Synovial chondromatosis is a rare, benign, proliferative cartilaginous lesion arising from the synovial tissue, tenosynovium, or bursal lining. We describe the case of a patient who initially presented with multiple axillary masses. Breast ultrasound (US) was requested due to the concern of a breast tumor with axillary lymph node metastases. US study was helpful and provided adequate information to suggest the diagnosis.

Synovial chondromatosis (SC) is a locally aggressive neoplasm consisting of multiple hyaline cartilaginous nodules. This neoplasm typically manifests as multiple intra-articular calcified or uncalcified nodules, whereas the extraarticular form is particularly rare. We herein present a case of solitary extraarticular SC arising in the hand and correlate the imaging findings with pathologic findings.

Background: Synovial chondromatosis is a rare benign condition characterized by the formation of cartilaginous nodules within the synovium of joints, bursae, or tendon sheaths. While nonsurgical management exists, surgical intervention is often necessary. This systematic review aims to evaluate surgical options for managing synovial chondromatosis of the knee and compare recurrence rates following each procedure.

To analyze the short-and medium-term clinical outcomes of Mako robotic-assisted posterior-lateral approach in complex primary total hip arthroplasty (THA). A retrospective case series analysis was conducted on 29 patients with complex hip conditions who underwent Mako robotic-assisted posterior-lateral approach at Department of Orthopaedics, the Second Affiliated Hospital of Zhejiang University School of Medicine from November 2020 to December 2024. The patient cohort included 14 cases of developmental dysplasia of the hip, 8 cases of ankylosed hip, 3 cases of traumatic hip arthritis, 3 cases of sequelae of purulent hip arthritis, and 1 case of synovial chondromatosis.

Primary synovial chondromatosis of the hip is a rare pathology characterized by metaplastic changes in the synovium, leading to the formation of cartilage nodules and, eventually, free intra-articular bodies. Early manifestations, such as pain, stiffness, and limited mobility, require timely differential diagnostic process through imaging techniques, with magnetic resonance imaging being the gold standard diagnostic method, complemented by histopathological analysis. Considering the rarity of the condition, the diagnostic suspicion is linked to the expertise of the professional and the referral to specialized centers/professionals.
