Abstract

BACKGROUND
Data regarding the incidence rates of skin diseases that are held by general hospitals provide readily available sources of information that may be representative of the provinces they serve. The population of Goyang city has increased rapidly. Hence, a statistical study of the latest data is necessary.
OBJECTIVE
This study aimed to investigate the prevalence rates of common dermatoses in Goyang city and to compare these with previous findings.
METHODS
We reviewed the records of 21,693 outpatients who visited the Department of Dermatology at Myongji Hospital from 2009 to 2013, and we statistically analyzed the findings.
RESULTS
Of the 21,693 outpatients' records reviewed, 9,939 (45.8%) were male patients and 11,754 (54.2%) were female patients. Patients most frequently presented with dermatoses in the fourth decade of life (16.0%), followed by the first (15.2%), fifth (15.0%), and third (13.1%) decades of life, and these four age groups comprised 59.3% of the total number of outpatients. The 15 most common dermatoses were dermatophytoses, alopecia, other eczematous conditions, urticaria, herpes zoster infections, viral warts, atopic dermatitis, allergic contact dermatitis, seborrheic dermatitis, acne, irritant contact dermatitis, benign epidermal tumors, melanocytic nevi, molluscum contagiosum, and pruritus. Diseases that occurred frequently during the summer were dermatophytoses, urticaria, irritant contact dermatitis, herpes zoster infections, and molluscum contagiosum. Diseases that occurred frequently during the winter were other eczematous conditions, atopic dermatitis, and melanocytic nevi. Viral warts and acne occurred frequently in summer and winter. Seborrheic dermatitis, dermatophytoses, molluscum contagiosum, viral warts, alopecia, and benign epidermal tumors showed higher frequencies in males than in females, whereas allergic contact dermatitis, irritant contact dermatitis, herpes zoster infections, melanocytic nevi, urticaria, pruritus, acne, and other eczematous conditions showed higher frequencies in females than in males.
CONCLUSION
Compared with previous studies, the current population of Goyang city showed higher levels of herpes zoster infections and viral warts.
