Oral epithelial dysplasia: What does it really mean?
Source: www.rdhmag.com Author: Nancy W. Burkhart, RDH, EdD Patients are sometimes followed for periods of time for what is called dysplasia, leukoplakia, keratotic lesions, and previous frank carcinoma. With any degree of tissue change, the person should be followed closely and an etiology always needs to be determined. Sometimes, removal of a frictional component is suggested; at other times, the lesion may have a more ominous appearance that will alert the clinician that cancer might be high on the differential list. Obviously, in highly suspicious lesions, a biopsy would occur immediately. Patients will sometimes tell the clinician that they were previously biopsied and the report will note "evidence of dysplasia." Sometimes a diagnosis is made of dysplasia, but the lesion becomes carcinoma over time, even after the initial removal of the lesion. The reverse may be true as well, where the body responds physically and the tissue regains a state of health. Why does one individual develop carcinoma while another person may develop a mild epithelial dysplasia? Perhaps the body is able to stop progression or reverse the state of progression. These are questions that researchers continue to evaluate and study. Frictional keratosis, though, is not in the same category as dysplasia. When the frictional component is removed, the lesion will subside. An example of a common lesion that has a frictional component is cheek chewing or morsicatio buccarum. However, chronic frictional or chemical assault on the tissue over time can also cause dysplastic changes. The body has [...]
