Intravascular papillary endothelial hyperplasia (IPEH) is a rare benign vascular tumor characterized by the development of endothelial-lined papillary projections in the vascular lumen. Most authors believe that IPEH represents an unusual pattern of organizing thrombus, implying that a thrombus is the initial cause. A 13-year-old boy came to hospital because of a purpuric patch and violaceous plaque on his right forearm. Clinically, the lesions were thought to be a hemangioma or other vascular malformation. Therefore, we treated him with intense pulsed light (IPL) four times. After treatment, the initial skin lesions were erythematous and edematous and a new bluish mass and multiple scattered subcutaneous nodules appeared near the original skin lesions. Histologic examination of the new bluish mass showed an organic thrombus and endothelial-lined capillary projections in the dilated vascular lumen, compatible with IPEH. Here, we report an interesting case of IPEH after IPL treatment in a 13 year-old boy. (Korean J Dermatol 2008;46(2):234∼237)

Proliferating trichilemmal cyst is a rare benign tumor of external root sheath origin that usually occurs on the scalp of elderly women. It is rarely found on the face, neck, trunk and back. A 17 year-old man presented with a skin- colored, subcutaneous, tender nodule on the elbow with a history of bee sting. A histological examination revealed a well demarcated multilobular cystic mass characterized by trichilemmal keratinization in the dermis. The skin lesion was totally excised and recurrence has not been found. We present a case of proliferating trichilemmal cyst of unusual predilection site. (Korean J Dermatol 2008;46(3):381∼383)

Background: Atopic dermatitis is a chronic relapsing inflammatory skin disease characterized by dry skin, pruritus, and typical distribution of the lesions. Because an objective tool for the assessment of disease severity of atopic dermatitis has yet to be agreed upon, many dermatologists are dependent on subjective history and clinical scoring. Recently, instrumental measurements have been used for the assessment of skin barrier function. Objective: The purpose of this study was to assess the correlation between SCORAD (scoring of atopic Dermatitis) index and the results of instrumental assessments of disease severity in atopic dermatitis. Additionally, we compared the values of instrumental measurements on normal and lesional skin. Methods: From February to April 2007, 44 patients with atopic dermatitis were treated with topical steroids, topical calcineurine inhibitors, oral antihistamine agents and systemic steroids. At initial visit, and after 1, 2, 3, and 4 weeks of treatment, the SCORAD index was measured, and instrumental measurements of skin surface hydration (SSH), transepidermal water loss (TEWL), and pH were performed on the antecubital fossa (lesional skin) and flank (normal skin) of the patients by Corneometer(R), Tewameter(R), and skin-pH-meter(R). Results: Significant correlation was found between SCORAD index and SSH (p<0.0001), TEWL (p<0.0001), and pH (p=0.1680). SSH and TEWL improved within 1 week of treatment but pH improved after 2 weeks of treatment. Instrumental assessments showed lesional skin had lower SSH, higher TEWL, and more alkaline pH than normal skin. Conclusion: Instrumental measurements showed correlation with SCORAD index. Therefore, we can use instrumental assessments as well as SCORAD index in the assessment of disease severity of AD. (Korean J Dermatol 2010;48(4):266~271)

N/A Background: Long-standing atopic dermatitis patients frequently predispose to ocular complications. The ectoderrnal origin of the epidermis and of many eye structures explain the fre~quent associations observed in atopic dermatitis. Objective: This study may help in evolving early diagnosis a~nd in formul~ating standard therapeutic strategies to prevent and treat ocular complications by studying the types, frequency and dermatological characteristics of each ocular complication in atopic dermatitis. Methods: We evaluated the ocular complications of 4I typical atopic dermatitis patients(26 males, 15 females) who had skin lesion around eyelids or complained of ocular symptoms. Results: Mean age of the patients was 17.7 years. The onset of atopic dermatitis was during infancy in 21 patients, during chiildhood in 15 patients, and during adult in 5 patients and their mean duration of disease was 13.8 years. Mild ocular involvements including blepharitis in 29 patients(58 eyes, 70.7%), keratoconjunctivitis in 29 patients(58 eyes, 70.7%) were seen. More serious com- plications which may lead to decreased visual function including cataracts in 5 patients(10 eyes, 12.1%), retinal detachments in 3 patients(5 eyes, 6.0%) were seen. All the patients who had these two s~erious complications had facial dermatitis. And other ocular invo~lvements including keratoconus in 2 patients(2 eyes, 2.4%), ocular herpes simplex in 1 patient(2 eyes, 2.4%), uveitis in 2 patients(2 eyes, 2.4%) were seen. Conclusion . It is important to perfonn an ophthalmologic examination in the earl~y period of disease in long-standing atopic dermatitis patients especially those who have facial dermatitis for the early diagnosis and treatment of serious sight-threatening complications.
반복된 열상 후 조갑하 소피에 발생한 점액성 신경섬유종

We report a case of a 32-year-old woman with a myxoid neurofibroma occurring on the hyponychium of the 4th finger following repeated laceration. The tumor was histologically determined to be a myxoid neurofibroma. Myxoid neurofibroma may present as a sporadic lesion or in the context of neurofibromatosis 1. Although there is no predilection site of solitary lesion, occurrence on the hyponychium is rare. We report a case of solitary neurofibroma on the hyponychium of the 4th finger following repeated laceration. (Korean J Dermatol 2008;46(3):391∼393)

Accumulation of calcium in the skin is usually classified as a group of disorders referred to as calcinosis cutis. Based on pathophysiologic mechanisms, it has been classified as metastatic, dystrophic, idiopathinic and iatrogenic calcinosis cutis. Local tissue injury due to repetitive trauma by an acupuncture needle can cause dystrophic calcinosis cutis. A 61-year-old woman developed hyperpigmented pea sized subcutaneous nodules on the right side of her lower abdomen. She had received several sessions of acupuncture treatments on the right abdomen in a herb medicine clinic. A biopsy specimen showed amorphous basophilic deposits in the dermis and serum levels of calcium, phosphate were within the normal range. We report a case of dystrophic calcinosis cutis following acupuncture treatments by a herb medicine doctor. (Korean J Dermatol 2008;46(6):839∼841)

Pseudoxanthoma elasticum is a rare, heritable disorder of elastic fibers characterized by yellowish, coalescing papules on the loose and wrinkled flexural skin. An 18-year-old man presented cutis laxa-like marked wrinkling on the axillae, trunk and thighs for about 10 years. There was no similar skin lesion on his family members and no other systemic involvement was found. Histopathological examination of the abdomen revealed fragmentation and calcification of elastic fibers in the middle and lower dermis. Von Kossa staining showed calcium deposition along the altered elastic fibers. Herein, we report a rare case of autosomal recessive pseudoxanthoma elasticum presenting generalized cutaneous laxity.
