Desmoplastic ameloblastoma of maxilla: a case report
2010
Ameloblastoma is the most common neoplasm affecting the jaws, arising from the odontogenic epithelium. Despite its locally aggressive nature, it is considered to be benign. The chief histopathological variants of ameloblastoma are the follicular and plexiform types, followed by the acanthomatous and granular cell types. Uncommon variants include desmoplastic, basal cell, clear cell ameloblastoma, keratoameloblastoma and papilliferous keratoameloblastoma. When the desmoplastic type co-exists with other types, it is called as “hybrid” ameloblastoma. There are significant anatomic, histopathological and radiological differences between desmoplastic ameloblastoma and the classical type. The pur…
Extreme ameloblastoma of the mandible with hypoproteinemia. A case report and review of clinicopathological features
2011
Ameloblastoma is a tumor of odontogenic epithelium. It has an intermediate malignant potential, thus positioning it in a gray zone between benign and malignant neoplasms. Invasive ameloblastomas of excessive size are rarely confronted. Although these ameloblastomas are benign, they are life threatening. Many have eventuated in death due to airway obstruction, starvation from restriction of feeding, and complications of hypoproteinemia. These tumors cause significant expansion of skin and lips [tissue expanders]. Due to its metabolic demands, a tumor of enormous size will have numerous feeding vessels. Patients with extreme ameloblastomas are usually from rural areas of developing countries …
