Oral Potentially Malignant Disorders - Did you know?
Certain red/white/red-white lesions of the oral cavity have a potential or a higher risk to develop malignancy (oral squamous cell carcinoma). Such lesions are called “Oral potentially malignant disorders (OPMD)”.
The term “dysplasia” denotes the abnormal development of a tissue and “epithelial dysplasia (ED)” is used to designate the atypical characteristics of the epithelium (indicating malignant risk) under the microscope.
🤨 Did you know Oral Precancerous lesions and conditions are better termed Oral Potentially Malignant Disorders?
These diseases (epithelial pathologies, be it lesions or conditions) that could undergo malignant transformation are no more classified as precancerous lesions or conditions. Earlier (1978), WHO termed such disorders as oral precancers and classified them as precancerous lesions and precancerous conditions.
Morphologically altered tissue in which oral cancer is more likely to occur than in its apparently normal counterpart.
A generalized state associated with a significantly increased risk of cancer.
🤨Oral Potentially Malignant Disorders
In 2005, Oral medicine and Oral pathology experts in a workshop organized by WHO Collaborating Centre for Oral Cancer and Precancer in the UK, proposed the term Oral potentially malignant disorders for defining all oral precancers (lesions and conditions).
Hence all mucosal diseases having a potential to become OSCC are collectively called Oral potentially malignant disorders.
