Tumor of the maxilla-odontogenic or glandular? A diagnostic challenge and the role of immunohistochemical markers.

Today's practice in medicine has reached remarkable change mainly due to the advances in the field. Odontogenic tumors represent a spectrum of lesions ranging from hamartomas to benign and malignant neoplasms. Rarely, odontogenic tumors pose a challenge due to varied histological features. But appropriate and accurate diagnosis is crucial for further treatment and follow-up as these have an influence on the prognosis. In such situations, immunohistochemical. (IHC) markers play a significant role in the differentiating various lesions. Within its palette of histology, there are multiple histopathological presentations, many a times these features come in an intermixed pattern simulating different origin. We here, report such a case presented in a 70-year-old female came with a complaint of swelling in the posterior maxilla. The microscopic findings were indicative of a benign neoplasm. To know the nature of the lesion and arrive at a diagnosis, many IHC markers were used. Based on all these findings, a final diagnosis of unicystic ameloblastoma was arrived. [ABSTRACT FROM AUTHOR]
