“…The case of patient no. 31 has been reported previously by the authors as a case report of phase III synovial chondromatosis . Tissue from the lavage fluid consisted of many small islands surrounded by perichondrium, with partial calcification (Fig.…”

“…Crystalline materials are occasionally undetectable with panoramic radiographs, and ectopic cartilaginous components are also undetectable in many cases . It appears that early stage symptoms of some TMJ diseases are clinically similar to those of TMD and TMJ diseases in the early stage can be misdiagnosed with TMD . Detecting the crystalline components, monocyte lineage cells (macrophages or foreign body‐type giant cells) or cartilaginous components in joint lavage fluids by cell block tissue array method can be helpful for an earlier definitive diagnosis and to avoid invasive treatments, such as arthrotomy or synovectomy …”

“…Temporomandibular joint (TMJ) disorders (TMD) are diagnosed based on the patient's clinical findings and the results of image investigations; however, understanding of the inflammatory processes in TMJ is difficult. In addition, many TMJ disease types (such as crystalline arthritis, synovial chondromatosis, and TMD) share some principal symptoms, such as TMJ sounds and pain, lateral deviation, and difficulty in mouth opening. Therefore, TMJ diseases in the early stage can be misdiagnosed with TMD …”

“…Presence of monocyte lineage cells or multinucleated giant cells in inflamed tissue suggest the presence of calcium phosphate crystals, which cause crystalline arthritis . Furthermore, presence of osteoclasts suggests modeling or remodeling of the TMJ, and the presence of cartilaginous components suggests synovial chondromatosis …”

Temporomandibular joint (TMJ) disorders (TMD) are usually diagnosed based on the patient's clinical findings and the results of image investigations; however, understanding of the inflammatory process in TMJ is difficult. In addition, many of the TMJ disease types share common principal symptoms. Therefore, TMJ diseases in the early stage can be misdiagnosed with TMD. It is hypothesized that cytopathologic examination of the joint lavage fluids is useful in interpreting the TMD-associated inflammatory process from a cellular aspect. The aim of this study was to assess the TMJ lavage fluid cytopathologically in TMD patients. Thirty-nine patients, clinically diagnosed as TMD, were included in the present study. Clinical symptoms of the patients were recorded. Forty-four samples of TMJ lavage fluid were collected and paraffin-embedded cell sections were made by cell block tissue array method. Cytologic conditions in upper articular cavity of TMJ were cytopathologically diagnosed and were compared with the clinical symptoms of each patient. Cell components were detected in 22 of the 44 analyzed joint lavage fluids. There was a correlation between cytopathologic findings and clinical symptoms. Variety of cytopathology and inflammatory conditions in patients with similar clinical symptoms were also found. The results suggested that cytopathologic examination of the joint lavage fluids from TMD patients is helpful for gaining an understanding of the inner local conditions of TMJ at the cellular level.

To investigate the imaging features of synovial chondromatosis of the temporomandibular joint (TMJ), which is a rare benign arthropathy with cartilaginous proliferation.MATERIALS AND METHODS: Computed tomography and magnetic resonance imaging examinations of 34 patients with histopathologically confirmed primary synovial chondromatosis of the TMJ were reviewed retrospectively. Imaging features including the lesion epicentre, destruction/sclerosis of surrounding bone, calcification, periosteal reaction, osteophyte, lesion size, and joint space dimensions were assessed.RESULTS: Thirty-one of thirty-four patients (91.2%) showed the superior joint space as the lesion epicentre. For the mandibular condyle, more than one-third of patients (14/34; 41.2%) showed no destruction, and more than half of patients (19/34; 55.9%) showed no sclerosis. Conversely, >70% of patients showed destruction and sclerosis of the articular eminence/ glenoid fossa, while >80% of patients (28/34; 82.4%) presented with various calcifications, including the ring-and-arc (9/34; 26.5%) and popcorn (13/34; 38.2%) types. The mean joint space on the affected side was significantly larger than that of the unaffected side (p<0.001). More than three-fourths of patients (76.9%) experienced no interval increase in lesion size during an average of 1.6 years of follow-up.CONCLUSION: Synovial chondromatosis of the TMJ demonstrated several imaging features, including the lesion centre being located in the superior joint space, resultant articular eminence/glenoid fossa-oriented bone changes, ring-and-arc and popcorn calcification, joint space widening, and self-limiting growth. These imaging features may be helpful in differentiating synovial chondromatosis from other lesions of the TMJ.
