Terms & Conditions of Use

This case highlights the aggressive potential of calcifying odontogenic cysts, suggesting a malignant epithelial odontogenic ghost cell tumor. Further investigation is needed due to the patient refusing treatment for the remaining tumor.

Area of Science:

Oral pathology
Odontogenic tumors
Maxillary pathology

Background:

Odontogenic tumors can present as cystic lesions in the jaw.
Malignant transformation of odontogenic cysts is rare but documented.
Calcifying odontogenic cysts are a type of odontogenic tumor.

Observation:

A 57-year-old man presented with an expanding cystic lesion in the anterior maxilla.
The lesion caused destruction of local structures.
Microscopic examination revealed an aggressive epithelial odontogenic tumor.

Findings:

The tumor showed features of malignant transformation from an odontogenic cyst.
This case supports the malignant potential of calcifying odontogenic cysts.
An aggressive or malignant form of epithelial odontogenic ghost cell tumor is suggested.

Implications:

This case underscores the importance of recognizing aggressive odontogenic neoplasms.
Early diagnosis and treatment are crucial for managing such aggressive tumors.
Further research is needed to understand the behavior and metastatic potential of these tumors.
