The point prevalence of atopic dermatitis (AD) among Korean adults visiting the Health Service Center for health check-ups was assessed. AD was diagnosed based on the questionnaires filled by patients and through physical examination by dermatologists. A total of 3,563 persons completed the questionnaires, and 2,032 persons were examined by the dermatologists. According to the questionnaires, the prevalence of AD was 7.1%, and from the dermatologists' examination, it was 2.6% overall, which decreased with age significantly. The prevalence in men was higher than that of women. Grading the severity of AD according to their eczema area and severity index scores, 70.6% were classified as being mild, 25.5% moderate, and 3.9% severe. Interestingly, concomitance of psoriasis and AD was found in 0.5% of those examined by the dermatologists. Our results suggest that AD is one of the most common skin diseases not only in children but also in adults in Korea.

Cutaneous metastasis from breast cancer can occur by direct invasion, lymphatic and vascular spread as well as iatrogenic implantation. Metastasis that occurs by iatrogenic implantation after needle biopsy is very rare but the potential risk must be considered. In this report, we describe a case of breast cancer cutaneous metastasis that occurred by iatrogenic implantation following core needle biopsy. A 53-year-old woman presented with a 1×1 cm sized erythematous nodule at the biopsy site after breast conserving surgery for primary cancer. Histopathological findings confirmed cutaneous metastasis. The possibility of this consequence must be considered when performing needle biopsies.
