Odontogenic Keratocyst with Compound Odontome: A Rare Presentation

An odontogenic keratocyst (OKC) is a noninflammatory developmental cystic lesion of odontogenic origin that tends to penetrate the bone and nearby soft tissues. It also exhibits aggressive clinical behavior and a high recurrence rate. Odontomas are hamartomatous lesions occurring in the oral cavity, which may be either compound or complex, composed of enamel, dentin, and pulp, which resemble a normal tooth. They constitute about 22% of all odontogenic tumors of the jaw. We report a rare instance of a 17-year-old male patient, who was tentatively diagnosed with an odontogenic lesion. The patient complained of facial swelling and pain on the left side of his face for a month and had a histologic diagnosis of OKC associated with an impacted left mandibular lateral incisor and compound odontome. Not many cases of this type are reported in the literature. There is a need to explore the occurrence of such hybrid lesions.
