Zhou J, Wang L, Chen Z, Qiu J, Dong Q - Oncol Lett (2014)

Bottom Line: Keratocystic odontogenic tumors (KCOTs), formally known as odontogenic keratocysts, are benign developmental tumors that are found primarily in the mandibular molar region and ascending ramus.Recurrence has not been observed within the eight-month follow-up period.The present study discusses the clinical features and surgical management of this case.

ABSTRACT
Keratocystic odontogenic tumors (KCOTs), formally known as odontogenic keratocysts, are benign developmental tumors that are found primarily in the mandibular molar region and ascending ramus. The disease is characterized by aggressive growth and a high recurrence rate following surgical treatment. The present study reports the rare case of a 25-year-old male with a giant KCOT involving the right zygoma, maxillary bone and maxillary sinus. The tumor was removed using a modified treatment of enucleation, grinding and cryotherapy. Recurrence has not been observed within the eight-month follow-up period. The present study discusses the clinical features and surgical management of this case.

Mentions: A 25-year-old male presented to the Qingdao Municipal Hospital (Shandong, China) with a two-month history of painless swelling on the right side of the face. The medical history of the patient was unremarkable. On clinical examination, a large swelling was identified on the right side of the face that was hard and bony on palpitation. A CT scan revealed a giant, multilocular and hypodense lesion of ~6.5×5.0 cm in size, with a well-defined margin (Fig. 1). The lesion involved the majority of the right maxillary bone, maxillary sinus and zygomatic bone. The third molar tooth was completely impacted (Fig. 1). Based on these observations, a tentative diagnosis of a cyst was proposed.
