Background :
@EN Keloids may occur at any age, but tend to develop between the ages of 10 and 30. The incidence and median age of onset are equal for both sexes. Keloids are common among the darker pigmented races, but there have been a few clinical studies
of
keloids in Korea. Objective : The purpose of this study was to evaluate the variable clinical characteristics of keloids in Korea.
@ES Methods :
@EN This clinical investigation was made with 223 outpatients of keloid who had visited the department of Dermatology, Chonnam University Hospital from January 1984 to December 1993.
@ES Results :
@EN 1. The annual incidence averaged over 10 years was 0.83%(36 cases of total 43,752 outpatients).
2. The ratio of male male to female was 1 : 0.94(Male : 115, Female :108).
3. The mean age of the onset and at the first visit to our hospital were 24.5years and 29.2 years,respectively.
4. In our series the presternal area was the most common sites, the shouder region next. Most keloids on the shoulder were related to BCG vaccination in infancy or chilhood.
5. The precipitating fa ctors associated with keloid were preceeding dermatologic diseases(33.2%), unknown(17.9%), injection & vaccination (15.2%), operation (13.9%), burn(13.9%) and laceration (5.8%) in descending order.
6. Among preceeding associated dermatologic diseases, acne was the most common.
7. A positive family history is more likely in cases of multiple keloidal (p<0.001), and severe keloidal formation.
8. Most patients did not complain of any symptoms(45.3%) and a symptom of pain or tenderness(40.8%) was present rather than pruritus (13.9%).
9. The most prevalent treatment modality was intralesional injection with triamcinolone acetonide (84.3%).
@ES Conclusion :
@EN According to this study, usually keloids occured in patients between 10 and 29 years of age, and most keloids were located on the antetior portion of the chest, shoulders, and face and scalp. A positive family history is more likely in cases
of
multiple, severe keloidal for mation. (Kor J Dermatol 1995;33(3) : 489~496)
