Hajdu-cheney syndrome with osteomyelitis of mandible, calcification of falx cerebri and palatal groove

Orofacial characteristics in a child with Hajdu-Cheney syndrome

Hajdu-Cheney syndrome (HCS) also known as Cranio-skeletal dysplasia is a rare genetic disorder of bone metabolism. It is mainly characterized by acro-osteolysis and generalized osteoporosis. The other distinctive features include a dysmorphic face, short stature, aplasia of facial sinuses, and persistent cranial sutures. Although the condition begins to manifest since birth, the characteristic features become more prominent with age. This syndrome is usually recognized by dentists due to these craniofacial abnormalities. This case report aims to highlight a case of 6-year-old girl HCS who presented with aberrant facial features, premature exfoliation of teeth, unusual mobility of teeth and atypical root resorption in primary dentition.

Hajdu Cheney Syndrome

Hajdu-Cheney Syndrome is a rare genetic disorder characterised by progressive focal bone destruction. It is known to be an autosomal dominant disorder but there have been reports of sporadic cases as well. Although the disease manifestation is found to begin from birth, it is most often not diagnosed until adolescence or adulthood. It could be due to the rarity of the condition and the variation of the disease manifestation at different age groups. We report a case of Hajdu-Cheney Syndrome in a 26-year-old male who presented with severe periodontitis and premature loss of teeth. The other characteristic features included craniofacial dysmorphism, abnormalities of the digits and dental anomalies. Patients with craniofacial dysmorphism along with dental abnormalities should be thoroughly examined for any underlying systemic disorder. A team of specialists may be able to diagnose this condition before the disease is advanced.
