RESUMEN
Spider angioma (SA) may present as solitary or multiple lesions. Studies have shown that approximately 60% of pregnant women and 38% of healthy children have at least one spider telangiectasia. Hence, solitary SA in an otherwise healthy individual does not warrant further workup. However, multiple spider angiomas (MSAs) are usually suggestive of an underlying systemic disease. Physical examination for MSAs has been reported as the most reliable method to diagnose alcoholic liver cirrhosis; the presence of MSAs is more indicative of liver cirrhosis than just the history of alcohol use because a very low proportion of alcohol drinkers among the general population develop liver cirrhosis. We report a case of MSAs in a 42-year-old alcoholic woman suggesting that MSA is reliable indicator and a warning sign of liver cirrhosis, suggesting that further evaluation and management with the department of hepatology is necessary.

Although the dermoscopy had very long history since its introduction in 17th century, only recently it has been possible to see the widespread application of dermoscopy in the dermatology clinic. One of the most promising areas where the dermoscopy can be applied is the diagnosis of skin cancer, especially malignant melanoma. Due to its inherent limitation to obtain in-depth information—literally, from more than skin-deep and more importantly, from microscopic structures—of skin cancers, dermoscopy cannot replace the present gold-standard ‘biopsy’ in the diagnosis of skin cancer. However, several advantages of dermoscopy over biopsy merit further considerations. For example, as a non-invasive tool, dermoscopy is best suited for the follow-up of suspicious skin lesions, and as an all-at-a-glance tool, dermoscopy can aid the selection of the best biopsy-site to obtain the most meaningful pathological information from the minimal tissue specimen. There goes a saying that ‘it takes two to tango,’ similarly, we might need the two (biopsy and dermoscopy) to cope rhythmically with the varying tempos of ever-progressing skin tumorigenesis and to reveal the true face of skin cancers usually hidden in various disguises.

Lipedematous alopecia (LA) is a rare disease entity that manifests as increased thickness of subcutaneous fatty tissue in the scalp with a variable degree of acquired, non-scarring alopecia. Although the pathogenesis of alopecia in LA is not clear, it is assumed that the increased thickness of subcutaneous fat retards hair growth by disturbing the peripheral microenvironment of the hair bulb. LA is clinically distinguishable from lipedematous scalp (LS) in that LS is not associated with any hair abnormalities, while LA is characterized by variable degree of hair loss. However, both LA and LS share increased scalp thickness. Here, we describe a rare case of LA on the frontal scalp of an Asian woman, further characterize the clinical and histologic features, and suggest applying an integrated diagnosis as lipedematous diseases of the scalp.

Focal acral hyperkeratosis (FAH) is a rare genodermatosis inherited by autosomal dominant transmission; however, some sporadic cases have also been reported. FAH is characterized by multiple late-onset crateriform hyperkeratotic papules with a yellow color on the border of the hands and feet. A 31-year-old man presented with yellowish discrete flat-topped papules on the lateral side of his palms and fingers. The patient had a family history of similar lesions throughout three generations. The histological findings revealed hyperkeratosis with mild hypergranulosis in the epidermis, and the dermis showed no specific changes including elastorrhexis. These clinicopathologic findings were consistent with the diagnosis of FAH. Herein, we report a rare case of FAH with autosomal dominant inheritance.

PURPOSE: There is an unmet need for the treatment of moderate-to-severe atopic dermatitis (AD), leading to variation in management strategies. To investigate distinct features and treatment modalities according to physicians' specialties, we collected data on the current treatment approach to moderate-to-severe AD among allergists, pediatric allergists and dermatologists in Korea. METHODS: This questionnaire-based study was administered to physicians from the Korean Academy of Asthma, Allergy and Clinical Immunology (KAAACI), Korean Academy of Pediatric Allergy and Respiratory Disease (KAPARD), and Korean Atopic Dermatitis Association (KADA). RESULTS: A total of 93 physicians participated in the study; 64.5% were pediatric allergists and 31.2% were dermatologists. The major patient age groups were “less than 5 years” for 100% of pediatric allergists and “6–12 years old” for 38% of dermatologists. The proportion of patients with moderate-to-severe AD was higher for dermatologists and allergists compared to pediatric allergists. Physicians agreed on the necessity of education including demonstration of basic skin care and application of topical therapies (88.2%), nutritional consultation (83.9%) and psychological counseling (75.3%). However, less than half were able to educate and counsel their patients in real practice. There were noticeable differences in first-line treatment among physician groups. For pediatric allergists, the order of preferred systemic treatment was wet wrap therapy, systemic corticosteroids and oral cyclosporin. Dermatologists ranked cyclosporin, phototherapy, and systemic corticosteroids as first-line treatment regimens. Major reported barriers to proper management were steroid phobia, unproven complementary and alternative medicine, lack of education, and the unreasonable insurance system. CONCLUSIONS: Our findings suggest there are distinct differences in moderate-to-severe AD treatment according to physicians' specialties. Medical policy changes along with governmental supports are required in order to implement the ideal approach in real practice. For moderate-to-severe AD, a consensus on the approach to optimal management should be reached for the best outcomes, based on further randomized controlled trials.

