The purpose of this report is to document a case of unsuspected ameloblastoma involving the right man dibular subpontic region in a 38-year-old Cambodian female patient. This lesion was purportedly preceded by multiple radiolucencies which were diagnosed as radicular cysts and treated a few times in the past years by enucleation followed by endodontic therapy of the affected teeth. Bridgework r...

Ameloblastomas are tumors of odontogenic epithelial origin. The term unicystic ameloblastoma is used to describe cystic lesions with clinico-radiographic features resembling an odontogenic cyst, but histologically showing the presence of ameloblastomatous epithelium lining part of the cyst cavity. A large majority of lesions are found in the mandible, and usually cause a painless swelling of th...

Ameloblastoma is the most common odontogenic tumor, but the incidence of its metastasis is extremely low. We report a case of unicystic ameloblastoma metastasizing to the cervical lymph nodes. This patient pointed out a radiolucent cystic lesion with impacted wisdom tooth in the left mandibular region, and recieved enucleation of the cystic lesion and removal of the wisdom tooth. Histopathogica...

Ameloblastoma is a not uncommon tu mour reported in the clinical literature and is characterised by a multilocular cavity with ‘soap bubble’ pattern usually in the posterior body of the mandible. A review of the palaeopathology literature did not reveal any examples of ameloblastoma. In this paper, a probable case of ameloblastoma in a male skeleton, 45 –55 years at age of death, from Casserres...

Ameloblastoma is a rare, odontogenic neoplasm with benign histopathology, but extensive, local infiltrative capacity through the bone tissue it originates in. While the mechanisms of ameloblastoma invasion through the bone and bone absorption are largely unknown, recent investigations have indicated a role of the osteoprotegerin/receptor activator of nuclear factor kappa-B ligand regulatory mec...

Sister Mary Joseph's nodule is an important physical sign. It usually represents umbilical metastasis of intra abdominal malignancy. Its association with intra abdominal desmoplastic small round cell tumour is extremely rare. We describe a rare case of sister Mary Joseph's nodule associated with desmoplastic small round cell tumour. We conclude that differential diagnosis of Sister Mary Joseph'...

This article highlights features of ameloblastoma which could be mistaken for a malignant tumor. Ameloblastoma is usually multilocular but may also present itself as unilocular radiolucency. Ameloblastomas are nototrious for their local invasiveness and their tendency to recur. It shows an aggressive behavior leaving surgical resection as one of the most practical approach towards treatment. Al...

Odontogenic carcinomas of the maxilla are classified as malignant ameloblastoma, ameloblastic carcinoma, or primary intraosseous carcinoma. The term ameloblastic carcinoma is used to describe those ameloblastomas in which there is histological evidence of malignancy in the primary, recurrent, or metastatic tumour. The maxilla is an unusual site for ameloblastoma. This report is of a patient wit...

Peripheral ameloblastoma, a rare and unusual variant of odontogenic tumour, comprises about 2-10% of all ameloblastomas. The extraosseous location is the peculiar feature of this type of tumour, which is otherwise similar to the classical ameloblastoma. This paper describes a case of peripheral ameloblastoma in a 67-year-old female affecting the lingual alveolar mucosa of the mandibular 32-34 r...

Introduction: squamous odontogenic tumor is a rare benign locally infiltrative odontogenic tumor of epithelial origin and only a few cases, less than 50, have been reported in literature. the challenge is in diagnosing the tumor is due to its close resemblance to acanthomatous ameloblastoma and well differentiated squamous cell carcinoma. case report: Herein we report, not previously reported, ...
