Abstract
Reichel syndrome or primary synovial chondromatosis (PSC) is an uncommon benign metaplastic
condition that usually affects large joints. Though shoulder involvement was scarce,
there are only a few cases in the pediatric population. A 14- year-old boy was admitted
to the Pediatric Orthopedics department with right shoulder pain for 14 months. Imaging
revealed multiple loose bodies distributed throughout the glenohumeral joint. Upon
the arthroscopic approach, we remove all cartilaginous nodules within the glenohumeral
space and abarticular tendon. Histopathologic examination confirmed the diagnosis
of primary synovial chondromatosis. At follow-up, the patient remains free of symptoms,
and shoulder radiographs showed no recurrence of calcification. The present case illustrates
the clinical patterns, imaging features, histological findings, and therapeutic management
of shoulder primary synovial chondromatosis in a pediatric patient.
