Abstract:
Pigmented villonodular synovitis (PVNS) is a relatively rare disease affecting synovium-lined joints. PVNS was first fully described in 1941 by Jaffe et al, who considered it a benign inflammatory state of the synovium of uncertain etiology. Reports of this disease in the temporomandibular joint (TMJ) are extremely rare. This report describes a case of a 78-year-old man affected by PVNS of the right TMJ. Clinical examination revealed the presence of a right-sided preauricular mass; a magnetic resonance imaging scan showed a mass located lateral to the right mandibular condyle, close to the TMJ capsule. The clinical and pathologic features of the case are described.

The mesenchymal stem cells differentiate into chondrocytes that form the hyaline cartilage, and later the cartilaginous model of the bone. This model further transforms into a bone. This process is known as endochondral ossification.
