Melanotic neuroectodermal tumor of infancy: a wolf in sheep's clothing.

Introduction: The melanotic neuroectodermal tumor of infancy (MNTI) is an exceptionally rare neoplasm. Despite their potential for local invasion, MNTI are considered benign neoplasms. Sporadic cases have been reported of MNTI acting in a malignant fashion; however, the majority of these tumors were of extragnathic origin.

Ameloblastic fibroma diagnosis, treatment and propensity for misidentification.

We present a case of a young male with a radiolucency of the posterior mandible that was diagnosed as an ameloblastic fibroma, a mixed lesion derived from odontogenic epithelium and ectomesenchyme. This case report highlights a potential pitfall of this entity that may lead to inaccurate identification and treatment. Initial frozen section analysis yielded a diagnosis of odontogenic myxoma due to histologic similarities.
