Bone marrow involvement: Atypical presentation of early-onset childhood sarcoidosis

Childhood sarcoidosis is a chronic multisystemic, non-caseating granulomatous disease of unknown etiology. Early-onset disease classically presents with a triad of skin rash, uveitis, and arthritis, but bone marrow involvement is rare. We report a 9-1/2- year old Indian female child who presented with bleeding manifestation, skin rash, uveitis, and arthritis. Bone marrow biopsy showed multiple non-necrotizing granulomas comprising epithelioid cells, mature lymphocytes, and multinucleated giant cells with few eosinophils in the background, with negative staining for acid-fast bacilli or fungi. She was treated successfully with oral prednisolone. This is the first report of an early-onset childhood sarcoidosis with bone marrow involvement from India.
