Congenital hemangioma (CH) is a fully formed benign vascular tumor at the time of birth and do not proliferate in postnatal life. CH must be differentiated from infantile hemangioma. CH has three subtypes that are recognized based on their natural history: Rapidly involuting congenital hemangioma (RICH), non-involuting congenital hemangioma (NICH), and partially involuting congenital hemangioma (PICH). It is important to distinguish RICH from NICH because RICH spontaneously regresses but NICH does not. Herein, we report two patients diagnosed with RICH and NICH, respectively. We presented the clinical features as well as ultrasonographic and histologic findings to distinguish congenital from infantile hemangioma. (Korean J Dermatol 2018;56(9):556∼560)

N/A Background : The earlier laser treatment of patients with nevus flammeus or Ota nevus prevent psychologic dysfunction due to unwanted cutaneous lesion and the increasing size of lesion. Objective : Our purpose was to assess the safety and side effect of general anesthesia in the laser treatment of nevus flammeus or Ota nevus in children. Methods : 25 children treated with laser for nevus flammeus or Ota nevus and underwent general anesthetic modality were included in this study. The age of patients, the size and the location of cutaneous lesions were noted. Most of children, after induction of anesthesia with thiopental and succinycholine, were maintained airway with intratracheal intubation. Some of children was done with intravenous anesthesia, propofol or ketamine. The results of laser treatment were assessed by photograph and clinical observation, based on a scale: excellent for 75-100% improvement, good for 50-75% improvement, fair for 25-50% improvement, poor for 0-25% improvement. Results : 25 children treated with laser for nevus flammeus or Ota nevus were below 10 years old, eight of them were below 3 years old. The laser treatment was more effective in proportion with the number of laser treatment. After general anesthesia, all patients with laser treatment didn`t appear the side effect of laryngeal spasm or apnea etc. Our data showed minimal risk and sequale of general anesthesia in the treatment of nevus flammeus or Ota nevus in children. Conclusion : The use of general anesthesia in the treatment of nevus flammeus or Ota nevus in children does not appear to be accompanied by increased risk.

Background: Adult-onset Still`s disease (AOSD), one of the causes of fever of unknown origin, is accompanied by skin rash. This is the reason why the clinical significance of skin lesions has been of interest. However, its skin manifestations and the histopathological findings are not clearly documented. Objective: This study aimed to identify characteristic clinical and histopathological features of skin manifestation of AOSD. Methods: We evaluated the medical records and histopathologic slides of five patients who had been diagnosed with AOSD in the rheumatology department and referred to our department between 1996 and 2009. Results: An asymptomatic evanescent salmon colored macular rash was seen in three patients (60%). A persistent brown plaque was seen in two patients (40%). Histopathologically, superficial perivascular infiltrates of neutrophils and lymphocytes were observed in all patients (100%) and necrotic keratinocytes were observed in the upper epidermis in three patients (60%). Conclusion: In addition to typical Still`s rash, atypical cutaneous findings such as persistent plaque lesions were found in AOSD patients. The results of this study may help clinicians to diagnose this rare disease more easily. (Korean J Dermatol 2010;48(4):283~289)
