On behalf of the host society, Chinese Society of Dermatology, I cordially invite all of you to Beijing and to this meeting. EADC is the official congress of Chinese Society of Dermatology (CSD), Japanese Dermatological Association (JDA) and Korean Dermatological Association (KDA). The similar traditional culture and rapid development in eastern Asia characterize this congress both regional and international. We all know that the 1st EADC that was held in Fukuoka Japan in 2010 was very successful. The 2nd EADC will follow the footsteps of 1st EADC, focusing on the international frontiers and hot spots of dermatology, covering both clinical and basic research area. I hope that this congress would be also productive and fruitful. Finally, this meeting will provide a great opportunity for participants to communicate with each other and will strengthen the friendship between participants as well as all dermatologists in this region. Beijing is the capital of China. It is an old city with thousands years’ history. Also it is an advanced, active and friendly city. I hope that all of you will be able to enjoy the scenery, the history and the culture of Beijing during your stay. I hope that the 2nd EADC will be an exciting and memorable experience to all of you. Looking forward to welcoming you in Beijing! Jianzhong Zhang President of Host Society, Chinese Society of Dermatology The 2nd Eastern Asia Dermatology Congress Professor, Department of Dermatology Peking University People's Hospital www.cmacsd.org/eadc2012 www.cmacsd.org/eadc2012 03 2nd Eastern Asia Dermatology Congress 2nd Eastern Asia Dermatology Congress June 13-15, 2012 Beijing, China Welcome Message Dear friends and colleagues, It is my great pleasure and honor to welcome you as the JDA-appointed President of the 2nd Eastern Asia Dermatology Congress (EADC). After a few years’ discussion among CSD, KDA and JDA, the EADC was formally founded by inter- society agreements in 2009. The establishment of EADC has been made possible by close friendship cultivated through a 30 year-history of the Korea-Japan Joint Meeting of Dermatology, and a 20-year history of China-Japan Joint Meeting of Dermatology. Under the leadership of three presidents, Profs. Masutaka Furue (host society, JDA), Xuejun Zhang (CSD), and Ki Hong Kim (KDA), the 1st EADC was successfully held in Fukuoka from September 30th to October 3rd, 2010, with more than 800 participants. The EADC is a unique organization founded on the concept of ‘society-based’ alliance, not of a ‘nation-based’ one. The 1st EADC meeting, therefore, was held under the auspices of the JDA (host society), CSA and KDA, excluding the country or nationality of participants. The scientific program was composed of plenary, concurrent oral and poster presentations after peer-review of all abstracts by the program committee members, and accepted abstracts have been published in the Journal of Dermatology, and Annals of Dermatology. The published abstracts, therefore, are available for citation, and simultaneously require the author’s responsibility. The 2nd EADC will be held in Beijing from June 13th to 15th, 2012 with a deeper inter-society friendship and commitments of CSD (host society), KDA and JDA. As described in the bylaws, the main purposes of the EADC are to increase knowledge of bio- and patho-physiology of the skin, cutaneous disorders, and their treatments, to foster collaboration among dermatologists and scientists in Eastern Asia, and to promote education and dissemination of scientific information by organizing meetings and sponsoring/supporting cooperative studies. To achieve these purposes, the EADC is charged to share our knowledge with all dermatologists in Eastern Asia. I believe that our EADC can accept this challenge. Please join us and enjoy the 2nd EADC in Beijing.

I believe that the 1st EADC held in Japan in 2010 gave a good opportunity to the dermatologists from three countries, China, Japan, and Korea, by providing invaluable social networking as well as a place to exchange the latest advancements in dermatology. With a great success to the 1st EADC, the 2nd EADC will extend this opportunity by a more extensive program including special lectures, symposia, and free paper sessions and make itself more fruitful and productive. In addition, this congress will provide you with an excellent opportunity to gain better insight into recent researches. I expect that EADC can be one of the most regional and international professional meetings in the near future. I sincerely hope you will take opportunity to share, enjoy and enrich yourself as a leading professional through this meeting I look forward to seeing you at the Beijing Meeting soon.

Abstract The aim of this study is to outline the common dermatological findings in pediatric rheumatologic diseases. A total of 45 patients, nineteen with juvenile idiopathic arthritis (JIA), eight with Familial Mediterranean Fever (FMF), six with scleroderma (SSc), seven with systemic lupus erythematosus (SLE), and five with dermatomyositis (DM) were included. Control group for JIA consisted of randomly chosen 19 healthy subjects of the same age and gender. The age, sex, duration of disease, site and type of lesions on skin, nails and scalp and systemic drug use were recorded. χ2 test was used. The most common skin findings in patients with psoriatic JIA were flexural psoriatic lesions, the most common nail findings were periungual desquamation and distal onycholysis, while the most common scalp findings were erythema and scaling. The most common skin finding in patients with oligoarthritis was photosensitivity, while the most common nail finding was periungual erythema, and the most common scalp findings were erythema and scaling. We saw urticarial rash, dermatographism, nail pitting and telogen effluvium in one patient with systemic arthritis; and photosensitivity, livedo reticularis and periungual erythema in another patient with RF-negative polyarthritis.

