Symposium 2-2-13 (SYP 2-2-13) : A patient with purpura
김혜성 ( Hei Sung Kim ) 대한피부과학회 2015 대한피부과학회 학술발표대회집 Vol.67 No.1
1. Diagnosis Amyloid purpura 2. Clinical summary A 55-year-old male was referred to the department of dermatology for evaluation of asymptomatic, multiple, variably sized, purpuric lesions on the periocular area and the lower abdomen for months. The patient had chronic obstructive pulmonary disease (COPD) and was recently admitted to the department of pulmonary medicine due to breathing difficulty. A skin biopsy was performed from the abdomen for analysis. 3. Microscopic features Histology showed pale-pink amorphous material deposition in the upper dermis. Congo red staining showed apple-green birefringence under polarized light microscopy. 4. Discussion Bilateral periorbital purpura or ‘raccoon eyes’ has been described in association with skull trauma, and as in our case with primary amyloidosis. Amyloidosis is divided into three categories: primary, secondary and hereditary. Primary or AL amyloidosis results from an abnormal proliferation of plasma cells with deposition of fragments of monoclonal proteins (light chains) in tissues; the heart, kidneys, central nervous system and GI tract are the commonly involved organs. Other less common manifestations include cutaneous purpura. Amyloid purpura has a propensity for involving skin folds, such as the eyelids. Increased capillary fragility and infiltration of their walls with amyloid deposits can cause rupture of these small vessels with mild perturbations such as coughing, sneezing. Although a careful history and physical examination can guide clinicians toward the diagnosis of amyloidosis, it is confirmed on biopsy, by revealing amyloid fibril deposition in tissues. Congo red staining, which leads to the appearance of apple green birefringence is used as a diagnostic test. 5. References Eder L, Bitterman H. Amyloid purpura.

DIY 1 (DIY 1) : Receptors, channels and neural pathways of itch
김혜성 ( Hei Sung Kim ) 대한피부과학회 2015 대한피부과학회 학술발표대회집 Vol.67 No.1
Itch (pruritus) is defined as an unpleasant sensation that evokes the desire to scratch. Older studies have interpreted itch as a type of pain. However, recent neurophysiological findings have provided evidence that itch is a separate sensory modality. A novel pruriceptive system has been proposed within which itch-producing peripheral mediators (pruritogens), itch-selective receptors (pruriceptors), sensory afferents and spinal cord neurons, and itch-processing central nervous system regions display complex, layered responses to itch. Recently, special attention has been attracted to the transient receptor potential (TRP) superfamily as a “player” in the pathogenesis of pruriceptive itch. My talk will be covering the basic mechanism of itch with special focus on thermosensitive TRP channels.
Mini Lecture 2 : Cosmetic dermatology: the basics
김혜성 ( Hei Sung Kim ) 대한피부과학회 2015 대한피부과학회 학술발표대회집 Vol.67 No.1
In this lecture, I will be reviewing the clinical and histological features of the common pigmentary disorders (ex. lentigo, Becker’s nevus, cafe au lait macule, Ota nevus, blue nevus, melasma, PIH, melanocytic nevi) as well as lesions commonly treated by lasers (ex. seborrheic keratosis, skin tags, verruca plana). Right afterwards, an overview will be made on lasers used in the dermatologic field followed by the point-to-point matching of lasers (including the parameters) to the individual skin lesion. My personalphotos taken before and after treatment will be shown to help understand the effects of laser treatment. The lecture is for complete beginners in lasers - following the talk, one will be able to gain a sound understanding on the different pigmentary disorders and choose optimal treatment. Table of Contents 1. Common pigmented lesions (Clinical findings, histology) 2. Other common lesions treated by LASER 3. Overview of Pigment/Ablative LASERS 4. Before and After photos
Symposium 1-5 (SYP 1-5) : Perfume for the treatment of acne
김혜성 ( Hei Sung Kim ) 대한피부과학회 2015 대한피부과학회 학술발표대회집 Vol.67 No.1
Acne is a prevalent, chronic, and sometimes severe skin disorder affecting an estimated 85% of adolescents and 50% of adults older than 20 years. The psychosocial implications of acne can be considerable, often continuing long after physical symptoms resolve. Although effective acne medications are available, most exhibit adverse effect profiles that can leave the patient with few effective treatment options. Emerging evidence indicates that plant-derived essential oils may be a biologically plausible treatment for acne, although high-quality evidence of effectiveness and safety is lacking. Essential oils have many different therapeutic properties including anti-bacterial, antiseptic, anti-inflammatory, astringent and balancing and some are especially known to be good for acne skin-care. They heal and nourish the skin, and can help reduce inflammation. Tea tree is probably one of the best known essential oils for treating acne, particularly for its anti-bacterial properties but also for its general healing nature. Other oils that are beneficial include: Benzoin, bergamot, eucalyptus, grapefruit, german chamomile, jasmine, lavender, lemon, lemongrass, patchouli, rosewood, sandalwood and ylang ylang. In this session, I will briefly discuss the possible beneficial effects of essential oil aromatherapy on acne.
