Melanocytic nevi are a benign clonal proliferation of cells expressing the melanocytic phenotype, with heterogeneous clinical and molecular characteristics. In this review, we discuss the genetics of nevi by salient nevi subtypes: congenital melanocytic nevi, acquired melanocytic nevi, blue nevi, and Spitz nevi. While the molecular etiology of nevi has been less thoroughly studied than melanoma, it is clear that nevi and melanoma share common driver mutations. Acquired melanocytic nevi harbor on

BACKGROUND: Infraorbital dark circles refer to the conditions that present with darkness of the infraorbital eyelids. Although it is not a medical concern, it can be a cosmetic concern for a large number of individuals. Moreover, clear definition and possible causes have not been elucidated. OBJECTIVE: To review the possible causes and treatment options for infraorbital dark circles. METHODS: The article is based on a review of the medical literature and the author's clinical experience in treat

BACKGROUND: Many endogenous and exogenous factors are known to cause enlarged pilosebaceous pores. Such factors include sex, genetic predisposition, ageing, chronic ultraviolet light exposure, comedogenic xenobiotics, acne and seborrhoea. This study was an attempt to determine the factors related to enlarged pores. OBJECTIVES: To assess the relationship of sebum output, age, sex, hormonal factors and severity of acne with pore size. METHODS: A prospective, randomized, controlled study was design

PURPOSE: A retrospective study was conducted to review the treatment and outcomes of mainly melanomas in acral location in a single institution in Korea, and to evaluate the prognostic significance of anatomic locations of the tumor. MATERIALS AND METHODS: A retrospective review was completed on 40 patients between 2001 and 2006 to obtain pertinent demographic data, tumor data, treatment characteristics, and follow-up data. RESULTS: Forty melanoma patients were identified and analyzed. Of these,

BACKGROUND: Numerous modalities have been used to treat vitiligo in children. Up to now, phototherapy and topical corticosteroids are the most commonly used treatments for adult vitiligo but studies evaluating the efficacy of these treatments in the pediatric population remain insufficient. OBJECTIVE: This study was a retrospective review to evaluate the efficacy and safety of 308-nm excimer laser treatment in 30 childhood vitiligo patients. METHODS: Thirty vitiligo patients with 40 vitiligo pat

BACKGROUND: Infraorbital dark circles are a cosmetic concern for a large number of individuals. However, the exact definition and precise cause has not been elucidated clearly. In our experience infraorbital dark circles due to thin and translucent lower eyelid skin overlying the orbicularis oculi muscle can be treated successfully with autologous fat transplantation. OBJECTIVES: This study was conducted to clarify the nature of dark circles under the eyes and determine the efficacy of autologou

The published findings on gender disparities in melanoma have yielded many advances in our understanding of this disease. Biological, environmental, and behavioral factors may explain the observed gender difference in melanoma incidence and outcome. Further research will enable us to learn more about melanoma pathogenesis, with the goal of offering better treatments and preventative advice to our patients.

Autologous fat transplantation is an effective method for long-term correction of depressed atrophic scars left by linear scleroderma on the forehead but is less effective for corrections on the nose, infraorbital area, and chin.

Postoperative neck scarring is a major concern for patients who undergo thyroid surgery; however, the treatments for hypertrophic scars are generally considered by patients to provide unsatisfactory outcomes. Therefore, risk factors should be identified and prevention of these factors is considered to be critical in management. We reviewed the medical records of 96 thyroidectomy patients who were divided into two groups based on scar type: patients with hypertrophic (n = 61) and linear flat scar

BACKGROUND: Dermatofibrosarcoma protuberans (DFSP) is a rare soft-tissue tumour with a high local recurrence rate. Recent reports indicate more favourable cure rates with Mohs' micrographic surgery (MMS). AIM: To investigate the beneficial use of MMS for DFSP in a single institution in Korea. METHODS: A retrospective review was performed of pertinent demographic data, tumour data, treatment characteristics and follow-up data of 11 patients between 1997 and 2007. A review of literature for treatm

Purpose: A retrospective study was conducted to review the treatment and outcomes of mainly melanomas in acral location in a single institution in Korea, and to evaluate the prognostic significance of anatomic locations of the tumor. Materials and Methods: A retrospective review was completed on 40 patients between 2001 and 2006 to obtain pertinent demographic data, tumor data, treatment characteristics,and follow-up data.

Acral melanoma commonly occurs in areas that are not exposed to much sunlight, such as the sole of the foot. Little is known about risk factors and mutational processes of plantar acral melanoma. Nuclear envelope rupture during interphase contributes to genome instability in cancer. Here, we show that the nuclear and micronuclear membranes of melanoma cells are frequently ruptured by macroscopic mechanical stress on the plantar surface due to weight-bearing activities. The marginal region of pla

Treatment with a 1064 nm Nd:YAG laser is an effective method for reducing pore size and sebum level.
