An 11-year-old child presented to the emergency department in 2005 with episodes of pain in his right clavicle. No history of trauma was noted and he was systemically well with no clinical signs of acute inflammation. He was extensively investigated and a diagnosis of fibrous dysplasia of the right clavicle was reached on histology. He developed periodic relapses of pain in the clavicle. He has been followed up since 2005, his most recent follow-up being in November 2011. The clinical dilemma of fibrous dysplasia versus chronic osteomyelitis is illustrated by highlighting this case.
