Abstract
Odontogenic myxomas (OM), also called odontogenic fibromyxomas, are rare tumours of the jawbones. They are benign tumours that can be locally invasive and aggressive, but seldom undergo malignant transformation and do not give rise to metastases. They are often asymptomatic and present as painless swelling. We present herein the case of a 24-year-old patient, with an incidental finding of a maxillary lesion. The lesion expanded to the surrounding soft tissues of the face, the maxillary sinus, the nasal cavity and the ethmoidal cells. After confirmation of OM on biopsy, the patient underwent an extended right radical en bloc maxillectomy with immediate reconstruction of the inferior orbital rim. A literature review of clinical symptoms, radiological presentation, differential diagnosis and surgical management of OM is discussed.
Highlights
Odontogenic myxomas (OM) are benign tumours first described in the literature by Thoma and Goldman in 1947 [1]
We present the case of an odontogenic myxoma of the maxilla in a 24-year-old woman with a brief review of the literature, focusing on clinical symptoms, radiological presentation, differential diagnosis and surgical management of OM
Teeth displacement and resorption were present. Such radiographic features were consistent with a differential diagnosis of odontogenic myxoma, central giant cell granuloma, central mucoepidermoid carcinoma, ameloblastoma, odontogenic keratocystic tumour, and other rare entities
Summary
Odontogenic myxomas (OM) are benign tumours first described in the literature by Thoma and Goldman in 1947 [1]. (2014) Extensive Odontogenic Myxoma of the Maxilla: A Case Report and Review of Literature. They are rare in patients under the age of 10 or over the age of 50 [5]. The most common affected site is the posterior mandible [3] [7] [8] They can be locally invasive and aggressive, but are believed by some not to undergo malignant transformation nor give rise to metastases [9]. We present the case of an odontogenic myxoma of the maxilla in a 24-year-old woman with a brief review of the literature, focusing on clinical symptoms, radiological presentation, differential diagnosis and surgical management of OM
