Ameloblastoma of the jaws: a critical reappraisal based on a 40-years single institution experience.
The 40-years of experience in a single institution with the treatment of previously untreated ameloblastoma have been reported, followed by a management protocol. Retrospectively, 25 consecutive patients treated between 1969 and 2009 have been analyzed. In 11 patients, a preoperative diagnosis of ameloblastoma was available. In the remaining 14 patients the diagnosis of ameloblastoma was a post...
ameloblastomas are slow growing, locally invasive, benign odontogenic tumors of an epithelial origin, accounting for approximately 1% of all oral tumors. a 40-year-old man presented with a chief complaint of a swelling over the left side of his face of 4 years’ duration. on examination, gross facial asymmetry was detected, and a well-defined swelling was noted intraorally involving the left max...
Ameloblastoma is true odontogenic tumor of epithelial origin, which is described as locally aggressive with varying chances of recurrence. It is believed to derive from enamel organ, remnants of dental lamina, lining of odontogenic cysts, or basal cells of oral epithelium. Radiologically, it may present as unilocular or multilocular radiolucency commonly. Although conventional ameloblastoma pre...
Ameloblastoma is a neoplasm of odontogenic epithelium, especially of enamel organ-type tissue that has not undergone differentiation to the point of hard tissue formation. It accounts for approximately 10% of all tumors originating from gnathic bones. It exhibits diverse microscopic patterns which occurs either singly or in combination with other patterns. Granular cell ameloblastoma is a rare ...
Thank you for your attention to our study and wonderful questions. Our reply is as below. Question) The title of the article states that the case is about a glandular odontogenic cyst (GOC) mimicking am-eloblastoma. The history (slow expansion, no symptoms) and the radiographic appearance of the lesion (lobulated, well-defined margin, erosion and perforation of the lin-gual cortex, root resorpt...
Ameloblastoma is a slow-growing and locally invasive epithelial odontogenic tumor of the jaw that runs benign course in most cases. Granular cell ameloblastoma rare subtype ameloblastoma, showing granular transformation its cytoplasm. It considered as an aggressive variant ameloblastoma. Herein, we report case 34-year-old male patient who presented with swelling left cheek for 1-year duration r...
Conservative Decompression Management with Functional Appliance in Pediatric Plexiform Ameloblastoma
Ameloblastoma is an infiltrative benign neoplasm in the mandible or maxilla that locally aggressive with rare metastasizing capacity. This lesion most common tumor of odontogenic epithelium. However, its occurrence children low, representing only 10–15% all reported ameloblastoma cases. In treating such neoplasms pediatric patients, preservation vital structures as inferior alveolar nerve (IAN)...
Desmoplastic melanomas are rare amelanotic melanomas that usually occur on skin with sun exposure. In this report, we present a 72-year-old man who presented with a desmoplastic melanoma of the penis. To our knowledge this represents the first reported case of primary desmoplastic melanoma of the penis. We discuss the pathologic differential and histologic evaluation.
Ameloblastoma is an odontogenic tumor of high frequency and usually occurs as an intraosseous growth. Ameloblastomas frequently recur, sometimes undergoing malignant transformation. These tumors are usually characterized as being multilocular, of the follicular type histopathologically, and invading strongly at the border region of the tumor. More than 10% p53-positive tumor cells give a progno...
Unicystic ameloblastoma is believed to be less aggressive and responds more favorably to conservative surgery than the solid or multicystic ameloblastomas. This report is a rare case of unicystic ameloblastoma of the maxilla that was treated by enucleation under suspicion of a radicular cyst related to a dens in dente. The neoplastic nature of the lesion became evident only when the enucleated ...
