Background: Rosacea is a chronic inflammatory skin disorder characterized by erythema, papules, ocular symptoms, and heightened sensitivity. Patients with neurogenic symptoms such as burning or stinging remain particularly difficult to manage. Current guidelines often underrepresent energy-based devices (EBDs), pigmentary sequelae, psychosocial burden, and ocular comorbidities. Objective: To examine Korean dermatologists’ expert perspectives on rosacea management, focusing on skin sensitivity, neurogenic symptoms, pigmentary changes, psychosocial impact, ocular involvement, and EBD use. Methods: A web-based, 29-item survey was administered to 25 board-certified Korean dermatologists (May–June 2025). Quantitative and qualitative responses were analyzed. Results: Erythematotelangiectatic and papulopustular phenotypes with sensitivity skin predominated. EBDs (pulsed dye laser, intense pulsed light) were frequently used but limited by cost and sensitivity issues. Neurogenic symptoms were recognized but rarely treated with neuromodulators. Post-inflammatory hyperpigmentation was infrequent, yet monitoring was inconsistent.Psychosocial and ocular aspects were acknowledged but seldomly systematically addressed.Respondents expressed interest in emerging adjunctive treatments such as cold plasma, skin boosters, and holistic care approaches. Conclusion Korean dermatologists adopt individualized strategies for rosacea, yet practice gaps remain regarding neurogenic symptoms, pigmentary complications, and psychosocial and ocular comorbidities. Findings support the need for updated multidisciplinary, phenotype-driven guidelines aligned with real-world practice.

This report describes two cases of patients with rosacea treated with a polycaprolactone (PCL)-based topical formulation combined with nonablative cold atmospheric plasma (CAP). Both patients, two Korean females aged 32 and 47 years, exhibited substantial improvement in their symptoms following the combined therapy.The CAP-assisted topical PCL emulsion therapy effectively diminished facial erythema, telangiectasia, and the inflammatory papules of rosacea without any significant adverse events. The report suggests that this novel therapeutic approach may represent a promising alternative to laser therapy for managing rosacea, under scoring the need for further research to elucidate its long-term efficacy and safety.

Background: With the increasing demand for surgical procedures in dermatology, resident education in surgical dermatology has become important for delivering high-quality treatment.However, it remains unclear if a sufficient number of residency programs with quality standards exist, as there has been little research on this subject in South Korea. Objective: To identify the status of surgical dermatology education among residents and assess dermatologists’ perceptions of the subject. Methods: A 35-question survey was developed and distributed to all resident training hospitals and local clinics listed by the Korean Society of Dermatologic Surgery. Only third- and fourthyear residents were included and board-certified specialists from training hospitals and local clinics responded to the surveys. Results: Survey participants included 88 residents and 120 specialists of whom one-quarter of the residents attended regular monthly educational sessions. Most residents (93%) participated in cosmetic procedures, and many performed laser therapy. However, the opportunity for toxin or filler injection was rare, with only 12% of the residents having experience with filler injections. In response, 49% of residents and 32% of specialists said that more cosmetic training was required, whereas 28% of residents and 50% of specialists said that more training for both cosmetic and conventional surgeries was necessary. Conclusion The survey demonstrated a need for more training programs in surgical dermatology during residency and a perception gap between residents and specialists. Therefore, developing educational residency programs that focus on basic dermatologic surgery principles and their applications in cosmetic procedures is essential.

Barraquer-Simons syndrome is a rare acquired lipodystrophy characterized by gradually symmetric subcutaneous fat loss in a craniocaudal distribution, often associated with hypocomplementemia and nephropathies. Facial cosmetic treatment in this disorder has not been fully described in the literature. We present a patient with Barraquer-Simons syndrome with emphasis on early cosmetic intervention with autologous fat grafting and its long-term efficacy. At the follow-up 37 months after the last fat grafting, preservation of the grafted fat was noted while lipodystrophy progressed in the trunk regions. Autologous fat grafting is suggested for the correction of facial dysmorphism in this type of lipodystrophy.

BACKGROUND: Paronychia is a common infectious disease affecting fingernails and toenails. Although bacterial and fungal infections as well as mechanical trauma may play roles in the pathogenesis of this disease, there are few bacteriological studies about paronychia in military personnel. OBJECTIVE: To identify the causative bacteria of paronychia in military personnel. METHODS: We retrospectively analyzed the microbiological results of 145 patients who visited a tertiary referral hospital for Korean soldiers from August 2004 to October 2006. RESULTS: Twenty-eight different types of aerobic bacteria were identified, with the most common being Staphylococcus aureus (38.0%), Streptococcus pyogenes (7.2%), and Pseudomonas aeruginosa (5.4%). Staphylococcus aureus was identified mostly in finger and toe paronychial lesions and Pseudomonas aeruginosa was recovered commonly from toe paronychial lesions. All cases of paronychia were controlled by the combination of antiseptic dressing, topical antibacterial ointment, oral antibiotics, and antimycotic agents. CONCLUSION: The types of bacteria that most commonly caused paronychia in military personnel were Staphylococcus aureus, Staphylococcus pyogenes, and Pseudomonas aeruginosa. Thus, the commonly used oral antibiotics for paronychia, such as amoxicillin-clavulanate, clindamycin, and trimethoprim-sulfamethoxazole, are good choices in the treatment of paronychia in military personnel.

