Objectives: To focus on distribution of different histologic types of odontogenic cysts (OCs), patient gender and age, and cyst location in an Iranian population and compare results with others studies in different geographic locations and/or racial populations. Materials and Methods: A 40-year retrospective study of 1189 patients with OCs that were diagnosed from 1971 to 2011 in the Department...

The combined epithelial odontogenic tumor is known to be an uncommon lesion characterized by the synchronous presentation of typical histological features of adenomatoid odontogenic tumor, calcifying epithelial odontogenic tumor, or Pindborg tumor. Combination between other types of odontogenic tumors has occasionally been reported in the literature. In this work we report 2 cases of adenomatoi...

BACKGROUND Pigmented intraosseous odontogenic lesions are rare with only 47 reported cases in the English literature. Among them, pigmented calcifying cystic odontogenic tumor, formerly known as calcifying odontogenic cyst, is the most common lesion with 20 reported cases. METHODS A case of pigmented calcifying cystic odontogenic tumor associated with odontoma occurring at the mandibular cani...

Peripheral Calcifying Odontogenic Cyst (PCOC) is the extraosseous form of calcifying odontogenic cyst that limited to peripheral soft tissue without bony involvement. This case report presents a PCOC manifested as progressive growth gingival mass in young male treated with excisional biopsy. Histological examination confirmed diagnosis presence characteristic ghost cells and sporadic calcificat...

The human jaw is an exclusive habitat for odontogenic lesions. Ghost cells associated odontogenic lesions are a diverse group with a variety of presentations in the jaws. Calcifying cystic odontogenic tumor is a benign cystic neoplasm of odontogenic origin which demonstrates ghost cells in the epithelial component. This tumor sometimes mimics the features of a cyst clinically and radiographical...

In recent years, there have been published clinical reports dealing with cysts or tumors of the odontogenic character the extract of which revealed pathologic keratinizing or calcifying changes in the light of histopathologic examination Cl, 6, 8, 9, 10, 11, 12). These pathologic changes are said to give quite different histopathologic findings from those of the radicular cyst, follicular cyst ...

although aneurysmal bone cysts and calcifying odontogenic cysts accompanied with other lesions are reported in the literature, the simultaneous occurrence of these two distinct lesions has not been reported. to the best of our knowledge, this is the first report describing co-occurrence of these two lesions located in the left mandibular ramusin a 36-year-old woman.

Hybrid tumors are very rare tumors composed of two different tumor entities, each of which conforms to an exactly defined tumor category. A 14-year-old boy was referred for an intraosseous painless lesion with a histopathological feature of multiple odontogenic lesions including calcifying odontogenic cyst, complex odontoma and ameloblastic fibro-odontoma. The final diagnosis considered to be a...

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...

  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...
