Squamous Odontogenic Tumor of Maxilla - A Rare Case Report

Squamous odontogenic tumors (SOTs) are rare benign odontogenic epithelial neoplasms with very low recurrence rate and absolutely no malignant potentiality. The average age at presentation is 38.2 year, though a wider age group of affection from 1st to 8th decade is noted. The common presentation is a slow growing, painless expansile swelling in the maxilla or mandible. Owing to its unique radiological and distinct histopathological features of nests of bland looking squamous epithelial cells in a fibrocollagenous stroma, it was put into a separate entity in 1975. Extensive search of the literature yielded only about 50 cases reported till date. Patients have an excellent outcome as complete cure is achieved after total enucleation and thorough curettage. The significance of detecting such a lesion lies in the fact that it must be clinically, radiologically and histomorphologically distinguished from lesions like acanthomaous ameloblastoma and intraosseous squamous cell carcinoma which have worse prognosis than SOTs. . We report a case of SOT in a 45 year old male in maxilla which was clinically diagnosed as ameloblastoma.
