Anomalous Jaw Tumour Progression from Multiple Complex Odontomas to Cemento-ossifying Fibroma - A Case Report.

RATIONALE

Odontomas are benign, asymptomatic odontogenic tumours, while ossifying fibromas are fibro-osseous lesions from the periodontal ligament. The rare transition from odontomas to an ossifying fibroma in the same jaw highlights the need for long-term follow-up.

PATIENT CONCERNS AND DIAGNOSIS

A young adult with multiple odontomas, one of which later changed into a different type of bone-related tumour; ossifying fibroma. The first odontoma was surgically removed 10 years ago, followed by the development of a cemento-ossifying fibroma from an anterior odontoma.

TREATMENT AND OUTCOMES

The fibroma was excised via an intraoral vestibular incision, and the lesion was completely enucleated. Paraesthesia occurred postoperatively due to proximity to the inferior alveolar and lingual nerves but resolved within 3 - 4 weeks. The patient experienced a significant reduction in swelling and improved facial symmetry, with long-term follow-up required for recurrence monitoring.

TAKE-AWAY LESSONS: This case emphasises the potential evolution of odontogenic tumours and the importance of vigilant monitoring.
