Correct answer: D — Andreasen clinical classification

The correct answer is D. Andreasen’s clinical classification describes six forms of oral lichen planus: reticular, papular, plaque-like, atrophic, erosive and bullous. More than one form may coexist in the same patient. The original wording incorrectly called this a WHO classification and described it as a scoring system; WHO criteria are primarily diagnostic criteria for distinguishing oral lichen planus from compatible or lichenoid lesions. TNM stages malignant tumours by tumour, nodal and metastatic extent. Broders grading assesses tumour differentiation, particularly in squamous cell carcinoma. Clark levels describe the anatomical depth of melanoma invasion, while Ann Arbor staging is used for lymphoma.
