Background: Psoriasis is a chronic relapsing disorder
which is influenced by various external factors. Korean
psoriasis vulgaris are characterized by smaller sized
plaques than those of Western population and this type
of psoriasis was reported to be small plaque(SP)
psoriasis. However there are also some Korean psoriasis
patients with large plaque(LP) type similar to Western
psoriasis patients, although the numbers are less than SP
psoriasis. Therefore Korean psoriasis patients were able
to be divided into the LP type and the SP type according
to the size of the plaque. It is necessary to investigate the
correlations between risk factors and these two clinical
types of psoriasis vulgaris.
Objective: The purpose of this study is to investigate
external factors differentially correlated with LP and SP
psoriasis vulgaris.
Methods: A retrospective analysis was conducted with
106 psoriasis patients seen between 2003 and 2004 in
Youngdong Severance Hospital. Psoriasis vulgaris was
classified according to the size of the plaque.
Results: 55.6% of the SP psoriasis patients experienced
aggravation with alcohol intake while 84% of
the LP psoriasis patients did. Among the external factors
investigated, only alcohol intake as an aggravating factor
showed statistically significant difference between SP and
LP psoriasis.
Conclusion: Our results suggest that susceptibility
to aggravation by alcohol seems to be associated with
phenotypic appearance of lesion size in psoriasis
