Summary

Sarcoidosis is a multisystem disorder characterized by the development of non-caseating granulomas. Two distinct forms of sarcoidosis occur in paediatric patients. School-aged children and adolescents can develop classic sarcoidosis with manifestations similar to the disease in adults, including frequent hilar lymphadenopathy, pulmonary involvement and a wide variety of cutaneous findings. The latter can include both lesions characterized histologically by non-caseating granulomas, most often manifesting as red–brown papules and plaques that favour the face, and reactive lesions such as erythema nodosum. In contrast, infants and preschool-aged children typically present with a triad of arthritis, uveitis and papular granulomatous dermatitis that has been referred to as early-onset sarcoidosis (EOS). Recent studies have demonstrated that EOS and Blau syndrome (juvenile systemic granulomatosis or familial/paediatric granulomatous arthritis) represent a single disease entity caused by heterozygous mutations in the NOD2 (nucleotide-binding oligomerization domain 2) gene.
