What are odontogenic keratocysts and how are they diagnosed?

Odontogenic keratocysts are usually noted as incidental radiographic findings. Radiographically they can be seen as unilocular or multilocular radiolucencies. They can be mistaken for other cysts such as residual cysts or a dentigerous cyst if they occur over an unerupted tooth. Relative incidence of odontogenic cysts.

What is odontogenic keratocyst?

Introduction. Odontogenic keratocysts (OKCs), first described by Philipsen in 1956 [1], are benign intraosseous lesions of odontogenic origin that account for about 10% of jaw cysts. They are characterised by an aggressive behaviour with a relatively high recurrence rate [2].

Is odontogenic keratocyst a true cyst?

An odontogenic keratocyst is a rare and benign but locally aggressive developmental cyst. It most often affects the posterior mandible and most commonly presents in the third decade of life.

What does Keratocyst mean?

Odontogenic keratocyst (OKC) is the cyst arising from the cell rests of dental lamina. It can occur anywhere in the jaw, but commonly seen in the posterior part of the mandible.

Is Keratocyst a tumor?

The keratocystic odontogenic tumor (KCOT), formerly known as the odontogenic keratocyst (OKC), received its new designation in order to better convey its neoplastic nature [1]. It is a benign developmental odontogenic tumor with many distinguishing clinical and histologic features.

Can keratocystic odontogenic tumor recur?

The Keratocystic Odontogenic Tumor (KCOT) is characterized by its high tendency to recur after surgical treatment. This is attributed to its infiltrative growth pattern and to the failure during surgery to remove the epithelial rests of the dental lamina or the daughter cysts [1-4].

Why is OKC recurrence high?

There are several possible reasons why OKC recur so frequently and require meticulous surgical planning and execution. The first of these is related to their tendency to multiplicity in some patients, including the occurrence of satellite cysts, which may be retained during an enucleation procedure.

Why do odontogenic keratocysts recur?

The odontogenic keratocyst (OKC) was first described and named by Phillipsen in 1956. It is one of the most aggressive odontogenic cysts of the oral cavity. OKC is known for its rapid growth and its tendency to invade the adjacent tissues including bone. It has a high recurrence rate of 16 to 30%.

Why is OKC called a primordial cyst?

The initial terminology for an odontogenic keratocyst (OKC) was "primordial cyst," as the origin of the lesion was thought to be the tooth primordium.

Why is OKC called KCOT?

The World Health Organization (WHO) has recommended the use of the term keratocystic odontogenic tumor (KCOT), rather than odontogenic keratocyst (OKC), because the former name better reflects the neoplastic behavior of the lesion.

What is an OKC tumor?

Abstract. The odontogenic keratocyst (OKC, currently designated by the World Health Organization as a keratocystic odontogenic tumor) is a locally aggressive, cystic jaw lesion with a putative high growth potential and a propensity for recurrence.

Which type of OKC is the most common?

Odontogenic KeratocystThe odontogenic keratocyst (OKC) is the most likely cyst to recur after treatment. ... There are two types of OKCs: a dentigerous type and a primordial type. ... The treatment of an OKC ranges from marsupialization, to enucleation, to enucleation with adjunctive treatment of the bony cavity, to resection.More items...

Is Odontogenic Keratocyst cancerous?

odontogenic keratocyst (OKC) is considered a benign cyst that can assume a locally aggressive and destructive behavior. Atypia of its lining is uncom- mon, and frank malignant degeneration is rare. Presence of these changes may remain clinically undetected and carry a significant influence on treatment and outcome.

The ICD code K090 is used to code Dentigerous cyst

A dentigerous cyst or follicular cyst is an odontogenic cyst - thought to be of developmental origin - associated with the crown of an unerupted (or partially erupted) tooth. The cyst cavity is lined by epithelial cells derived from the reduced enamel epithelium of the tooth forming organ.

What is an odontogenic keratocyst?

Odontogenic keratocyst. Micrograph of an odontogenic keratocyst. H&E stain. An odontogenic keratocyst is a rare and benign but locally aggressive developmental cyst. It most often affects the posterior mandible and most commonly presents in the third decade of life. Odontogenic keratocysts make up around 19% of jaw cysts.

Why is odontogenic keratocyst no longer considered a neo

Under The WHO/IARC classification, Odontogenic Keratocyst underwent the reclassification as it is no longer considered a neoplasm due to a lack of quality evidence regarding this hypothesis, especially with respect to clonality. Within the Head and Neck pathology community there is still controversy surrounding the reclassification, ...

What is the protein content of odontogenic keratocysts?

Aspirational biopsy of odontogenic keratocysts contains a greasy fluid which is pale in colour and contains keratotic squames. Protein content of cyst fluid below 4g% is diagnostic of odontogenic keratocysts. Smaller and unilocular lesions resembling other types of cysts may require a biopsy to confirm the diagnosis.

What is the diagnosis of a keratocyst?

Diagnosis. Classic look of an odontogenic keratocyst of the right mandible in the place of a former wisdom tooth. Well defined, unilocular, radiolucent lesion within the bone. Diagnosis is usually radiological. However, definitive diagnosis is through biopsy.

What is a nevoid basal cell carcinoma?

Nevoid basal-cell carcinoma syndrome. Multiple odontogenic keratocysts are a feature, and major diagnostic criteria, of nevoid basal cell carcinoma syndrome (NBCCS, also known as Gorlin-Goltz Syndrome). Almost all individuals with NBCCS have odontogenic keratocysts which require numerous treatments.

How many units are there in a keratocystic odontogenic tumour?

On a CT scan, the radiodensity of a keratocystic odontogenic tumour is about 30 Hounsfield units, which is about the same as ameloblastomas. However, ameloblastomas show more bone expansion and seldom show high density areas.

Why do keratocysts grow?

However, bony expansion is uncommon as odontogenic keratocysts grow due to increased epithelial turnover rather than osmotic pressure. When symptoms are present they usually take the form of pain, swelling and discharge due to secondary infection.
