“…Clinical descriptions of oral lupus lesions vary enormously in the different studies, and the terminology used to describe oral lesions in the scientific literature in patients with lupus is somewhat imprecise and varied, highlighting the following: 'lupus cheilitis', 'chronic plaques', 'oral discoid lesions', 'honeycomb plaques', 'lichen planus-like lesions', 'keratotic lesions', 'ulcerative plaques', 'oral ulcers', 'erythematous patches', 'pebbly red areas', 'purpuric lesions', enanthema and 'diffuse palatal petechial erythema'. 4,9,10,12,13,17,18,[20][21][22][24][25][26][27][28][29][30][31][32][33] Thus, in contrast to cutaneous lupus lesions, no uniformity exists in classifying oral lesions. An adequate clinical categorization is lacking, and as a consequence, a comparison between existing studies is hampered.…”
