Childhood sarcoidosis: diagnostic issues

摘要

Childhood sarcoidosis is a rare granulomatous disorder that affects several systems including the lungs, skin, eyes, and bones. On histopathology, non-caseating granuloma is the classic feature. We present a case of late childhood sarcoidosis of the skin, lungs, and bones demonstrating granulomas with fibrinoid necrosis, making distinction from tuberculosis difficult.
