A CASE REPORT OF ODONTOGENIC KERATOCYST IN ANTERIOR MANDIBLE (original) (raw)

Odontogenic Keratocyst: A Rare Presentation in Anterior Maxilla

Journal of the College of Physicians and Surgeons Pakistan, 2020

The odontogenic keratocyst is an enigmatic developmental cyst that deserves special attention. It has characteristic histopathological and clinical features; but, what makes this cyst special is its aggressive behavior and high recurrence rate. Odontogenic keratocyst is a benign odontogenic cyst, commonly affecting the mandible. These lesions have posed a great difficulty for the surgeons and pathologists. Few cases affecting the maxilla are also reported. Literature search suggests that odontogenic keratocysts may affect maxillary posterior and canine region. The present case reports a lesion of odontogenic keratocyst occuring in the maxillary incisor region, crossing midline which was initially misdiagnosed as infected residual cyst. After careful evaluation, it was reported as an odontogenic keratocyst.

Bilateral odontogenic keratocyst of the mandible

Journal of maxillofacial and oral surgery, 2014

Odontogenic keratocyst (OKC) is a cyst of dental origin with an aggressive clinical behavior, having high recurrence rate. Multiple cysts are associated with bifid-rib basal cell nevus syndrome (Gorlin syndrome). We present a case of bilateral odontogenic keratocyst in a cleft lip patient.

Odontogenic Keratocyst Mandible An Interesting Case report and Literature review

Ent scholar, 2014

The term odontogenic keratocyst was first described by Philipsen in 1956. This cyst actually arises from the cell rests of dental lamina. It can occur anywhere in the jaw but is commonly seen in the posterior part of the mandible. Since the clinical features and radiological appearance are not characteristic this condition is commonly misdiagnosed. This is more so when the lesion is related to the nonvital tooth. Odontogenic keratocyst has been rechristened as keratocystic odontogenic tumor by WHO working group in 2005. This was necessitated to differentiate this lesion from its orthokeratinizing variant which is currently considered as odontogenic cyst. This case report discusses odontogenic keratocyst of mandible.

Ortho keratinized Odontogenic Cyst of Mandible: A Rare Case Report

Shahid Beheshti University Dental Journal, 2015

Objective: The Ortho keratinized Odontogenic Cyst (OOC) is a rare lesion originates from dental lamina and clinically, it may be mistaken for many other odontogenic cysts and Tumors. Microscopically, It should be distinguished from KCOT because of differences in biologic behavior and histologic features. Case: An interesting case of OOC arising in the edentulous mandibular right first premolar region of a 55-year-old woman is reported. Under the initial clinical diagnosis of a residual cyst, the excisional biopsy was performed. Because of detection of an orthokeratinized epithelium lining, a definite diagnosis of OOC was made. Conclusion: Microscopic examination is crucial for making the correct diagnosis of such lesions, therefore establishing patients' prognosis accurately.

Odontogenic keratocyst- Mimicking residual cyst in maxilla

Journal of Oral Medicine, Oral Surgery, Oral Pathology and Oral Radiology

OKC was classified as cystic lesion by WHO in 1971 & 1991, based on aggressive nature, growth pattern, clinical, histological and immunohistochemical nature in 2005 they again classified it as benign lesion, however in 2017 WHO head and neck pathology reclassified it as cystic lesion. It more commonly occurs in posterior mandible and rarely occurs in maxilla, in this case occurrence of OKC in maxillary posterior region is very rare with distinctive expansion and lifting of maxillary sinus floor without perforating in edentulous area makes it more difficult to detect and justify from residual cyst. Here a 65 years old patient came with chief complaint of pus discharge from upper left posterior region since 7 months, having a small opening in edentulous ridge, which provisional diagnosis was given as residual cyst later after excision of lesion and histopathological analysis it was given as OKC.

Odontogenic keratocyst: What is in the name?

Journal of Natural Science, Biology and Medicine, 2013

The classification of odontogenic cysts is complicated and can create confusion for both clinicians and pathologists. The odontogenic keratocyst (OKC) is an enigmatic developmental cyst that deserves special attention. It has characteristic histopathological and clinical features; but, what makes this cyst special is its aggressive behavior and high recurrence rate. Despite of many classifications and nomenclature, unfortunately the clinicians still have to face difficulties in the management of this commonly found jaw lesion. This article is an effort to provide an overview of various aspects of OKC with emphasis on nomenclature, recurrence, molecular aspects, and management of OKC.

Odontogenic keratocyst: imaging features of a benign lesion with an aggressive behaviour

Insights into imaging, 2018

The latest (4th) edition of the World Health Organization (WHO) Classification of Head and Neck Tumours, published in January 2017, has reclassified keratocystic odontogenic tumour as odontogenic keratocyst. Therefore, odontogenic keratocysts (OKCs) are now considered benign cysts of odontogenic origin that account for about 10% of all odontogenic cysts. OKCs arise from the dental lamina and are characterised by a cystic space containing desquamated keratin with a uniform lining of parakeratinised squamous epithelium. The reported age distribution of OKCs is considerably wide, with a peak of incidence in the third decade of life and a slight male predominance. OKCs originate in tooth-bearing regions and the mandible is more often affected than the maxilla. In the mandible, the most common location is the posterior sextant, the angle or the ramus. Conversely, the anterior sextant and the third molar region are the most common sites of origin in the maxilla. OKCs are characterised by ...

Odontogenic Keratocyst Diagnosis and Management: A Case Report

Zenodo (CERN European Organization for Nuclear Research), 2022

Odontogenic keratocyst (OKC) is a developmental, non-inflammatory, chronic cystic lesion of odontogenic origin which is considered aggressive due to its genetic abnormalities and biological behavior being consistent with neoplastic progression. OKC clinically appears as a swelling with or without pain, occurring in the jaw bones with greater predilection towards mandible. Radiographically appearing as unicystic or multicystic radiolucency with anteroposterior growth of the lesion in the medullary spaces. Histologically the presence of parakeratin and the 'picket fence' appearance of the basal cell layer is unique to this lesion. Various treatment modalities have been put forth but no specific treatment has been regarded as the best. The goal of this paper is to create awareness about the aggressive nature of the OKC and to throw a light on its management.

Odontogenic Keratocyst- a Review on Various Treatment Modalities

International Journal of Biology, Pharmacy and Allied Sciences, 2020

However In 2017, the new WHO classification of Head and Neck pathology reclassified OKC into cyst category. Epidemiologically OKC accounts for approx. 7.8 % of all cyst of the jaw and incidence vary from 4-16.5%. It occurs at all ages with peak incidence in 2nd and 4th decade of life. it predominantly occurs in white population with male :female ratio of 1.6:1. Location wise it is most commonly seen twice in mandible as compared to maxilla. In mandible it occurs usually in angle-ascending ramus region (69-83%). Mandibular cyst crosess the mid line and maxillary cyst may involve sinus and nasal floor, premaxilla and maxillary third molar region. OKC may arise from temporomandibular joint also.
