A 31-year-old male presented to clinic with 2 months of aching shoulder pain without inciting injury or recent illness. Radiographs and MRI were obtained and the leading diagnosis was synovial chondromatosis (SC) of the acromioclavicular joint. He was treated with surgical resection. This case represents a rare location for SC, a disease defined by chondral tissue growth within the synovium most commonly affecting the knee and hip. We present this case report and consolidate information published in previous reports to provide guidance and discuss management for a rare and difficult location of this disease.
