The studies were undertaken on 47 cases of white epithelium which were diagnosed during 1206 routine colposcopic examination.
The results summarized were as follows.
White epithelium, 47 cases among 1206 colposcopic examination revealed an incidence of 3.89%.
In the age distribution of white epithelium both 30-34 and 40-44 age groups showed 23.4% were the highest respectively.
Cytologic classification of white epithelium was normal in 55.3 %, suspicious
27.7 % and positive 17.0%.
Biopsy results of white epithelium were dysplasia revealed 61.9%, the highest value, ca. in situ 19.0%, invasive ca. 14.3% and non made 4.8% respectively.
Cases of white epithelium superimposed by punctation, mosaic and mosaic and punctation were 12.8, 10.6% and 14.9% respectively, whereas group of white epithelium only was 61.7%.
On the locations of white epithetium group of surrounding the ext. os revealed the largest number and cases of confined to upper lip 19.2 %, both lips 12.7 % and lower lip 10. 6% in order.
White epithelium creeping into the cervical canal were only 3 cases.
The comparative study on cytology more than class if between group of surrounding ext. os and group of remainders was totaled 48.2 % and 38.9 %, therefore revealed no substantial difference.
