A 59-years-old man presented with a one-year history of a pain-less swelling of his second metacarpophalangeal (MCP) joint of his right hand. Plain X-rays and CT scan revealed a circonpherencial erosive periarticular tissular lesion of the second MCP joint. MRI confirmed a chondroïd signal and an intraarticular localization of the tissular process. Surgical procedure consisted in volar and dorsal excision of the chondromatosis. The patient was free of disease one year after surgery. Gross specimen analysis showed multiple bluish white cartilaginous nodules. Microscopic view showed multiple hyaline cartilaginous nodules beneath synovial lining. Mild atypia and hypercellularity with focal nuclear hyperchromasia was observed as well as rare binucleated cells without myxoid changes. Chondromatosis of small articulation is a rare entity. In this giant presentation, a degree of atypia is often observed in synovial chondromatosis and does not imply malignancy. Synovial involvement is important to look for, as it is almost pathognomonic of the disease and exclude the differential diagnosis of soft tissue chondroma or chondrosarcoma.
