Condyloma lata is one of the cutaneous manifestations of secondary syphilis. They are extremely infectious, moist papules that are commonly seen on patients with secondary syphilis. Condyloma lata commonly affects the intertriginous skin, and especially that of the genitalia, the perianal area and axilla, which all suffer from heat, moisture and friction. However, they are rarely seen on the tongue. A 19-year-old male patient presented with multiple erythematous papules and plaques on the tongue. But he did not have any other cutaneous eruption. Histopathological findings revealed irregular epidermal hyperplasia and perivascular inflammatory cell infiltration with lymphocytes and plasma cells in the dermis. The VDRL and TPHA test were both positive. (Korean J Dermatol 2010;48(9):804~806)

Crusted (Norwegian) scabies is a clinical variant of human infestation with Sarcoptes scabiei, and is characterized by extensive, heavily crusted skin lesions. It usually affects immunocompromised patients. The diagnosis is commonly missed, and can lead to mismanagement. Here we report a case of crusted scabies misdiagnosed as a cutaneous side reaction due to allopurinol in a 48 year old male patient with acquired perforating dermatosis who had been treated with allopurinol for about 20 weeks. The lesion showed pruritic, excessive hyperkeratotic scaly crusts and fissures on the hands, and on pelvic, genital and inguinal areas. His skin lesions disappeared after treatment with 10% crotamiton cream for 2 weeks. (Korean J Dermatol 2011;49(3):287∼290)

Hidradenitis suppurativa is a chronic, relapsing suppurative disease of the apocrine sweat glands that principally affects the axillary and anogenital regions. The etiology of this disorder remains unknown. As conservative treatment usually does not prevent recurrence, surgical treatment is the method of choice, particularly for advanced case. We report a 25-year-old male patient who presented with a 7-year history of abscesses with foul-smelling discharge from his axilla. After failed medical therapy, he was referred for surgery. We performed a wide excision of the axilla with a split thickness skin graft after 1 week. The patient has been doing well, and there has been no relapse for about ayear after the operation.

Eccrine poroma is a benign neoplasm, arising from the eccrine sweat duct. It generally occurs in middle aged individuals and is most commonly found on the sole or the sides of the foot, followed by the hands and fingers. It presents as a solitary, soft or a rather firm consistent, sessile or often slightly pedunculating, tumor. A 47-year-old woman presented with a 2.5×1.5 sized brownish to erythematous pedunculating mass on the left flank. According to histopathologic finding and immunohistochemical staining (epithelial membrane antigen), the final diagnosis was consistent with eccrine poroma. We report here on an interesting case of eccrine poroma presenting as pedunculating mass on the flank, which is an unusual location. (Korean J Dermatol 2012;50(7):647∼649)

Pincer nail deformity is a nail deformity characterized by a transverse overcurvature of the nail plate, which increases along the longitudinal axis. Many conservative and surgical treatment modalities have been reported. Conservative methods can be difficult to use in cases of severe deformity because of their high recurrence rate. Therefore, surgical techniques, including nail matricectomy or correction of the nail bed, have been preferred in these cases. Matricectomy is generally considered as the surgical treatment of pincer nail deformity because of low recurrence rate in the field of dermatology. However, poor cosmetic results (e.g. narrowing of nail plate) are frequently observed. We present here a case of pincer nail deformity in the left great toe in a 57-year-old man who was treated successfully with widening of the nail bed without matricectomy. This method is an effective surgical technique preserving the nail matrix for the correction of pincer nail deformity. (Korean J Dermatol 2012;50(5): 451∼455)
국내 환경기초시설 실내악취 사례분석을 통한 환기설비 개선방안

The purpose of this study is to investigate the current status of indoor odor in the sample domestic environmental foundational facilities and to identify the main parts and reasons for improving the design of ventilation equipment. The effectiveness of air ventilation in one of those facilities was evaluated by the age of air at the worker’s breathing height, CFD simulated by DesignBuilder 4.7. As a result, when the air supply diffuser was installed close to the worker’s breathing height, the age of air was reduced by 70% compared to the current practices that supply diffusers were installed near the ceiling. That is, the air ventilation can be improved by installation of air supply diffuser at the breathing height.
가족력 없이 전신 피부에 광범위하게 발생한 과각화성 다리에 병

Darier`s disease is an uncommon inheritable genodermatosis that is characterized by recurrent waxy, hyperkeratotic papules that usually occur over the seborrheic areas. The characteristic histopathological changes are acantholysis leading to the formation of lacunae and dyskeratosis with corps ronds and grain, which are diagnostic clues of the disease along with the typical clinical features. A 50-year-old Korean male patient presented with an extensive involvement of whitish thick hyperkeratotic fissures, verrucoid plaques with oozing and foul odor over the skin for about 30 years. We report here on an unusual case of extensive cornifying Darier`s disease in a patient who has no family history of this disease. (Korean J Dermatol 2010;48(10):898~901)
각화극세포종과 편평세포암에서 Lysyl Oxidase (LOX)의 발현: 감별진단에의 유용성

Background: Because keratoacanthoma (KA) and squamous cell carcinoma (SCC) are very similar with respect to clinical and histological features but are different with respect to prognosis and treatment, it is necessary to differentiate these two diseases. A number of recent studies have been attempted to differentiate these two diseases using immunohistochemical stains; however, the results obtained using these approaches were inconsistent. Objective: The purpose of this study was to examine the expression pattern of polyclonal antibody to lysyl oxidase (LOX) on KA and SCC using an immunohistochemical staining method, and to evaluate the ability of this method in distinguishing these two diseases. Methods: The expression of LOX in 10 cases of KA and 10 cases of SCC, which were confirmed by histopathologic examination, and 10 cases of normal human skin as a control, were evaluated using an immunohistochemical staining method. We divided the degree of immunohistochemical staining into three classifications --high density, low density, and no density-- based on the level of the expression of LOX in the epidermis and the tumor. Evaluation of the immunohistochemical staining was performed by two dermatologists and one pathologist. Results: The rates of high, low, and no density in KA were 50%, 50%, and 0%, respectively. The rates of high, low, and no density in SCC were 40%, 10%, and 50%, respectively. The rates of high, low, and no density in the control group were 70%, 30%, and 0%, respectively. Conclusion: Because the degree of LOX expression in KA and SCC was very diverse, it could not be reliably used as a differential stain for the two diseases. But interestingly, no LOX expression was observed in SCC. This suggests that if expression of LOX is absent, there is a high probability of being diagnosed with a malignant skin tumor rather than a benign skin tumor. (Korean J Dermatol 2012;50(3):220~226)
