Odontogenic myxoma of the maxilla: a case report

Odontogenic myxomas are rare tumours of the mesenchymal portion of developing tooth and account for 3–6% of all odontogenic tumours. Microscopically, odontogenic myxomas have a characteristic histologic appearance, which distinguishes it from other odontogenic tumours. However, it can mimic normal dental follicles of a developing tooth, from which it can be differentiated histologically by the nature of connective tissue and also by clinical and radiological appearances.

We present a case of a 30-year-old female with a large mass involving the left maxillary sinus. Histopathology showed features of odontogenic myxoma.

Early diagnosis of such lesions is critical for avoiding extensive surgical procedures and the subsequent impact on the patient’s quality of life.

Complete surgical excision is the treatment choice, which can be difficult owing to the tumour’s invasive borders. Hence, the patients should benefit from regular follow-ups.
