How is Unicystic Ameloblastoma treated?
Treatment. All the cases were treated conservatively either with enucleation with or without bone curettage or marsupialization followed by enucleation under General Anesthesia. Marsupialization was chosen in two patients due to young age (10 and 9 years), involved erupting teeth and facial asymmetry.
What is a Unicystic Ameloblastoma?
Unicystic ameloblastoma (UA) refers to those cystic lesions that show clinical, radiographic, or gross features of a mandibular cyst, but on histologic examination show a typical ameloblastomatous epithelium lining part of the cyst cavity, with or without luminal and/or mural tumor growth.
Is Unicystic Ameloblastoma cancerous?
Ameloblastomas are benign tumors whose importance lies in its potential to grow into enormous size with resulting bone deformity.
What is Multicystic ameloblastoma?
The multicystic ameloblastoma is a benign epithelial odontogenic tumor of the jaws that is slow-growing, locally aggressive and accounts for approximately 10% of all odontogenic tumors in the jaw. Most cases are diagnosed in young adults, with a median age of 35 years, and no gender predilection.
What is mural ameloblastoma?
Mural ameloblastoma is a subtype of Unicystic Ameloblastoma characterised by the expansion or infiltration of tumour nodules into the fibrous wall of the cyst. The behaviour of this subtype is highly aggressive, with a risk of recurrence comparable with that of Conventional Ameloblastoma.
What is the cause of ameloblastoma?
Causes. The cause of ameloblastoma is not understood. Causes may include injury to the mouth or jaw, infections of the teeth or gums, or inflammation of these same areas. Infections by viruses or lack of protein or minerals in the persons diet are also suspected of causing the growth or development of these tumors.
Why is it called ameloblastoma?
Ameloblastoma is a rare, benign or cancerous tumor of odontogenic epithelium (ameloblasts, or outside portion, of the teeth during development) much more commonly appearing in the lower jaw than the upper jaw. It was recognized in 1827 by Cusack.
Who odontogenic tumor classification?
The 1971 WHO classification contained “odontogenic tumors, odontogenic cysts and allied lesions”. In 1992, such classification was titled “odontogenic tumors”, but still included odontogenic cysts and allied lesions.
What is compound odontoma?
Compound odontomas are regularly calcified tissue that bear similarity to teeth or appear as a collection of small teeth. We report a rare case of compound odontoma in the mandible of an adult patient with clinical and radiological features and a review of the literature.
How is unicystic ameloblastoma (UA) classified?
Histological classification of unicystic ameloblastoma (UA) subtypes according to Ackermann et al. [10]. (1) Fibrous cyst wall lined by ameloblastomatous epithelium; (2) intralumenal proliferation of `papillomatous’ mass of plexiform, ameloblastomatous tissue; (3a) intramural nodule with islands of infiltrating ameloblastoma tissue.
What are the treatment options for unicystic ameloblastoma?
Perhaps the most important consideration regarding unicystic ameloblastoma is that of biologic behaviour. It has been widely stated that these lesions are less aggressive than their solid or multicystic counterparts and should be treated by enucleation or curettage.
What are the different types of ameloblastomas?
Macroscopically and microscopically there are two types of intraosseously located ameloblastomas, the solid or multicystic ( SMA) and the unicystic ( UA) variant. Radiographically, the unilocular pattern is more common in the unicystic variant than the multilocular, especially so in cases associated with tooth impaction.
Can unicystic ameloblastoma recurrence be delayed?
Moreover, recurrence of unicystic ameloblastoma may be long delayed and a long-term post-operative follow up is essential for proper management of these patients. Here we are presenting a case of unicystic ameloblastoma in a 18 year old female patient. Keywords: Luminal proliferation, stellate reticulum, unicystic ameloblastoma INTRODUCTION
