Background: Scabies is an ectoparasite caused by the mite Sarcoptes scabiei var. hominis, an obligate human parasite. Although its incidence has been decreasing, it is not a rare dermatologic disease and is difficult to diagnosis. Objective: To evaluate the clinical characteristics of scabies patients and find out etiologic factors in transmission. Methods: Two hundred and ninety-five patients who were diagnosed with scabies at the Dermatologic Department,Myongji Hospital, Goyang city, Korea were enrolled. Medical records were evaluated in a retrospective manner. Results: We studied 295 scabies patients who were diagnosed by the mineral oil test or skin biopsy. The mean age of the patients was 58.2 (male: 56.7/female: 61.2), and 74% of patients were over 60 years. There was seasonal variation in occurrence, and scabies was found to be most common in winter. The majority of suspected routes of infection were transmission through convalescent hospitals (38.1%) and caregivers (15.2%). Nosocomial infection and communal living were the major causes. 73.8% of scabies patients had underlying medical disease, such as hypertension (32.2%) and dementia (11.9%). Conclusion: Currently, scabies prevalence is still increasing in Goyang city, because of the increased number of convalescent hospitals.

Background: Viral warts are common viral infections and are usually self-limiting. However, there have been few studies assessing the characteristics of patients with viral warts. Objective: The purpose of this study was to assess the epidemiological and clinical characteristics of viral warts during a five-year-period. Methods: We carried out a retrospective analysis of patients with viral warts who had been diagnosed in the Myongji hospital from January 2007 to December 2011. Results: One thousand seven hundred and ninety patients with viral warts were assessed. A group of patients aged under 10 years had the highest occurrence of common warts (46.8%). The mean age was 16.9 years. Hands (47.7%) were more commonly involved than feet (36.4%). Cryotherapy was used to treat most of the patients. One thousand and sixty-one patients (59.3%) showed complete resolution of the wart lesion in the clinical ground. Conclusion: The number of patients with viral warts is currently increasing. This study provides useful data on the prevalence and characteristics of viral warts. (Korean J Dermatol 2013;51(8):593∼599)

Eruptive vellus hair cysts (EVHCs) are small, red- or brown-colored cystic papules that usually occur on the chest and proximal extremities of children and adults. Histologically, these small cysts are observed in the mid-dermis and contain multiple hair shafts and keratinous material. Pathogenesis of EVHC has not been completely understood. A 40-year-old man with mental retardation presented with multiple bluish papules on his back. A biopsy specimen showed features of eruptive vellus hair cysts. We report a case of EVHC that occurred at an unusual site in a patient with mental retardation. (Korean J Dermatol 2017;55(5):290∼292)
