Background : There has been no statistical study of dermatoses in the Suwon area and southern area of Kyonggi province which has been rapidly developing in the last 7 years.
Objective and Methods : We evaluated the recent distributions of dermatoses in the Suwon area and southern area of Kyonggi and compared them with the previous reports of other provinces of Korea. Fifty two thousand, one hundred fifty three new outpatients who visited the Ajou University Hospital from 1995 to 2001 were analysed statistically.
Results : The study results are summarized as follows : Among the 52,153 outpatients, the total number of male patients were 24,005(46.0%) and female patients were 28,148(54.0%). The frequency of age groups are as follows; the age groups were the 3rd decade(22.0%), 4th decade(20.4%), 1st decade(18.7%), 5th decade(11.5%), 2nd decade(11.1%), 6th(8.5%), 7th(5.4%), 8th and above(2.4%). The distributions of dermatoses as disease groups were eczema(28.6%), dermatophytosis(8.7%), erythema urticaria and drug eruption(8.1%), disease of skin appendages(7.9%), viral infection(7.3%), etc. Those dermatoses which demonstrated a tendency to increase annually were seborrheic dermatitis, hyperpigmentary disorders, verruca, and alopecia areata. The incidence of dermatophytosis, in particular, decreased during the study period. Seasonal distribution showed that those diseases occurring the most frequently during the summer were dermatophytosis, allergic contact dermatitis, urticaria, verruca, and vitiligo. The incidence of atopic dermatitis and nevocellular nevi increased during the winter season. Acne vulgaris was the disease occurring frequently during summer and winter. Sexual distribution of dermatoses showed that hyperpigmentary disorder, nevocellular nevi, benign epidermal tumor, acne, allergic contact dermatitis, and irritant contact dermatitis were more frequent in females, and dermatophytosis, seborrheic dermatitis, alopecia were more frequent in males. Age distribution was as follows; atopic dermatitis, vitiligo and verruca was the most frequent in the 1st decade. Acne vulgaris was the most frequent in the 2nd decade and 3rd decade. Hyperpigmentary disorder and seborrheic dermatitis were the most frequent in the 4th decade. Hyperpigmentary disorder was the most frequent in the 5th decade and herpes zoster in 6th, 7th and 8the decade and above.
Conclusion : In contrast to an earlier published report from Seoul, the infectious dermatoses, especially parasitic infestation, showed a tendency to decrease and nevocellular nevi, hyperpigmentary disorder and alopecia showed a tendency to increase. The distribution pattern of the skin disease did not differ from other provinces of Korea in general.
