Skin Cancer

Skin Cancer

Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.
Basal Cell Carcinoma (BCC): BCC is the most common type of skin cancer, accounting for about 80% of cases. It typically develops in...

Background:

Ameloblastoma is the most common odontogenic tumor, originating from odontogenic epithelium.
Despite being benign, it exhibits aggressive invasive growth and a high recurrence rate.
It accounts for 11% of all odontogenic tumors and 1% of jaw tumors.

Observation:

A case of ameloblastoma involving the entire ramus and part of the mandibular body is presented.
The tumor caused root resorption of adjacent molars and enveloped an unerupted third molar, mimicking a dentigerous cyst.
The lesion demonstrated extensive invasion, extending to the mandibular base.

Findings:

Surgical resection of the extensive ameloblastoma was performed.
A contralateral sixth costochondral rib graft was utilized for reconstruction.
Histopathological analysis confirmed plexiform ameloblastoma.

Implications:

This case underscores the aggressive nature and diagnostic challenges of ameloblastoma, particularly large or unusually presenting lesions.
Successful surgical management and reconstruction are crucial for functional and aesthetic outcomes.
Further research into the biological behavior and treatment modalities for recurrent ameloblastoma is warranted.
