OBJECTIVE: This study was conducted to clarify the association factors and clinical significance of the CT angiography (CTA) spot sign and hematoma growth in Korean patients with acute intracerebral hemorrhage (ICH). METHODS: We retrospectively collected the data of 287 consecutive patients presenting with acute ICH who arrived within 12 hours of ictus. Baseline clinical and radiological characteristics as well as the mortality rate within one month were assessed. A binary logistic regression was conducted to obtain association factors for the CTA spot sign and hematoma growth. RESULTS: We identified a CTA spot sign in 40 patients (13.9%) and hematoma growth in 78 patients (27.2%). An elapsed time to CT scan of less than 3 hours (OR, 5.14; 95% CI, 1.76-15.02; p=0.003) was associated with the spot sign. A CTA spot sign (OR, 5.70; 95% CI, 2.70-12.01; p<0.001), elevated alanine transaminase (GPT) level >40 IU (OR, 2.01; 95% CI, 1.01-4.01; p=0.047), and an international normalized ratio > or =1.8 or warfarin medication (OR, 5.64; 95% CI, 1.29-24.57; p=0.021) were independent predictors for hematoma growth. Antiplatelet agent medication (OR, 4.92; 95% CI, 1.31-18.50; p=0.019) was significantly associated with hematoma growth within 6 hours of ictus. CONCLUSION: As previous other populations, CTA spot sign was a strong predictor for hematoma growth especially in hyper-acute stage of ICH in Korea. Antithrombotics medication might also be associated with hyper-acute hematoma growth. In our population, elevated GPT was newly identified as a predictor for hematoma growth and its effect for hematoma growth is necessary to be confirmed through a further research.

BACKGROUND: Although there have been many studies about onychomycosis, no study about Koreans in onychomycosis has been reported in Korea. OBJECTIVE: The purpose of this study was to investigate the onychomycosis in Koreans. METHODS: From April, 2009, to March, 2010, 1,893 patients with onychomycosis who visited the department of dermatology at 10 university hospitals were evaluated. RESULTS: Of 1,893 patients with onychomycosis, 93.8% were toenail onychomycosis, 2.2% fingernail onychomycosis, and 4.0% onychomycosis in both toenails and fingernails. Among the age groups, the incidence rate was highest over the sixties (35.6%). The ratio of male to female patients was 1.3:1. Distal and lateral subungual onychomycosis (80.3%) was the most common clinical type of onychomycosis. Combination therapy of oral terbinafine or itraconazole and topical amorolfine nail lacquer was most common in the treatment of onychomycosis. The most common reasons for combination therapy in onychomycosis were higher cure rate due to synergistic activity (40.2%), followed by shortened treatment duration (12.8%), patient compliance (12.3%), and prevention of recurrence and reinfection (1.7%). CONCLUSION: Because of the increase in onychomycosis, we suggest the need of standard treatment guidelines for Korean patients with onychomycosis.

Mycobacterium chelonae is a rapidly growing atypical mycobacterium found in soil and water. In a healthy person, it causes cutaneous infection after an invasive procedure or surgery. Herein, we present a case of a 52-year-old man with multiple erythematous plaques and nodules on the back and left arm, and these occurred at the site of bee sting therapy by a herbal medical doctor. The histologic findings showed a granulomatous infiltration composed of numerous neutrophils, lymphocytes, eosinophils, histiocytes and multinucleated giant cells. Acid fast bacilli were detected by Ziehl-Neelsen stain and Mycobacterium chelonae infection was confirmed by an INNO-LiPA mycobacteria kit. The patient was treated with 1 g of clarithromycin and 200 mg of doxycycline for 6 months and his condition improved considerably.

We report the case of a 23-year-old woman who developed bowenoid papulosis of the vulva and subsequent periungual Bowen's disease. She had a history of a long standing periungual wart on her right thumb before the outbreak of periungual Bowen's disease. By HPV DNA chip, human papillomavirus (HPV) 11, 18 and 31 were identified from the periungual lesions, and HPV 11, 18 and 33 from the vulvar lesion. This case supports the theory of anogenital-digital spread of HPV, and proposes that the periungual wart may change into Bowen's disease by mucosal HPVs. To the best of our knowledge, this case is important as the first Korean case of periungual Bowen's disease concurrent with bowenoid papulosis of the vulva.

Granuloma annulare (GA) is a benign granulomatous disease. Although its etiology is not well understood, there are some reports about GA occurring after specific conditions such as sunburn, a tuberculin test, insect bites, viral diseases and trauma. Especially, in case of the auricular region which is vulnerable to trauma, it seems that GA has some relation with trauma. In 1992, Mills and Chetty proposed that repetitive minor trauma may be an important cause of auricular GA. Among the 5 cases of auricular GA that have been reported in the English literatures, 3 cases are assumed to be associated with repetitive minor trauma. Herein, we report on two cases of auricular GA that were thought to be associated with repetitive minor trauma.