    Anetoderma Secondary to Mid-Dermal Elastolysis

    Anetoderma Secondary to Mid-dermal Elastolysis Gabriela A. Maloney, BS,* Jane James, MD, PhD,** Michael Welsch, MD,** Marylee Braniecki, MD** *Midwestern University, Downers Grove, IL **Pathology Department, University of Illinois Hospital & Health Sciences System, Chicago, IL Abstract Anetoderma usually presents as circumscribed, 1 cm to 2 cm patches and plaques of flaccid skin secondary to loss of dermal elastic tissue. Lesions often occur in the neck, upper extremities, chest, and back. On histopathology, one sees complete loss of dermal elastin involving the papillary and reticular dermis, with infiltration of plasma cells and histiocytes. A 40-year-old female with no significant medical history presented with multiple round, 1 cm to 2 cm lesions scattered on her upper back and chest. Skin biopsy demonstrated elastic-fiber loss localized to the mid-dermis along with a lymphohistiocytic infiltrate with elastophagocytosis and active inflammatory phase in the papillary and mid-reticular dermis. The histopathological findings were consistent with mid-dermal elastolysis with advancing inflammation, and the clinical features were consistent with anetoderma. The microscopic examination revealed an active inflammatory phase of mid-dermal elastolysis, supporting the postulated theory that MDE may be part of a continuous spectrum with anetoderma. Case Report by lax, wrinkled skin with underlying palpable biopsy and elastic-fiber staining demonstrated A 40-year-old female with no significant medical depression (Figure 1). They were often preceded elastic-fiber loss in the mid-dermis along with history presented with multiple round, 1 cm to by two to six months of local erythema and had a lymphohistiocytic infiltrate with evidence 2 cm lesions scattered throughout the upper increased in number over the past two years.

Caso Clínico Dermatose Degenerativa Induzida por D-penicilamina em Paciente com Doença de Wilson Rui Pedro Santos1, Joana Gomes2, Celeste Brito2 1Interno de Dermatovenereologia/Resident, Dermatovenereology, Hospital de Braga, Braga, Portugal 2Especialista de Dermatovenereologia/Specialist of Dermatovenereology, Hospital de Braga, Braga, Portugal RESUMO – As dermatoses degenerativas induzidas por D-penicilamina incluem, entre outras, a elastose perfurante serpiginosa e o pseudo-pseudoxantoma elástico. A elastose perfurante serpiginosa é uma doença perfurante rara caracterizada pela elimi- nação transepidérmica de fibras elásticas anormais. Esta condição pode ser idiopática, reativa ou induzida por D-penicilamina, habitualmente utilizada para o tratamento da doença de Wilson, cistinúria, artrite reumatóide ou esclerose sistémica. Manifesta- ções cutâneas semelhantes a pseudoxantoma elástico mas sem história familiar e mutações do gene ABCC6 foram identificadas como sendo uma dermatose induzida por D-penicilamina e designada de pseudo-pseudoxantoma elástico. Descreve-se o caso de uma mulher de 17 anos tratada por vários anos com D-penicilamina para doença de Wilson, com pápulas assintomáticas, algumas cor de pele e hiperqueratósicas e outras macias e amareladas, na região cervical e face. A histopatolo- gia mostrou a eliminação transepidérmica de fibras elásticas espessadas, em forma de dentes de serra. Estes achados sugeriram uma dermopatia induzida por D-penicilamina e os autores consideraram o diagnóstico de elastose perfurante serpiginosa e pseudo-pseudoxantoma elástico no mesmo paciente. O fármaco foi alterado para acetato de zinco sem lesões novas, mas com manutenção das lesões existentes no seguimento a 1 ano.

ABSTRACT Cutaneous apocrine carcinoma is an extreme rare malignancy derived from a sweat gland. Histologically sweat gland cancers resemble metastatic mammary apocrine carcinomas, but the genetic landscape remains poorly understood. Here, we report a rare metastatic case with a PALB2 aberration identified previously as a familial susceptibility gene for breast cancer in the Finnish population. As PALB2 exhibits functions in the BRCA1/2-RAD51-dependent homologous DNA recombination repair pathway, we sought to use ex vivo functional screening to explore sensitivity of the tumor cells to therapeutic targeting of DNA repair. Drug screening suggested sensitivity of the PALB2 deficient cells to BET-bromodomain inhibition, and modest sensitivity to DNA-PKi, ATRi, WEE1i and PARPi.

In a recent research on a well-known actinidine- and iridoid-producing ant species, Tapinoma melanocephalum (Fabricius) (Hymenoptera: Formicidae), no actinidine was detected in its hexane extracts by gas chromatography−mass spectrometry analysis using a common sample injection method, but a significant amount of actinidine was detected when a solid injection technique with a thermal separation probe was used. This result led us to hypothesize that heat can induce the production of actinidine in iridoid-rich organisms. To test our hypothesis, the occurrence of actinidine was investigated in four iridoid-rich organisms under different sample preparation temperatures, including two ant species, T. melanocephalum and Iridomyrmex anceps Roger (Hymenoptera: Formicidae), and two plant species, Actinidia polygama Maxim (Ericales: Actinidiaceae) and Nepeta cataria L. (Lamiales: Lamiaceae). Within a temperature range of 50, 100, 150, 200, and 250 °C, no actinidine was detected at 50 °C, but it appeared at temperatures above 100 °C for all four species. A positive relationship was observed between the heating temperature and actinidine production. The results indicate that actinidine could be generated at high temperatures. We also found that the presence of methylcyclopentane monoterpenoid iridoids (iridodials and nepetalactone) was needed for thermally induced actinidine production in all tested samples.
