Table 1. Comparison of demographic features between patients
with malignant and non-malignant lesions. Information on
s moking status (cigarettes per day and years smoking) and age in
different types of vascular classification is also provides.
Table 2. Smoking status (cigarettes per day and years smoking)
and age in different types of vascular classification.
Table 3 . Smoking status (cigarettes per day and years smoking)
and age in different types of morphological classification. The meanings
of the abbreviations are the following: fs = Flat and smooth type:
Surface: smooth; Margin: lesion without raised margins, being continuous
with the surrounding mucosa; Texture: homogeneous, regular, the lesion
with even coloration; es=elevated and smooth type: Surface: smooth;
Margin: lesion with raised margins, sharply demarcated from the
surrounding mucosa; Texture: homogeneous, regular, the lesion with even
coloration; r = Rough type.
Images 1, 2 and 3. The figures depict type I, II and
III patterns of vascularization correspondingly. In type I, the
intraepithelial papillary capillary loops are almost invisible; oblique
and arborescent vessels of small diameter can be clearly seen. In type
II, the intraepithelial papillary capillary loops are also almost
invisible, but the diameter of the clearly observed oblique and
arborescent vessels is enlarged. In type III, the mucosa is whitish and
the intraepithelial papillary capillary loops cannot be seen; if the
whitish patch is thin, the oblique and arborescent vessels may be seen
indistinctly, but if the whitish patch is thick the vessels will be
obscured.