A 62-year-old male developed a solitary asymptomatic nodule on the lateral aspect of the distal interphalangeal joint of the right great toe. Histopathologic findings demonstrated a myxoid cyst with a concomitant epidermal inclusion cyst. To the best of our knowledge, this is the first case of concurrent occurrence of digital myxoid cyst and epidermal inclusion cyst. Although the exact mechanism for developing a digital myxoid cyst and an epidermal inclusion cyst simultaneously at the same site is not explained, trauma might be a possible cause.

Eosinophilic, polymorphic, and pruritic eruption associated with radiotherapy (EPPER) is a disorder characterized by polymorphic papules, vesicles, and excoriations accompanied by a local or general itching sensation which can occur in cancer patients treated with radiotherapy. Histopathologic findings include a superficial and deep perivascular lymphohistiocytic infiltration with eosinophils. Most cases have occurred in patients with cervical cancer. To date, only one case of EPPER associated with breast cancer has been reported. We report a case of EPPER in a patient with breast cancer, who presented with eosinophilic, polymorphic, pruritic skin lesions in and around the irradiated left breast.

Familial multiple lipomatosis is a rare hereditary disorder with a proposed autosomal dominant inheritance. Clinically, multiple well-circumscribed, encapsulated lipomas occur on the extremities and trunk. Familial multiple lipomatosis is often confused with multiple symmetric lipomatosis, which is a condition involving a diffuse fatty infiltration around the neck and shoulders. We report two cases of familial multiple lipomatosis with typical clinical features and familial history. To the best of our knowledge, these are the first cases of familial multiple lipomatosis in Korea.

BACKGROUND: Eruptive pseudoangiomatosis (EPA) is a rare, benign, spontaneously regressing childhood exanthem. It is characterized by the sudden onset of several bright red angioma-like papules surrounded by pale halos with a distinct histopathology from true angiomas. OBJECTIVE: This study was performed to evaluate the clinical and histopathologic characteristics of EPA occuring in adults. METHODS: Ten adult patients who visited Pusan National University Hospital and Mok Hye-Soo . Jang Ho-Sun Dermatology Clinic from March 2005 to September 2006 were evaluated. We prospectively evaluated the sex, age, onset season, past medical history including immunosuppressive abnormalities, systemic disorders and other diseases including allergies. We also investigated the relations of mosquito biting, patients' occupations and outdoor activities to occurrence of EPA. In addition, simultaneous occurrence in family members, the clinical, histopathologic, laboratory findings, disease courses and responses to treatment were evaluated. Based on medical records, photographs and pathologic slides, we retrospectively diagnosed another 20 EPA patients suspected as insect bite from October 2003 to March 2005. The same questions were inquired as for the 10 patients who prospectively underwent evaluation. RESULTS: In the study, female predominance (76.7%) was observed and the average age of onset was 54.2 years. Interestingly, there was no child patient during the period of study. Multiple, 2~5 mm sized, red angiomatous papules surrounded by pale halos occurred on exposed areas such as the arms (86.7%), legs (50%), and face (46.7%), although it could also occur to a non-exposed area. EPA occuring in adults usually appeared in summer (80%). The mean disease duration was 3.4 weeks. Although EPA spontaneously regressed, it had the potential of recurrence (46.7%). Histopathologic findings showed dilated dermal blood vessels without the evidence of increase in numbers, and perivascular lymphocytes infiltration. Inside the lumen of dermal blood vessels, plump endothelial cells were found. CONCLUSION: EPA occuring in adults usually happened to exposed sites in summer, so it can be misdiagnosed as insect bite. We suggest that dermatologists should be concerned about EPA in adults and conduct further investigation to have a better understanding of the disease.

Pyoderma gangrenosum is a rare cutaneous disorder composed of chronic recurrent painful ulcers. The variants of pyoderma gangrenosum are classified as ulcerative, pustular, bullous, and vegetative types. Vegetative pyoderma gangrenosum is a very rare variant of pyoderma gangrenosum characterized by a non-painful and not undermined superficial ulcer that has an exophytic and vegetative border. Systemic disease is rarely associated with this variant and the course is usually benign. Furthermore the response of therapy is so good that nonaggressive treatment such as antibiotics or topical steroids are sufficient for complete healing of the lesion. Recently, we were presented with a case of a 71 year old man who had had chronic recurrent cutaneous lesions composed of erythematous vegetative plaques, and superficial ulcers with serous discharge on the suprapubic region, both forearms and thighs. After skin biopsy, a diagnosis of 'vegetative pyoderma gangrenosum' was made. We report this case along with a review of the literature.
