      A 20-year-old female patient was referred to the department of oral and maxillofacial surgery at King Saud University for evaluation of a painless, expansile mass in the left mandible of 3 months duration. The patient's past medical history was unremarkable. Head and neck examination revealed left facial asymmetry with no paresthesia. Intraoral examination revealed the presence of an ulcerated exophytic nodular growth in the left premolar-molar region. The mass was red in color, firm in consistency, and bled minimally when touched. The surface of the lesion was irregular due to the indentation of the opposite upper teeth. Additionally, the lesion caused lingual displacement of the left second premolar. The involved teeth were vital and positive on percussion with a normal response to cold (Figure 1A).
