Juvenile fibromatosis of the temporomandibular joint: A rare case report

Abstract

Fibromatosis is the non-malignant proliferation of fibroblasts that aggressively invade adjacent tissues. It is composed of well-differentiated cells separated by considerable collagen and/or reticulin. The cause of this abundant growth is unknown, but many suspect hormonal or traumatic influences. When fibromatosis develops in the temporomandibular joint (TMJ) or adjoining tissues, its aggressive growth can compress the trachea and cause death. The management is difficult as it is perplexing to comprehend. Resection is the treatment of choice. The following case report presents a rare case of fibromatosis involving TMJ and its uneventful successful management.