RESUMEN
Protothecosis is an unusual human infection, caused by the genus prototheca, especially Prototheca wickerhamii. A 80-year-old immunocompetent man presented with a 1-month history of multiple reddish brown lobulated plaques on the scalp and face. He denied any history of trauma and had no evidence of underlying diseases such as diabetes mellitus or malignancy. On histopathological examination, characteristic morula-like sporangia in the dermis was revealed. After treatment with oral itraconazole for 8 weeks, the patient's skin lesions are almost healed.

PURPOSE: Questionnaire-based diagnostic criteria for atopic dermatitis (AD) have been proposed to detect the major group of AD with flexural dermatitis. We aimed to develop novel, questionnaire-based diagnostic criteria for childhood AD, which can detect more comprehensive AD including non-flexural type. METHODS: The draft version of questionnaire to detect childhood AD was prepared to be used for preliminary hospital- (n=1,756) and community-based (n=1,320) surveys. From analysis, the Reliable Estimation of Atopic dermatitis of ChildHood (REACH) was derived and verified in derivation (n=1,129) and validation (n=1,191) sets by community-based surveys. RESULTS: The REACH consists of 11 questions including 2 major and 9 minor criteria. AD is diagnosed as the major group of 'eczema on the antecubital or popliteal fossa' to fulfill the 2 major criteria (2M), and the minor group of 'eczema on the non-antecubital or popliteal fossa' to fulfill the 1 major plus 4 or more minor criteria (1M+4m). In the validation set, the overall 1-year AD prevalence by the REACH was estimated as 12.3% (95% CI, 10.5%-14.2%), and the REACH showed a sensitivity of 75.2%, a specificity of 96.1%, and an error rate of 6.4%. The REACH demonstrated better diagnostic performance than the ISAAC in terms of the number of misclassification (10.0%). CONCLUSIONS: We propose the REACH as new full, questionnaire-based diagnostic criteria for childhood AD in epidemiological surveys. Further studies are warranted to validate the REACH in different populations or countries in the context of large-scale, epidemiological surveys.

Research of the FLG mutation in various ethnic groups revealed non-overlapping mutation patterns. In addition, Japanese and Chinese atopic patients showed somewhat different mutations. These ethnic differences make the research on Korean patients mandatory; however, no systematic research on Korean atopic dermatitis (AD) patients has been performed. This study aims to investigate the genetic polymorphism of FLG in Korean atopic dermatitis patients. The study was made up of three groups including 9 Ichthyosis vulgaris (IV) patients, 50 AD patients and 55 normal controls: the ichthyosis group was incorporated due to the reported association between the FLG mutation and IV. In comparison to other sequencing methods, the overlapping long-range PCR was used. We revealed the genetic polymorphism of filaggrin in Koreans, and at the same time, we discovered nonsense mutations in p.Y1767X and p.K4022X in Korean AD patients. By using FLG sequencing techniques confirmed in this study, new mutations or genetic polymorphisms with ethnic characteristics would be detected and further larger studies of repeat number polymorphisms could be performed.

Neck wrinkles commonly develop owing to the aging process. However, recently, the number of patients with neck wrinkles has been increasing. Also, an increasing number of young patients have presented with this condition, possibly because of the effect of the head-down posture that they adopt when using their computer or smartphone. We report two cases of young adults with a prominent neck wrinkle. In case 1, a 29-year-old woman with a neck wrinkle was treated with six intradermal radiofrequency (RF) procedures. Her neck wrinkle was significantly improved with the RF treatment. In case 2, a 32-year-old woman with a wrinkle and generalized light brownish tiny papules on the neck was treated with three intradermal RF procedures simultaneously with 30% glycolic acid peeling. Her wrinkle and skin tone were improved dramatically. We conclude that intradermal RF has a considerable efficacy for reducing neck wrinkles.