BACKGROUND: The utilization of botulinum toxin has rapidly expanded into various aesthetic applications. Achieving success with the aesthetic use of neurotoxins depends on several factors, including an understanding of the anatomy, the methods of dilution and the injection technique. Any guidelines representing a consensus for aesthetic treatments using botulinum toxin type A (BTA) have not been published in Korea. OBJECTIVE: We wanted to provide consensus recommendations on the treatment of facial wrinkles and benign masseter hypertrophy using BTA in Korean patients. METHODS: A panel of experienced Korean dermatologists was convened to develop a clinical consensus. The clinical consensus was comprised of the recommendations of the panel and the guidelines on general issues, such as the reconstitution and handling of the BTA, the procedural considerations, the dosing and injection-site standardizations, and the prevention and treatment of unwanted effects. Specific recommendations were provided according to the area of treatment, including glabellar lines, horizontal forehead lines, lateral periorbital wrinkles and benign masseter hypertrophy. RESULTS: The recommended final concentration of BTA was 50 units/ml (5 units/0.1 ml) after reconstitution with physiologic saline. For glabellar lines, the members recommend three injection points (a total of 8 units). For forehead wrinkles, the members recommend nine injections in two rows into the frontalis with 1 unit/point. For crow's feet, the members recommend three injections per side (7 units/side) at the lateral part of the orbicularis oculi. For benign masseter hypertrophy, three injections per side (24~30 units/side) were recommended. CONCLUSION: These consensus recommendations will provide a framework for Korean dermatologists who wish to perform safe and efficacious injection of BTA for facial rejuvenation.

The term muscle herniation represents focal muscular protrusions through an acquired or congenital fascial defect. The anterior tibialis muscle is the most common site of herniation. Dynamic ultrasonography has become an important tool in dermatology for diagnosing suspected muscle herniation because it is a non-invasive, highly accurate, readily available and cost-effective imaging technique. We present here the case of a 21-year-old male Korean soldier who underwent dynamic ultrasonography to confirm the diagnosis of anterior tibialis muscle herniation.

BACKGROUND: Persistent facial telangiectasia, erythema and flushing are the major cosmetic problems in patients with rosacea. However various therapeutic treatments for rosacea papules and pustules are not effective in reducing telangiectasia and flushing reactions. Matrix-centered theory that dermal matrix degradation can cause telangiectasis, erythema and flushing, is one of the various theories of rosacea pathogenesis. Shark cartilage extracts are collagenase inhibitors and can inhibit dermal matrix degradation. OBJECTIVE: The purpose of this study was to evaluate the clinical effects of shark catilage extracts (Venatrix(R)) for erythematotelangiectatic rosacea patients. METHODS: Twenty three patients with erythematotelangiectatic rosacea applied shark cartilage extracts twice daily for up to 8 weeks. Efficacy was evaluated by erythema index using mexameter (MPA 5, CK, Germany) and clinical photography. RESULTS: Erythema index decreased from 525.7+/-114 to 413.9+/-101.7 (mean reduction: 21.3%) (p<0.1) after 8 weeks treatment. 16 patients (69%) showed excellent or good results by clinical photography. Transient stinging sensation was the most common adverse effect and these symptoms improved after the first few days. There were no other significant side effects. CONCLUSION: Shark cartilage extracts may be an effective treatment for mild erythematotelangiectatic rosacea.

BACKGROUND: Chilblain or pernio is a cold-induced, inflammatory skin problem which occurs usually on acral areas bilaterally. Because chilblain commonly develops in cold, damp climates, many soldiers may experience occupational chilblain during military service in Korea. OBJECTIVE: The purpose of this study is to analyze the clinical characteristics of chilblain in Korean soldiers. METHODS: We reviewed the clinical findings in 199 patients with chilblain who visited the department of dermatology, Armed Forces Capital Hospital during the 5-year period from 2002 to 2007. We investigated the epidemiology, aggravation factors, duration of the disease, clinical manifestations and treatment. RESULTS: The results were as follows; The average age was 21.51+/-1.86 years old. The chilblain usually developed during winter and the duration of symptoms ranged from 1 day to 4 years. All patients developed skin lesions on acral areas. Erythematous skin lesions were observed in 133 patients and purpuric lesions were seen in 56 patients. The lesions were symmetrical in 171 patients 43 patients had history of recurrence. Treatment includes nifedipine and pentoxyfilline. The supportive treatment includes rest and keeping warm, topical corticosteroids or antibiotics and oral antihistamine, analgesics, or antibiotics. CONCLUSION: This investigation is expected to help understand and obtain more information on chilblain.

Herpes simplex virus (Herpesvirus hominis), a member of the herpeptoviridae family, is among the most common infectious viral pathogens in humans. Types of HSV can be subdivided into HSV-1 and HSV-2 on the basis of physiological, serologic and epidemiologic differences, although both are closely related immunologically and DNA sequence homology. HSV-1 is frequently associated with oropharyngeal, eye and skin infections, while HSV-2 is most commonly associated with genital tract infections. Characteristically after the primary infection, HSV can be linked to latency in neural tissue. Reactivation of HSV can be triggered by sunburn, fever, stress, menstruation and local trauma. Here we report a case of reactivation of herpes simplex virus type 2 in foot dorsum followed by repetitive friction due to Sandals' trap.
