ABSTRACT
We report a case of fibromyxoma of the mandible, a rare benign odontogenic tumor. Our patient presented in the first trimester of pregnancy with a large mass in the right body of the mandible exhibiting displacement of teeth and destruction of an extensive area of the mandibular bone. The mass was biopsied and diagnosed as a fibromyxoma. The large size of the tumor dictated a wide mandibular resection. We will review the clinical, radiographic, and histologic features of fibromyxoma and discuss its differential diagnoses. In addition, we will provide an overview of patient management. Fibromxyoma is a benign gnathic tumor that can be locally aggressive. To ensure appropriate treatment, it is important to distinguish this neoplasm from other mimickers in which myxoid, spindle mesenchymal cell proliferation is prominent.
