International Journal of Case Reports and Images (IJCRI) is an international, peer reviewed, monthly, open access, online journal, publishing high-quality, articles in all areas of basic medical sciences and clinical specialties.Aim of IJCRI is to encourage the publication of new information by providing a platform for reporting of unique, unusual and rare cases which enhance understanding of disease process, its diagnosis, management and clinico-pathologic correlations. We hereby report, not previously reported a characteristic case of an odontogenic keratocyst related to the anterior maxillary teeth in a teenage female of 13 years. On histological examination of the biopsy, frank invasion was seen and a diagnosis of squamous cell carcinoma on top of keratocyst was given. IJCRI publishes Review Conclusion:The diagnosis was predicted on recognition of the histopathologic features of odontogenic keratocyst associated with dysplastic features of the epithelial lining and areas of invasion in other parts; the clinical symptoms are modest, only presenting a palatal swelling.

Schneiderian papillomas (SPs) are benign tumors found in the Sino-nasal tract. They present tendency to recur and have been reported to be associated with malignancy in approximately 4-17% of the cases.We hereby report a case of SP showing dysplastic changes rendering it premalignant.In the present case resection of the tumor was done after an endoscopic in scional biopsy was taken earlier and was diagnosed as Schneiderian papilloma with malignant foci.The present report might improve the understanding of the sino-nasal papillomas and consider putting them in the differential diagnosis of maxillary sinus tumors of aggressive behavior which may extend intra-orally and reach the roots of the teeth.
