Abstract: Myxoma is a benign tumor of mesenchymal origin that most commonly arises in the heart. It can arise in various sites including the subcutaneous tissue, bone, skin, and muscles. Myxomas in the head and neck region predominantly occur in the maxilla or mandible, accounting for 76% of the cases, while occurrences in the soft tissues are extremely rare. The floor of the mouth in the head and neck region is the rarest site for the occurrence of soft tissue myxomas. In the international literature, only two cases have been reported, and there have been no reported cases in the domestic literature. In this paper, we report, with a review of literatures, a case of a 74-year-old female patient who presented with a mass lesion found beneath the left mandible and was finally diagnosed with a myxoma.
