Résumé
Serum sickness-like reaction (SSLR) is an abnormal self-limited reaction that can cause fever, myalgia, fatigue, lymphadenopathy, arthralgia, and skin rashes. Its etiology is yet unknown; however, SSLR often develops in patients with hepatitis B and after drug and vaccination administration. SSLR's typical cutaneous manifestations include polycyclic, erythematous wheal-like or plaque-like lesions. A 47-year-old male hepatitis B carrier visited our emergency department with high fever and multiple annular erythematous plaques with clear centers on his trunk and upper and lower extremities. The patient's hematologic laboratory results indicated an acute exacerbation of hepatitis B, and his symptoms correlated with those of SSLR. Here, we report a case of SSLR in a patient with an acute exacerbation of hepatitis B with clinical, hematological, and histopathological evidence.

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.

Terra firma-forme dermatosis (TFFD) is a bizarre, acquired and idiopathic dermatosis that etiology has still not been fully defined. It is characterized by the presence of asymptomatic, brownish dirt-like lesion maybe due to disorder of keratinization. These lesions cannot be removed with ordinary cleansing. Therefore, TFFD can be differentiated from dermatosis neglecta. Patient was a 17-year-old man with brownish lesions on his face for 1 month. The patient had a history of regular washing habit with soap and water. The lesions were asymptomatic however due to cosmetic reasons, the patient wanted to treat his skin lesions. Punch biopsy revealed hyperkeratosis and fungal spore are in stratum corneum. Salicylic acid peeling with alcohol base was performed on the patient's face. The skin lesions disappeared completely on gentle swabbing with peeling. In this point, the diagnosis of TFFD could be considered. Since, this disease can be confused with dermatosis neglecta, we report this case with literature review.

BACKGROUND: Growth factor treatment in combination with microneedling in androgenetic alopecia (AGA) patients is safe and effective. However, there is a lack of studies examining the effect of treatment according to the depth of the microneedle. OBJECTIVE: The aim was to evaluate differences in efficacy according to the depth of microneedle. METHODS: This study was performed on 6 male and 5 female AGA patients who were treated with topical growth factor cocktail (GFC) with microneedling every 2 weeks for 3 months. The scalp was divided into right and left sides and treated with microneedle depths of 0.5 and 0.3 mm, respectively. GFC was topically applied using a microneedle medical device. Treatment efficacy was evaluated by phototrichogram and digital photograph analysis on 6 repeated treatments for 3 months. RESULTS: Phototrichogram of the 0.5- and 0.3-mm-treated sides of the scalp showed 19 and 12 cm2 increase in hair density and 2.6- and 1.8-µm increase in hair diameter, respectively. These results were statistically significant (p0.05). CONCLUSION: GFC treatment with microneedling is effective and safe and a microneedle depth of 0.5 mm appears to be more effective than that of 0.3 mm. More research is necessary to confirm these results and determine the most effective depth for microneedling by investigating various depths.

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.

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.
