Scurvy mimicking as systemic lupus erythematosus

Scurvy is a disease caused by chronic vitamin C deficiency. The greater prevalence was found in the paediatric population with neurodevelopmental disorders such as autism spectrum disorders due to their restricted dietary intake. Our case reported a child with autism who presented with arthralgia and anaemia. Systemic lupus erythematosus was the first diagnostic impression, resulting in over investigation and delayed diagnosis of vitamin C deficiency. After the child was treated with ascorbic acid, the child's symptoms resolved. This case highlighted the importance of developmental and nutritional history taking in the paediatric population. Furthermore, parents and physicians should be concerned about nutritional status, especially in children with restrictive dietary intake.
