Efficacy of topical agents in lichen striatus: a comparative study
( Da-ae Yu ),( Jungyoon Ohn ),( Ohsang Kwon ),( Kyu Han Kim ) 대한피부과학회 2018 대한피부과학회 학술발표대회집 Vol.70 No.2
Background: Lichen striatus is a self-limited linear inflammatory dermatosis, and topical corticosteroid or calcineurin inhibitors have been reported to be effective. Objectives: To compare the efficacy of topical agents in lichen striatus. Methods: We retrospectively reviewed medical records and clinical photos of 60 pediatric patients with lichen striatus at Seoul National University Hospital from March 2007 to December 2017. The patients were classified into three groups by topical agent; calcipotriol, calcineurin inhibitor, and corticosteroid, and follow-up duration and treatment outcome were analyzed. Results: Among a total of sixty pediatric patients, twenty seven patients (45.0%) were male. Most common anatomical locations were lower extremities (51.7%) and upper extremities (33.3%). Mean age at first visit was 3.8 years, and mean follow-up duration was 192.6 days. Good response (>75% improvement) to treatment was observed in twenty two of forty patients treated with calcipotriol (55.0%), six of thirteen patients with corticosteroid (46.2%), and three of seven treated with calcineurin inhibitor (42.9%), and there was no statistical significance. No significant adverse events were observed in all groups. Conclusion: Though there was no statistically significant difference in treatment efficacy among the topical treatment groups, topical calcipotriol showed a tendency to shorten the course of the disease. Topical calcipotriol may be a safe and effective topical agent for lichen striatus.
Blue rubber bleb nevus syndrome with facial nerve involvement: a case report
( Da-ae Yu ),( Chang-hun Huh ) 대한피부과학회 2018 대한피부과학회 학술발표대회집 Vol.70 No.1
Blue rubber bleb nevus syndrome is a rare disorder of venous malformation that affects the skin and internal viscera, such as gastrointestinal tract. Skin lesions usually appear as multiple dark blue nevi in the upper trunk and arm and may increase in size and number over lifetime. A 17 year old boy presented a bluish swelling on the left cheek since birth. Nasopharyngeal MRI showed diffused infiltrating hemangioma in the left masticator space and lower neck. Since he had no symptom other than swelling, no specific treatment was done. Twelve years later, he presented newly developed multiple bluish subcutaneous masses on his neck and anterior chest. Histopathological examination on the chest lesion showed multiple dilated vascular space lined by normal endothelium. Based on the clinical manifestations and histopathologic examination, the patient was subsequently diagnosed as blue rubber bleb nevus syndrome. He denied previous history of anemia or bleeding episodes, but had the history of objective hearing loss at regular check-up. Pure tone audiogram showed high-frequency hearing loss on the left ear. Temporal bone CT showed left facial nerve involvement of hemangioma. Esophagogastroduodenoscopy and colonoscopy revealed no vascular lesions. Herein we report a rare case of blue rubber bleb nevus syndrome with multiple skin lesions and unilateral hearing loss caused by facial nerve involvement.

