Nodular fasciitis of the temporomandibular joint: a case report

Nodular fasciitis is a relatively rare benign lesion of the soft tissue, which often presents in the fascia or deep subcutaneous tissues. It most commonly presents in the upper extremities and trunk and the head and neck region, particularly in younger patients. Its pathogenesis is poorly understood and it is predominantly thought to be a reactive lesion, although some have suggested that it may be a benign neoplasm. Advances in molecular testing and imaging have greatly assisted diagnosis. We discuss the benefits of ubiquitin-specific protease 6 (USP6) gene rearrangement testing and magnetic resonance imaging (MRI) to aid this uncommon diagnosis.
