Abstract
- BACKGROUND
Skin diseases on the auricle are common and can sometimes cause severe functional and morphological problems.
OBJECTIVE
This study was conducted to investigate the epidemiological aspects of auricular skin diseases and to emphasize common skin diseases according to each part of the auricle.
METHODS
We retrospectively reviewed the data of 301 patients with auricular skin disease, who had visited Pusan National University Hospital between January 1999 and December 2009.
RESULTS
The most frequent auricular skin diseases were basal cell carcinoma, keloid, psoriasis, epidermal cysts, allergic contact dermatitis, atopic dermatitis, and vitiligo, in decreasing order of frequency. Of 174 patients with generalized skin lesions involving the auricles, the common skin diseases were psoriasis, atopic dermatitis, and allergic contact dermatitis. Of 22 patients whose skin diseases were involved in both auricles without generalized lesions, keloid was the most common skin disease. Of 105 patients with skin diseases involving only one auricle, the common skin diseases were basal cell carcinoma, keloid, and seborrheic keratosis. In patients with unilaterally auricle-localized skin lesions, the most common skin diseases according to each part of the auricle were as follows: helix and ear lobe, keloid; concha, seborrheic keratosis; tragus, melanocytic nevus; and preauricular and postauricular area, basal cell carcinoma.
CONCLUSION
The frequency of auricular skin diseases was different according to each part of the auricle. Thus, it would be helpful for dermatologists to be aware of common skin diseases in each part of the auricle.
