ABSTRACT
BACKGROUND: Although skin cancer incidence has recently increased, there has been little research into the incidence, clinical manifestations, and prognosis of skin cancers in Korea, especially in Daegu City and the Kyungpook Province. OBJECTIVE: To analyze changes over the recent two decades in incidence and clinical patterns, including recurrence of skin cancers diagnosed at a university hospital in Daegu City. METHODS: We reviewed 1,566 skin cancer cases from 1994 to 2013 at the Department of Dermatology in Kyungpook National University Hospital (KNUH). We also divided them into first (1994~2003) and second group (2004~2013) to examine changes over the years. RESULTS: The average incidence of skin cancers among the total number of outpatients was 1.39% through whole study period including 0.38% in the first and 2.10% in the second decade. Basal cell carcinoma (BCC) was the most commonly diagnosed skin cancer (total:1st:2nd=0.60%:0.16%:0.91%), followed by squamous cell carcinoma (SCC) (0.43%:0.12%:0.65%) and malignant melanoma (MM) (0.22%:0.05%:0.34%). The most common skin cancer site was the face in each decade. The recurrence of three major skin cancers (BCC, SCC and MM) was diagnosed in 49 of the 1,402 patients (3.50%). In each disease, the recurrence rate (1st:2nd) was 1.64% (BCC, 4.11%:1.34%), 3.51% (SCC, 11.11%:2.55%), and 8.57% (MM, 4.35%:9.01%). CONCLUSION: This epidemiological study provided useful information about the incidence and prognosis of skin tumors in Korea, especially in Daegu City and Kyungpook Province.

ABSTRACT
Epidermal nevi (EN) are hamartomatous lesions derived from epidermal components originating from pluripotent cell mutations. They have been categorized according to their predominant component. The existence of >2 types of EN concurrently within a single area or within contiguous areas has been rarely reported. This report describes the case of simultaneous presence of a yellowish plaque on the left medial canthus and an aggregation of closed comedo-like papules on the right side of the cheek of a 15-year-old girl.

Active sensitization of contact allergen is an uncommon complication of patch test. Para-tertiary-butylphenol (PTBP) is a component of neoprene-based adhesives used in glued leather goods such as shoes, handbags, belts and watchstraps. Contact allergy to PTBP is frequently seen when the patch test is performed. However, active sensitization to PTBP after the patch test is rare. A 23-year-old female patient came to our clinic with a brownish hyperpigmented patch on the belt position of her belly. Pruritic erythematous papules and vesicles developed on the abdomen when she wore new pants 4 months ago. Under the clinical diagnosis of allergic contact dermatitis, the patient was patch tested with the Thin-layer Rapid Use Epicutaneous Test (TRUE Test(R)). The result showed strong positive reaction to nickel sulphate and thiomersal both on day 2 and 3 after application. Twenty-nine days after the test, the patient noticed pruritus on the TRUE Test(R) area. Thirty-four days after the test, an erythematous square-shaped plaque studded with tiny vesicles developed at the PTBP patch test site. This strongly suggests that the reaction to PTBP is occurred. She was diagnosed with an active sensitization to PTBP. We report a rare and interesting case of active sensitization to PTBP after TRUE Test(R).
