Calcifying Odontogenic Cyst with Complex Odontoma: Histological and Immunohistochemical Features
The calcifying odontogenic cyst (COC) is a rare odontogenic cyst. Only 2% of all odontogenic cysts and tumors are COC. COC associated with odontoma (COCaO) reported in 24% of COCs. COCaO presents a greater incidence in female, with a ratio of 2 to 1. The highest incidence of COCaO occurs during the second decade with a mean age of 16 years, most frequently occurring in the maxilla (61.5%). Here...
متن کاملImmunohistochemical analysis of the patterns of p53 and PCNA expression in odontogenic cystic lesions.
OBJECTIVE the role of p53 expression in odontogenic lesions has not been fully determined, but has been associated with cell proliferation. The purpose of this study was to analyze p53 and proliferating cell nuclear antigen (PCNA) expression in 4 different odontogenic lesions. DESIGN expression of p53 and PCNA was analyzed in radicular and dentigerous cysts, odontogenic keratocysts, and calci...
متن کاملp53 and PCNA Expression in Keratocystic Odontogenic Tumors Compared with Selected Odontogenic Cysts
p53 and PCNA expression in keratocystic odontogenic tumors compared with selected odontogenic cysts Summary: The aim of this study was to evaluate p53 and PCNA expression in different odontogenic lesions regarding their different clinical behaviors. Slices prepared from 94 paraffin-embedded tissue blocks (25 radicular cysts (RC), 23 dentigerous cysts (DC), 23 keratocystic odontogenic tumors (KC...
متن کاملMyofibroblasts in calcifying odontogenic cyst and dentigerous cyst
Introduction:Calcifying odontogenic cyst (COC) is an odontogenic cyst that sometimes shows aggressive behavior, while dentigerous cyst (DC) always has a benign nonaggressive course. There are evidences that myofibroblasts are involved in invasion and their role in biologic behavior of odontogenic cysts has been less understood. So, the aim of the present study was to compare th...
متن کاملRecurrent Peripheral Calcifying Cystic Odontogenic Tumor (Calcifying Odontogenic Cyst)
Peripheral calcifying cystic odontogenic tumor (PCCOT) is a rare odontogenic lesion, which represents about 1% of jaw cysts. Here we report clinicopathologic, radiographic and CT scan images of a new case of recurrent large PCCOT located in mandibular gingiva in a 77-year-old male with history of a nodular mass in the same area, which had been completely excised 3 years ago. In reviewing the...
