, but sometimes it is outside the lung, as in our cases. Doctors should pay attention to this so that the wrong diagnosis does not lead to complications or death of the patient.
