[Mandibular fibromyxoma].

Fibromyxoma of the jaw is a rare neoplasm that may have the radiologic pattern of an aggressive lytic process despite its benign biological behaviour. The lesion is most common between the ages of 10 and 50. We report a case of fibromyxoma of the jaw in a 56 years old woman, with histologic and histochemical study. The case has clinical and statistical relevance for its unusual age of occurrence.
