Pyknodysostosis: A case report of an 8-year-old male with a rare genetic disorder

Introduction and importance: Pyknodysostosis is a rare genetic disorder characterized by skeletal and craniofacial abnormalities. It is an autosomal recessive disorder caused by mutations in the gene encoding cathepsin K. Pyknodysostosis is associated with short stature, brittle bones, and distinctive facial features. Case presentation: This case report presents the clinical manifestations, diagnostic challenges, and management strategies of an 8-year-old male with pyknodysostosis, an extremely rare genetic disorder characterized by skeletal and craniofacial abnormalities. The patient's clinical presentation, radiographic findings, genetic testing results, and treatment approach are discussed. Additionally, the importance of genetic counseling and multidisciplinary care in managing this condition is emphasized. Clinical discussion: A multidisciplinary approach involving orthopedics, genetics, dentistry, and psychological support is crucial for managing patients with pyknodysostosis. Regular follow-up visits, careful monitoring of fractures, and appropriate interventions can improve the patient's quality of life and reduce complications. Conclusion: The importance of early recognition, genetic testing, and multidisciplinary care is emphasized for effective treatment and support. Further research is needed to enhance our understanding of this rare genetic disorder and develop targeted therapies.
