Squamous cell carcinoma in a maxillary odontogenic keratocyst: A rare entity.
Odontogenic cysts in the maxilla are common but a malignant change in an odontogenic cyst is a comparatively a rare occurrence; however, these entities present with clinical and radiographic features similar to benign, expansible, central, odontogenic tumor, or cyst of the jaws. A patient reporting with squamous cell carcinoma arising from an odontogenic keratocyst of right maxilla has been worked up clinically, radiographically, and pathologically. The case was surgically managed and followed up. A 54-year-old male patient with a compressible, rapidly growing swelling of right maxilla was clinically diagnosed to be a case of odontogenic cyst. On radiologic examination it appeared similar to a cystic lesion. An incisional biopsy obtained from the cyst wall showed it to be odontogenic keratocyst with histologic evidence of malignant transformation. The pathogenesis of the tumor, the biologic progression, and prognosis and overall clinical and histopathogical features of this rare malignancy is reported and discussed.
