Ameloblastoma is a benign odontogenic neoplasm which frequently affects the mandible. The term ameloblastoma includes several clinico-radiological and histological types. Apart from the most commonly encountered clinicopathologic models there are few variants, whose biological profile is unknown or not elicited. The reason for lack of understanding is the scarcity of case report published in th...

OBJECTIVE The aim of this study is to evaluate the caveolin-1 expression in a group of odontogenic cysts and tumors. MATERIAL AND METHOD In this cross-sectional study, the expression of caveolin-1 was evaluated immunohistochemically in 75 samples including 18 cases of dentigerous cyst, 18 odontogenic keratocysts, 3 orthokeratinized odontogenic cysts, 2 calcifying odontogenic cysts and 34 amel...

The lining of an odontogenic cyst may show potential for neoplastic transformation to non odontogenic malignancies like squamous cell carcinoma and mucoepidermoid carcinoma and also odontogenic tumors like ameloblastoma and adenoamatoid odontogenic tumor (AOT). Unicystic ameloblastoma is a single cystic cavity lesion which shows ameloblastomatous differentiation in the lining. The clinical and ...

malignant transformation of ameloblastomas arising from an odontogenic cyst or de novo is wellrecognized. malignancies in ameloblastomas may involve metastasis or a local dysplastic change in the tissue. the latter are classified as ameloblastic carcinomas. a 75-year-old male presented with a mandibular cystic swelling, with no evidence of metastasis. dysplastic ameloblastic cells with spindlec...

Ameloblastoma is a benign tumor; whose importance lies in its potential to grow to enormous size with resulting bone deformity. Unicystic ameloblastoma (UA) is a less encountered variant of amelobastoma. The neoplastic nature of the lesion becomes evident only when the enucleated material is available for histologic examination. Although its predilection is for the posterior mandibular region, ...
