Retrospective Evaluation of Synovial Chondromatosis with Histopathological and Clinical Features

Synovial chondromatosis (SC) is a rare, benign condition characterized by the formation of nodular cartilage within the synovium of joints, bursae, or tendon sheaths. The condition typically presents as loose body-like nodules, which often exhibit calcification and ossification. SC primarily affects adults and most commonly involves large joints. Histologically, it is defined by synovium-lined cartilaginous nodules displaying varying degrees of peripheral cellularity. Due to overlapping features, SC may be misdiagnosed as a chondroid malignancy, particularly in limited biopsy specimens.
