Chondrosarcoma of the maxilla: A case report and review of literature.

We report a case of recurrent chondrosarcoma of the maxilla in a 29 yr old male patient. The lesion presented as a small diffuse swelling on the left maxillary anterior region which had progressed over a period of one year. On aspiration, a chondromyxoid matrix was noted with cells arranged singly or in groups.

The role of stroma in the expansion of odontogenic cysts and adenomatoid odontogenic tumor: A polarized microscopy study.

Objectives: To compare the polarization colors of collagen fibers of odontogenic keratocyst (OKC), radicular cyst, dentigerous cyst, and adenomatoid odontogenic tumor (AOT) with reference to their biological behavior.

Study Design: Twenty cases each of OKC, radicular cyst, dentigerous cyst, and AOT were stained with picrosirius red stain and studied under polarized light.

Results: A predominance of green to greenish yellow thick fibers was noted in OKC and AOT as compared to dentigerous cyst and radicular cyst.
