Aim: Aim of this case report is to discuss and identify a rare diagnosis yet seen commonly in oral and maxillofacial field and often misdiagnosed as odontogenic keratocyst (OKC). Background: The term “odontogenic keratocyst” was first described by Philipsen in 1956. This was then modified by World Health Organization (WHO) in 2005 as “odontogenic unicystic” or “multicystic intraosseous tumor” with a distinctive parakeratinized stratified squamous epithelial lining and the propensity for aggressive and infiltrative activity. It has a male predilection and bimodal age distribution. Orthokeratinized OKC makes up to 2.1% of all the cystic lesions of the jaws. Case description: A young female patient aged 18 years reported to our department with the chief complaint of pus like discharge from upper left back tooth region for the past 2 months. After all the clinical, radiological, and histopathological findings, the patient was then diagnosed with orthokeratinized odontogenic cyst (OOC) of posterior maxilla. Conclusion: Orthokeratinized odontogenic cyst has clinical, histological, and biological characteristics that distinguish it from OKC, including better prognosis and decreased recurrence rate. Clinical significance: It is important to distinguish between OKC and OOC as the latter shows less chances of recurrence and less scope for malignancy transformation.
