Insights
A 5-year-old boy developed hypertrophic osteoarthropathy due to lipoid pneumonia from ghee oil aspiration in infancy. This rare condition highlights a unique cause of chronic lung inflammation and joint pain in children.
Area of Science:
- Pediatrics
- Pulmonology
- Rheumatology
Background:
- Hypertrophic osteoarthropathy (HOA) is a rare condition characterized by digital clubbing, arthritis, and periostosis.
- While often associated with malignancy or chronic lung disease, pediatric HOA has diverse etiologies.
Observation:
- A 5-year-old Saudi boy presented with painful joints and digital clubbing.
- Radiological imaging confirmed hypertrophic osteoarthropathy.
- A history of ghee oil aspiration in infancy was noted, leading to chronic lung inflammation.
Findings:
- The underlying cause of HOA was determined to be lipoid pneumonia secondary to ghee oil aspiration.
- Lung biopsy confirmed the diagnosis of lipoid pneumonia.
- This case illustrates a unique etiology for pediatric HOA and lipoid pneumonia.
Implications:
- Highlights the importance of considering aspiration of foreign substances, like ghee oil, in the differential diagnosis of pediatric HOA.
- Emphasizes the long-term pulmonary and skeletal consequences of early-life aspiration events.
- Suggests a need for increased awareness among clinicians regarding non-respiratory causes of chronic lung inflammation and HOA in children.
Abstract:
A case of hypertrophic osteoarthropathy in a 5-year-old Saudi boy is presented. The child developed painful joints, was found to have clubbing of fingers and radiologically hypertrophic osteoarthropathy was demonstrated. The underlying cause of the condition was ingestion of animal fat in infancy, with a history of ghee oil aspiration which caused a chronic lung inflammation, lipoid pneumonia, proven by lung biopsy.
