Ameloblastoma is a odontogenic tumor of facial skeleton. It is around 11% of all jaw tumors. Common in 20-50 years age group although can occur at any age .Lower jaw is more common than upper jaw(4:1) .Posterior region of jaw is more common than anterior region. They are slow growing ,painless  in most patients . On radiology they are unilocular or multilocular lesions usually translucent.

Ameloblastoma are of three types

Unicystic Ameloblastoma


This develops in the epithelia wall of dentigerous cyst in posterior aspect of maxilla. Patients are younger than 30 years.Can be treated with enucleation and currettage.

Peripheral or extraosseous Ameloblastoma 

Arise from basal layer of surface epithelium overlying the tooth bearing portion of jaws. May be difficult to differentiate from basal cell or squamous cell carcinoma . Has a high recurrence rate (25 to 30%), has to be resected radically.

Conventional intraosseous Ameloblastoma

 Require radical resection,1 to 2 cm beyond margins of tumors.


Maxillary Ameloblastoma
Must be excised radically .Eye can be preserved but in aggressive tumors must be removed. After wide margin free excision appropriate reconstruction must be proformed

These horrifying pictures are of facial tumors suffered by patients of Xeroderma pigmentosum.This is a genetic condition in which body ability to repair genetic damage is greatly impaired. As a result theses children are greatly susceptible to damaging effects of UV rays. They develop facial skin tumors  or in other exposed part of body. This patient had these skin tumors which were excised and skin grafted. Bilateral neck dissection was done as it showed enlarged lymph nodes.
