Abstract:
BACKGROUND: The incidence of skin diseases in the university hospital may not truely indicate their province in the population, nevertheless it offers the only available source of information.Objective and Method: To study the prevalence of common dermatoses and compare this with previous reports, we reviewed 20, 000 new outpatients who visited the Department of Dermatology at Wonju Christian Hospital from 2000 to 2004, and have statistically analyzed the findings. RESULTS: The study results are summarized as follows: 1. Of the 20, 000 outpatients, the total number of male patients was 9, 871 (49.4%), and the numbers of female patients was 10, 129 (50.6%). 2. As for age distribution, the most frequent age group was the first decade (15.3%), fifth decade (15.1%), fourth decade (13.9%) and sixth decade (13.7%), comprising 58% of the total outpatients. 3. The 19 most common dermatoses were found to be dermatophytosis, atopic dermatitis, allergic contact dermatitis, other eczema, urticaria, alopecia, herpes zoster, seborrheic dermatitis, psoriasis, bacterial infection, pruritus, drug eruption, vitiligo, acne, verruca, irritant contact dermatitis, benign epidermal tumors, nevocellular nevus and hyperpigmentary disorders. 4. Those dermatoses which showed a decreasing tendency to be treated by medicine included allergic contact dermatitis, other eczema, bacterial infections, acne, and irritant contact dermatitis. An increasing tendency was noted in dermatophytosis, urticaria, alopecia, herpes zoster, seborrheic dermatitis, psoriasis, pruritus, drug eruption, vitiligo, verruca, benign epidermal tumors and nevocellular nevus. There was no significant annual difference in incidences of hyperpigmentory disorders compared to atopic dermatitis. 5. Diseases with high seasonal distribution in summer were dermatophytosis and verruca. However, atopic dermatitis, alopecia, herpes zoster and pruritus showed high incidence in the winter period. Acne showed a peak incidence in both summer and winter. 6. As for gender distribution, dermatophytosis, alopecia, seborrheic dermatitis, bacterial infection and vitiligo showed a high frequency in males, whereas allergic contact dermatitis, urticaria, herpes zoster, psoriasis, pruritus, drug eruption, acne, epidermal benign tumors, nevocellular nevus and hyperpigmentary disorders showed a high freguency in female. 7. In age distribution, atopic dermatitis, bacterial infection, vitiligo, verruca and nevocellular nevus were found to be the most frequent in the first decade, and acne and alopecia in the second decade. Urticaria and psoriasis were most frequent in the third decade; dermatophytoses, allergic contact dermatitis, irritant contact dermatitis and hyperpigmentary disorders in the fifth decade; other eczema, seborrheic dermatitis and pruritus in the sixth decade; herpes zoster and drug eruption in the seventh decade; and epidermal benign tumors in the eighth decade. 8. In the distribution of dermatoses as disease groups, eczema (25.5%), diseases of the skin appendages (10.8%), dermatophytosis (10.0%), erythema, urticaria and drug eruption(10.2%), viral infections (8.4%), papulosquamous disease (4.1%), and pruritus and neurocutaneous disease (3.9%) constituted 72.5% of the total. CONCLUSION: The distribution of skin disease in our hospital was similar to studies wnducted in other provinces. Comparing the alone results with earlier studies carried out in the same area by Lee (3), Won (2) and Song (1), there was a relatively low incidence of dermatoses caused by animal parasites. However, a predominently high incidence of age related dermatoses was found.
