While interest in steroids use has increased rapidly, people have also been acquiring misinformation causing rampant fears about steroid use. Objectives: To identify the fear and misunderstanding regarding the use of steroids by comparing the attitudes of doctors, treatment experience group, and non-experience group towards steroid use. Methods: Questionnaire surveys were conducted on a 346 participants which consisted of outpatients of the Department of Dermatology at Hallym University Sacred Heart Hospital, physicians at our hospital, and people who visited the Department of Occupational and Environmental Medicine at our hospital. Results: The topical treatment group had a high response rate of 46.7% for being “somewhat anxious” about using topical steroids, while the oral treatment group had a high response rate of 53.8% for being “somewhat anxious” about using oral steroids. With respect to information on adverse effects of using steroids, those in the non-experience group obtained their information mostly from the Internet(67.5%) and the media(47.5%), whereas those in the topical treatment group obtained information from product guides(48%) and doctors(38.7%). Conclusion: Dermatologists need to evaluate the validity of information that patients have about adverse effects of topical and oral steroid use, and phenomenon of steroid phobia that results from it.

Background: Dual frequency ultrasound (DFU) emerged as a new treatment modality for improving inflammatory skin disorders; however, there are a limited number of efficacy studies Objectives: This study investigated the effect of DFU on patients with refractory rosacea. Methods: We retrospectively analyzed medical records of forty two patients with refractory rosacea (erythematotelangiectatic rosacea [ETR], n = 26; papulopustular rosacea [PPR], n = 14, mixed, n=2). The patients were treated with DFU twice per week for the first week, and then once per week thereafter. Efficacy was assessed by erythema index (EI), transepithelial water loss (TEWL), and patient self-assessment (PSA). Results: Treatment with DFU resulted in significant decrease in EI, TEWL, and PSA. No significant difference was noted between in ETR and PPR. Conclusion: Application of DFU in patients with refractory rosacea resulted in improvement in persistent erythema, barrier dysfunction and patient-reported symptoms. DFU may be an additional treatment option for rosacea which is resistant to other treatments.

Background: Diphenylcyclopropenone (DPCP) immunotherapy for viral warts has been used for many years, but no studies have analyzed the treatment effects of DPCP alone, without the use of conventional therapy before immunotherapy. Objectives: We evaluated clinical efficacy of DPCP monotherapy compared to cryotherapy and pulsed dye laser therapy. We also assess the impact of initial sensitization on clinical response. Methods: We retrospectively analyzed the medical records of 250 patients with viral warts between January 2008 and December 2015. Results: DPCP-only group (n=43) showed a lower clinical response (75.6%) than cryotherapy-only (n=171, 89.8%, p<.0.01) and PDL-only group (n=36, 90.3%, p<.0.01). The positive clinical response in the successful sensitization group (n=21) was 76.3% (119/156), while 74.4% in the sensitization fail group (p=0.870). Conclusion: DPCP monotherapy has a lower clinical response than conventional therapy. Initial sensitization to DPCP does not predict a failed response with continued immunotherapy for viral wart.
[P148] A case of allergic contact dermatitis due to ciprofloxacin otic drop
( Jun Yeong Park ),( Ye Ji Jang ),( Eun Byul Cho ),( Eun Joo Park ),( Kwang Ho Kim ),( Kwang Joong Kim ) 대한피부과학회 2017 대한피부과학회 학술발표대회집 Vol.69 No.1
A 51-year-old man presented with erythematous scaly papules and patches with oozing on the right ear lobe, face, and neck for two months. He had a history of canal wall up mastoidectomy with canaloplasty due to chronic otitis media with tympanic membrane rupture about a year ago. Ciprofloxacin otic drop had been used 1 month after the surgery because of continuous otorrhea, which was considered as surgical complication. Pruritic papules and patches with oozing and crust formation spread from right ear lobe to cheek and neck after using ciprofloxacin otic drop. As patch test showed positive results for otic drop, patient was diagnosed as allergic contact dermatitis (ACD) due to ciprofloxacin ear drop. ACD caused by topical antibiotics is rare, but well documented side effect. Aminoglycoside, polypeptides, β-lactam, macrolide, benzoyl peroxide, clindamycin, mupirocin, fusidic acid are well-known antibiotic sensitizer. However, fluoroquinolone as a potent contact allergen had not been reported to our knowledge. Indeed our case presented strong positivity in patch test, which can be an obvious evidence for fluroquinolone as a potent skin sensitizer. We herein report this interesting case of ACD caused by ciprofloxacin otic drop.
A case of congenital non-neural granular cell tumor mimicking nevus lipomatosus superficialis
( Junyeong Park ),( Jiyun Jung ),( Eunbyul Cho ),( Eunjoo Park ),( Kwangho Kim ),( Kwangjoong Kim ) 대한피부과학회 2016 대한피부과학회 학술발표대회집 Vol.68 No.1
A 4-month-old infant presented with asymptomatic soft nodules on his right forearm, which had developed since birth and grown gradually. On the suspicion of nevus lipomatosus superficialis, biopsy was performed. Histopathologic findings showed monomorphic polygonal cells with abundant granular cytoplasm. Immunohistochemical stains for CD68 and vimentin were strongly positive, but were negative for S-100 protein. Based on the pathologic findings, the patient was finally diagnosed as non-neural granular cell tumor. Granular cell tumor (GCT) is benign, indolent and slow growing tumor which can be divided into conventional and non-neural GCT by immunoreactivity for S-100 protein. Non-neural granular cell tumor (NN-GCT) is typically manifested as a well-circumscribed, papulo-nodular dermal mass, and is known to occur in a younger group than does in conventional GCT, but is rare among children. To our knowledge, there have been no case reports of NN-GCT which appeared at birth and presented as grouped nodules as seen in this case. Therefore, we herein report this interesting case of congenital NN-GCT clinically mimicking NLS.
