( Ga Ram Ahn ),( Ji Yeon Hong ),( Seong Jun Seo ),( Myeung Nam Kim ),( Chang Kwun Hong ) 대한피부과학회 2016 대한피부과학회 학술발표대회집 Vol.68 No.1
Acute diffuse and total alopecia (ADTA) is a recently established subtype of alopecia areata (AA). Typically, ADTA, showing marked female predominance, initially develops without remarkable alopecic patch, progresses rapidly involving over than 80% of scalp area and resolves within 6 months. A 37-year-old female patient presented with diffuse hair loss on the scalp since 3 months ago. Histopathological examination revealed moderate peribulbar eosinophilic inflammation around the follicles. She showed remarkable improvement after being treated with systemic steroid, 308-nm excimer laser and intralesional injection. ADTA can be misdiagnosed initially as alopecia totalis (AT) since their similar clinical aspect of diffuse hair loss. However, ADTA can be distinguished from AT by its better prognosis and perifollicular eosinophilic infiltration. Herein, we reported a case of ADTA with favorable prognosis and typical histopathological feature.

Clear cell acanthoma (CCA) is an uncommon, benign epithelial tumor presenting as a well-defined, slow-growing solitary nodule. The diagnosis of CCA is usually based on clinical and histopathological evaluation of the tumor. However, when such type of benign tumor occurs on an exposed area, a biopsy is not always the best diagnostic option since it may leave scar. The recent advent of dermoscopy has offered an accurate and non-invasive method to diagnose CCA without resorting to skin biopsy. A 40-year-old male presented with a shiny, erythematous-to-brown, flattened nodule on the left cheek. Dermoscopic examination revealed a ‘string of pearls’ vascular pattern, a characteristic dermoscopic feature of CCA. Under the clinical and dermoscopic impression of CCA, a 595 nm pulsed dye laser (PDL) therapy targeting the vascular tissue in the superficial dermis of the lesion was chosen for a minimally invasive treatment. After repeated sessions of PDL, an optimal cosmetic outcome was achieved and no recurrence was recorded during the follow-up period. Herein, we report a case of presumed CCA which was successfully diagnosed and treated by utilizing non-invasive modalities. (Ann Dermatol 33(3) 275∼277, 2021)

Lipoma is a common benign adipose tumor which usually appears as painless, round and mobile mass. Surgical excision is considered as the treatment of choice for lipoma. However, some patients are reluctant to undergo an operation due to the risk of scarring especially when the lesion occurred on the exposed area such as face. A radiofrequency (RF) microneedle device can create a thermal coagulation zone at a controlled depth around the needle tip without unwanted epidermal damage. A 54-year-old healthy male presented with a painless slow-growing mass on his right cheek. Ultrasonography revealed an oval compressible hyperechoic mass with a fat density. Under the clinical and ultrasonographic impression of lipoma, monopolar RF device with insulated microneedle was chosen for a minimally invasive treatment. After the repeated sessions of treatment, the volume of the affected cheek was dramatically diminished and the patient was very satisfied with the outcome. In this study, we report size reduction and cosmetic improvements in a large facial lipoma treated with a novel RF microneedle device.

As the popularity of dermal fillers has grown rapidly in recent years, the number of complications has been also increased. Among them, vascular compromise following filler injection is a major, emergent complication causing an embolism or external compression that impedes blood flow. Since various dermal fillers are recognizable with ultrasound, presenting different patterns of echogenicity and posterior acoustic artefacts, ultrasonography is regarded as an ideal diagnostic instrument to evaluate filler complications. A 42-year-old female presented to with discoloration, pain on her right cheek occurred after hyaluronic acid (HA) filler injection on right nasolabial fold. A Doppler ultrasound examination showed a hypoechoic pseudocyst compressing the near vessel. Under guidance with ultrasound, hyaluronidase was immediately injected into the pseudocyst. Following additional treatment including sublingual nitroglycerin and low-dose aspirin administration, saline soaking, topical antibiotics, hyperbaric oxygen therapy, 833-nm LED irradiation, and occlusive dressing, the skin lesions were completely resolved without any scarring or defect. Herein, we report a case of vascular filler complication which emphasizes the usefulness of Doppler ultrasound for proper evaluation and management., r,

Purpose: This study aimed to examine exercise program on health related physical fitness, self-efficacy and physical activity level in adults with intellectual disability. Method: A pre-post test experimental research design with a control group was used. 12 Adults with intellectual disability were recruited for the exercise group and 11 for the control group separately. The measures of health related physical fitness included cardio pulmonary endurance (step-test), body composition (Bioelectrical impedance analysis), flexibility (sit and reach), muscle endurance (sit-up) and strength (hand grip strength). Self-efficacy was measured using the Physical Self-Efficacy (PSE) scale. Accelerometer was used to measure physical activity level. All variables were measured twice at baseline and at the completion of the exercise program. Exercise program using band exercise and rhythmic activity involved 90 minute session, two times per week for 12 weeks. Result: After the intervention, significant improvements were found in muscle endurance of health related physical fitness measure, self-efficacy, physical activity level in the experimental group. Conclusion: Exercise program may be recommended as a method to maintain and promote the health of adult with intellectual disability.

Thus, early diagnosis and treatment of atopic dermatitis are important, and understanding of its genetic basis is needed to facilitate early detection. The polymorphisms of COL6A6 are family-specific candidate variants of early-onset AD detected by whole exome sequencing in previous study. Objectives: Our present study validated the association between early-onset AD and COL6A6 variation in Korean population-based case-control study. Methods: 110 AD patients and 62 control subjects under 3years old were enrolled in the study. Three variants (rs16830494 in exon 30, rs59021909 in exon 4 and rs200963433 in exon 6) of COL6A6 were sequenced by Sanger sequencing. Three variants were also compared with serum levels of total IgE and blood eosinophil count. Results: We were able to detect a rare variant (rs200963433) exclusively in AD patients. The frequency of a minor allele (T) rs59021909 was increased in the AD group, and rs59021909 also influences lower serum IgE levels. Conclusion: Our study suggests the possibility that COL6A6 variants are significantly associated with risk of early-onset atopic dermatitis. This study will provide a genetic basis for diagnosis and the development of new therapies for early-onset atopic dermatitis in Koreans. Functional studies are necessary to discover variant function.

Background: Conventional treatment options for periorbital syringomas are often unsatisfactory because of inevitable surface damages from the procedure and frequent recurrence rate of the tumors. Objectives: This study aimed to investigate the efficacy and safety of intralesional electrosurgery using a monopolar radiofrequency device with a single insulated microneedle for the treatment of periorbital syringomas. Methods: A retrospective analysis was performed using data from medical records, routine questionnaires, and clinical photographs of 55 patients with periorbital syringoma, who underwent intralesional electrosurgery. Results: Approximately half of the patients (50.9%) experienced marked resolution after one treatment. The lesion clearance rate increased and lesion severity decreased each time the treatment was repeated. No persistent therapy-related adverse event was found except transient erythema or crusting. Conclusion: Intralesional electrosurgery with insulated microneedle is an effective and safe treatment option for periorbital syringomas.