Acropustulosis of infancy is characterized by recurrent, self-limited, pruritic vesiculopustular eruptions on the distal extremities in early childhood. The cause is still unclear, but its association with the scabies infection is often reported. A 2-month-old male infant presented pruritic erythematous papules and pustules with crusts on the face, palms, soles, and scrotum for one month. Skin lesions first developed on the scrotum and then spread to the palms, soles and face. The patient had no underlying disease and there was no history of scabies in his family. Previous treatment with oral antibiotics and antihistamines could not improve his symptoms. According to the clinical manifestations, the patient was subsequently diagnosed with acropustulosis of infancy. Topical corticosteroid (desoxymethasone) ointment and salicyclic acid 5% ointment were applied on his hands and foots. After one week later, he came up with much improved state of the hand and foot lesions, but with remaining crusted lesions on the face. Then, topical corticosteroid (prednisolone valerate acetate) was also applied to the face lesions and almost all lesions disappeared after one month. Herein we report a case of acropustulosis of infancy that was treated successfully with topical treatment.
Hypomelanosis of Ito with multiple congenital anomalies
( Da-ae Yu ),( Ohsang Kwon ),( Kyu Han Kim ) 대한피부과학회 2018 대한피부과학회 학술발표대회집 Vol.70 No.1
Hypomelanosis of Ito, also known as incontinentia pigmenti achromians, is a neurocutaneous disorder that is associated with chromosomal mosaicism in many cases. It is characterized by whorl-like or linear hypopigmentation along the Blaschko’s line in infancy, and other abnormalities involving the ocular, musculoskeletal, and central nervous system. A 2-month-old girl was referred to the department of dermatology for evaluation of the extending hypopigmented skin lesions developed at birth. She presented with symmetric, linear, hypopigmented patches with irregular border on the face, scalp, trunk, and both extremities. She had the history of intrauterine growth retardation as a prenatal problem. There was no specific family history and her two siblings were healthy. She also presented multiple congenital anomalies. Physical examination revealed patchy alopecia of scalp, hypoplastic nails, and irregular gingiva with saw tooth. Ocular examination showed bilateral microphthalmia, aniridia, and uncertain retinal vessels and optic nerves. Musculoskeletal examination showed syndactyly of toes, hypoplasia and clinodactly of fingers, and coccyx deviation. Chromosomal analysis showed normal karyotype, and NF-κB essential modulator (NEMO) IKBKG gene test for incontinentia pigmenti revealed no mutation. Herein, we report a rare case of hypomelanosis of Ito with multiple congenital anomalies in a patient without chromosomal mosaicism.

Background: Janus kinase (JAK) inhibitors have been considered as a promising therapy for moderate to severe alopecia areata (AA). However, there have been few comprehensive reviews on the oral JAK inhibitors for AA. Objectives: To investigate the therapeutic efficacy and adverse events of oral JAK inhibitors in AA. Methods: We performed the literature search using the MEDLINE, Embase, and the Cochrane library. A systematic review and meta-analysis was performed. The outcomes of interest were the rate of SALT50 achievement (the proportion of the AA patients who achieved more than 50% hair regrowth from baseline) and the frequency of adverse events. Results: We pooled 321 cases (263 with oral tofacitinib and 58 with oral ruxolitinib) from 12 studies. The overall rate of SALT50 achievement was 66% (95% CI 54-76%). Ruxolitinib demonstrated higher response (79% [95% CI 66%-87%]) compared to tofacitinib (62% [95% CI 49%-74%]) without statistical significance. Additional subgroup analysis by age, sex, subtype ratio, and mean duration of treatment did not demonstrate statistical significance, either. Infections were the most common adverse events, and ruxolitinib (28.0%) demonstrated less frequent adverse events compared to tofacitinib (35.2%). Conclusion: Oral JAK inhibitors, both tofacitinib and ruxolitinib were effective and tolerable for treatment of AA. Further randomized controlled trials with long-term follow up are required to confirm the results.

Background: Lichen striatus (LS) is a linear, inflammatory dermatosis that mainly affects children. To date, there are limited data comparing treatment outcomes between topical agents for pediatric LS. Objective: To investigate the clinical features and treatment outcomes associated with the use of topical agents for pediatric LS. Methods: We retrospectively reviewed the medical records and clinical photographs of 60 pediatric patients classified into three groups according to the topical agent used. Treatment response was evaluated by comparing subjective symptoms and clinical photographs obtained at each visit. Results: A good response (>75% clinical improvement from baseline) was achieved in 55%, 46.2%, and 42.9% of patients from the calcipotriol, corticosteroid, and calcineurin inhibitor groups, respectively. There were no statistically significant differences in treatment duration among groups. However, when compared to other drugs, calcipotriol showed a trend towards shortening the disease course duration. Conclusion: Topical use of calcipotriol, as well as corticosteroids and calcineurin inhibitors, may represent useful treatment options for pediatric LS, although further studies are required to confirm their efficacy and long-term safety.
