Background: Jaw cysts and cyst-like lesions cause facial deformity, destruction of dental tissues and affect masticatory and phonation functions. These adversely erode patients’ psycho-social status; create low self-esteem and may change one’s facial identity and appearance. Objective: To determine the histopathologic characteristics, variants and demographic pattern of jaw cysts and cyst-like ...

BACKGROUND The term "primary intraosseous squamous cell carcinoma" was introduced in 2005 by the World Health Organization with three subcategories. Squamous cell carcinoma arising from the lining of an odontogenic cyst is one important rare subcategory of such lesions with an incidence of 0.01 to 0.02%. Furthermore, the appearance of such malignancy in an odontogenic tumor such as keratocystic...

Intraosseous mucoepidermoid carcinoma is a rare tumor which affects women more than men and is more common in the mandible. The radiological examination reveals a well-defined unilocular or multilocular radiolucent lesion. This tumor may resemble a glandular odontogenic cyst, particularly in incisional biopsies. The accurate diagnosis of these lesions is imperative because the subsequent treatm...

Odontogenic keratocyst (OKC) is one of the most aggressive odontogenic cysts owing to its relatively high recurrence rate and its tendency to invade adjacent tissue. Radiographically odontogenic keratocyst can be of different types – follicular, envelopmental, replacemental, extraneous and collateral.The biological behaviour, prognosis, recurrence and therapeutic approaches vary in different st...

BACKGROUND CD166 is a glycoprotein of an immunoglobulin super family of adhesion molecules that has been associated with aggressive characteristics and high recurrence rate of tumors. Different odontogenic lesions exhibit considerable histological variation and different clinical behavior. In an attempt to clarify the mechanisms underlying this different behavior, the present study investigates...

Odontogenic keratocyst (OKC) is a common developmental odontogenic cyst affecting the maxillofacial region. Multiple OKCs are usually seen in association with nevoid basal cell carcinoma syndrome (NBCCS) but approximately 5% of patients with OKC have multiple cysts without concomitant syndromic presentation. This report represents a case of multiple OKCs in a non-syndromic patient.

Context: Developmental odontogenic cysts account for 25% of all odontogenic cysts of the jaw. They are commonly associated with impacted or embedded teeth like mandibular/maxillary third molar and maxillary canines. Dentigerous cyst (DC) is a common developmental odontogenic cyst, but its inflammatory variant is quite rare. Settings and design: The representative tissue received was 10% formali...

BACKGROUND Odontogenic keratocyst (OKC) is a developmental odontogenic cyst with an aggressive clinical behavior suggesting a change in its terminology from a cyst to a tumor and has now been renamed as keratocystic odontogenic tumor (KCOT). The purpose of this study was to assess and compare angiogenesis in ameloblastoma and OKC. MATERIALS AND METHODS Angiogenesis was assessed by studying th...

Calcifying odontogenic cyst (COC) is an uncommon benign cystic neoplasm of odontogenic origin, which shows extensive diversity in its clinico-pathological appearances and biological behavior. It most commonly occurs in broader age group of 1-82 years in anterior part of jaws which is classically described by presence of ghost cells. There are variants of COC according to clinical, histopatholog...
