Lack of pulmonary involvement leads to a 3 years delay of diagnosis in a childhood sarcoidosis case with arthritis, ocular symptoms, and bilateral parotid swelling

Key Clinical Message This paper presents a rare sarcoidosis case in a child of 12 years of age presented with arthritis, bilateral parotid enlargement and ocular, but unfortunately the diagnosis has been missed due to lack of pulmonary involvement. Abstract Diagnosis of sarcoidosis is by exclusion, and sometimes, it can be challenging. This paper presents a rare sarcoidosis case in a child of 12 years of age presented with bilateral parotid enlargement. The signs of musculoskeletal and ocular involvement were present before the parotid enlargement, and the parotid swelling persisted for 3 years; but unfortunately the definite diagnosis has been missed by the previous healthcare professionals most probably due to the rarity of the situation, especially lack of pulmonary involvement. Therefore, cooperation between different healthcare specialties is important for an effective diagnosis and management. Despite its rarity, sarcoidosis should always be present in the list of differential diagnosis when encountering multisystem entities like arthritis, ocular symptoms and parotid swelling.
