Methods:
The gender and age of 193 cases with port wine stains were compared between those with flat, those with thickening, those with thickening and nodules, in 0-19, 20-year age group. SAS6012 software package was used for Fisher's exact test and Kruskal-Wallis test.
Results:
There were 165 cases with flat (85.49%), 10 cases with thickening (5.18%), 18 cases with thickening and nodules (9.33%). Kruskal-Wallis test demonstrated significant difference between 2 age groups(P<0.01).There was an increase incidence of thickening, and thickening and nodule formation in 0-19, 20-year age group(P<0.01), but there was no gender difference between thickening and nodules.The data were analyzed by SAS6.12 Fisher's exact test and Kruskal-Wallis test.
Conclusion:
The incidence of thickening and nodule formation in PWS increase with age.
