Nerve sheath myxoma of the oral cavity: a distinct entity

AbstractNerve sheath myxomas (NSM) are uncommon benign tumours of nerve sheath origin. These tumours are most often located in the dermis and subcutaneous tissue of the head and neck region, but less frequently can also involve extracutaneous sites but they are rarely seen in the oral cavity. Many authors consider nerve sheath myxoma and neurothekeoma to be variants of the same tumour, though currently it has been demonstrated that both the lesions are distinct entities with different origins and unique morphological features. Herein we report a case of Nerve Sheath Myxoma on the palatal gingiva.
