A Case of Odontogenic Keratocyst in the Posterior Ramus and Body of the Mandible Mimicking Ameloblastoma

Pharmaceutical Science-Oral Medicine & Radiology

Abstract

The dental lamina gives rise to the odontogenic keratocyst (OKC), a common odontogenic cyst that affects the maxillofacial region.The OKC is distinct from other jaw cysts and is more likely to return when combined with aggressive clinical behavior. The recurrence ratein OKC is 25%–30%. In 2005, the World Health Organization (WHO) group categorized odontogenic keratocyst (OKC) as a tumor andproposed the abbreviation KCOT to differentiate the condition from the ortho keratinizing variant. The WHO reclassified KCOT as OKC in2017 based on data demonstrating non-neoplastic clinical behavior. The 30-year-old male in this case study has OKC in the ramus and body ofhis jaw, near the right mandibular molar tooth. When the patient reported to us, he complained of pain and swelling, 48 was clinically absent,and there was an enlargement of the buccal and lingual cortical plates. Palpation revealed tenderness in the region distal to 48. CBCT revealeda sizable radiolucent lesion, making it difficult to determine whether it was an odontogenic keratocyst or ameloblastoma in the body and lowerpart of the ramus on the right side. Histopathology findings corroborated OKC's diagnosis. As a precaution, the affected teeth were extracted,marsupialization was done, and an ongoing follow-up was done for an additional 1.5 years. There hasn't been a recurrence of OKC, and itshowed good healing. This case study aims to demonstrate the need for dentists to do in-depth investigations into each circumstance and offerpatients better treatment options with ongoing patient monitoring and follow-up. Enucleation, marsupialization, and other surgical techniquesare possible; however, in this case, our objective was to preserve the patient's mandible and facial features.
