Autosomal recessive multiple pterygium syndrome, also known as Escobar syndrome, is characterized by multiple joint contractures (pterygia), short stature, and distinctive facial features such as down-slanting palpebral fissures. This rare genetic condition primarily affects the musculoskeletal system, often resulting in restricted joint mobility and spine curvature that typically present at birth. What are the primary clinical features of Escobar syndrome? The hallmark of Autosomal recessive multiple pterygium syndrome is the presence of webbing (pterygia) across joints, most commonly at the neck, armpits, and behind the knees.

The hallmark of Autosomal recessive multiple pterygium syndrome is the presence of webbing (pterygia) across joints, most commonly at the neck, armpits, and behind the knees. Beyond these physical signs, individuals with Escobar syndrome often experience:
The clinical expression of Escobar syndrome is highly variable. While some individuals may have mild joint limitations, others experience severe contractures that significantly impede mobility. Respiratory function can also be affected; because of the chest wall structure and potential spinal issues, some patients require proactive monitoring for restrictive lung disease. Daily quality of life is most often impacted by limited range of motion and the need for ongoing physical therapy to maintain functional independence.
Families managing Autosomal recessive multiple pterygium syndrome should seek urgent care if they notice signs of respiratory distress, such as rapid breathing or difficulty maintaining oxygen saturation, which can occur due to chest wall rigidity. Additionally, any sudden neurological changes or signs of spinal cord compression—such as new weakness or sensory changes—require immediate evaluation by a specialist.
While Autosomal recessive multiple pterygium syndrome is a congenital disorder, the secondary effects of joint contractures may progress during childhood growth spurts. Consistent orthopedic monitoring is essential to manage scoliosis and joint health, as early intervention can mitigate long-term complications.
