Cutaneous larva migrans(CLM) is a creeping cutaneous eruption that results from skin invasion by the larval form of nematodes. We experienced two patients who had typical clinical findings of CLM. One patient had a history of contact with possibly contaminated fertilizer by the larva of nematotes. The other had a history of travelling to the endemic tropical areas. We report herein two cases of CLM with the literature review of the previous CLM cases in Korea.

BACKGROUND: Skin cancer is one of the most preventable cancers by sun-protection and sunscreen is the most commonly used method of sun protection. OBJECTIVES: The aim of this study is to evaluate the awareness of harmful effects of sun exposure and behavior of sunscreen use in Korean. METHODS: One thousand, two hundred and seventy-four subjects who visited Dermatology Department at Asan Medical Center between April and July 2000 were interviewed. The questionnaire provided information about demographic characteristics, daily sun-exposure time, and sunburn history in the year before. It also included the questions about the causes of wrinkle, sunspot, chloasma, and skin cancer, as the awareness of the harmful effects of sun exposure. The use of sunscreen or other sun-protective methods, and the knowledge about sun protection factor (SPF) were also reported. RESULTS: The harmful effects of the sun in causing wrinkle, sunspot, chloasma, and skin cancer were conceived by 11.1%, 24.4%, 41.4%, and 44.3% of the respondents respectively. Thirty nine percent of the respondents used sunscreens, and the other 61% hardly knew necessity of sunscreens. Those who understood the meaning of sun protection factor(SPF) were 23.7%. Sun-protective methods except using sunscreens were use of a hat or a cap(53.2%), long-sleeved clothing(27.2%), a parasol(27.0%), heavy make-up(11.2%), and a towel(3.8%). Male respondents, people who were younger than 20 or older than 70, and those who had not sunburned the year before were less likely to use sunscreens. CONCLUSION: The results indicate an urgent need for education about the harmfulness of sun exposure as well as benefits of sunscreens.

BACKGROUND: Xanthelasma palpebrarum is the most common cutaneous xanthoma. Although xanthelasma is a type of xanthoma, a half of patients in most series are known to be normolipemic. OBJECTIVE: This study is an attempt to elucidate the clinical and pathologic features of xanthelasma in Korea and to know the clinical significance of xanthelasma, especially suggested role as a marker for hyperlipidemiae and increased risk for cardiovascular diseases. METHOD: Thirty seven cases of xanthelasma were clinially and pathologically analyzed. Incidence of abnomal lipid profiles and cardivascular diseases were compared with those of control group using logistic regression statistics. RESULTS: 1. The incidence of xanthelasma was 0.09% of the total number of dermatologic patients. 2. The ratio between male and female was 1: 1.8 and the mean age was 52.4 years (range;17-71 years). 3. Clinically, it typically presented as yellow or orange papules on the inner canthus of both upper eyelids. 4. The incidences of abnormal lipid profiles(hyperlipidemia and dyslipoproteinemia) are 42.4-44.0%. The levels of total cholesterol and low density lipoprotein-cholesterol were increased significantly. The incidence of the cardiovascular diseases was 16.2%, which was not statistically different from that of control group. 5. Histopathologic findings of 23 cases showed masses of foam cells in the upper dermis accompanied with sparse inflammatory cells and few giant cells. CONCLUSION: Xanthelasma seems to help to identify persons with abnormal lipid profiles which are risk factors of cardiovascular diseases and we recommand examination of lipid profiles in patients with xanthelasma.

Aquired fibrokeratoma is a rare, benign tumor which occurs most frequently on the fingers. Because of the digital predilection, a term of digital fibrokeratoma has been frequently used. We present here two cases of acquired fibrokeratoma occurring on the prepatellar area and the proximal nail bed which are unusual sites of this lesion. A skin-colored, hyperkeratotic tumor with finger-like projection was found on the prepatellar area of a 29-year-old man and a round pedunculated nodule was found on the proximal nail bed of second finger of a 74-year-old woman. Histopathologic examination revealed typical features of acquired fibrokeratoma.

Mucormycosis is a rare and opportunistic infection usually associated with hematologic diseases, diabetes mellitus, renal failure, solid tumors, and organ transplantations. We present here a considered case of disseminated mucormycosis in renal transplant recipient. A 60-year-old man who had undergone second kidney transplantation for a month visited emergency room due to 5 day history of cough with spiking fever and abnormal mental status and vital signs were rapidly deteriorated. Septic shock was suspicious. He was admitted to ICU and treated with broad spectrum antibiotics and antiviral agents, but there was no improvement. A few days later, several large hemorrhagic blisters and purpura occurred on the face, trunk, and both lower extremities. The histopathologic examination from skin specimen revealed large, broad, nonseptate hyphae branched at right angles in the dermis and blood vessels, which was consistent with mucormycosis. But the skin culture for fungus was negative. He had had no skin trauma history and evidence. So we considered the disseminated mucormycosis from unknown primary origin. He died of progressive respiratory failure before antifungal treatment.

BACKGROUND: Onychomycosis and tinea pedis are common superficial fungal infections. Causative organism in onychomycosis and tinea pedis have been extensively studied, but the pathogenic role of non-dermatophyte is still controversial. Trichosporon species are soil and water-inhabiting yeasts, and occasionally found in the normal flora of human skin, mouth, and nails. Trichosporon spp. have been reported to be one of the pathogens in onychomycosis and tinea pedis. OBJECTIVE: We performed mycologic studies to investigate the prevalence and significance of trichosporon spp. in skin and nail lesions, which were clinically suspected of onychomycosis and tinea pedis. METHOD: We performed a survey of the mycologic laboratory records of patients clinically suspected of onychomycosis and tinea pedis from August 2001 to July 2002, and tried to identify trichosporon to species level by using API 20C kit systems. RESULTS: Out of total 1509 nail and skin samples examined, 663(43.9%) were culture positive. Trichosporon spp. were recovered from 11.2%(74/663) of the samples. In onychomycosis considered alone, the prevalence of solitary isolated Trichosporon spp. was 7.7%. In species level, T. asahii(62.1%), T. mucoides(20.3%), and T. inkin(14.9%) were isolated in decreasing frequency. The positive rate for KOH examination in trichosporon spp. was 52.9%. Among the isolated trichosporon spp., mixed cultures with other organisms were 13(17.6%) and solitary isolates were 61(82.4%). 31(41.9%) were not only positive for KOH examination but also founded in pure culture in relatively large colony counts. In pure culture isolations, high colony counts predominated over mixed cultures. CONCLUSION: Trichosporon spp. is a relatively common isolates from fungal cultures of skin and nail, and it may be pathogenic in some cases of skin or nail infection.

BACKGROUND: Scleredema is a rare connective disorder with unknown etiology. There were no comprehensive studies about the clinical and histopathological features of scleredema in Korea. OBJECTIVE: Our purpose was to find the clinical and pathological features of scleredema. METHODS: The 31 patients with scleredema at our institution over ten years were retrieved. We reviewed medical records, clinical photographs, and histopathology slides of these patients, retrospectively. RESULTS: 1. The male to female ratio was 23:8 (2.9:1). 2. Most of the patients had the insidious onset and chronic localized lesion on the nape and upper back. 3. In sixteen patients (16/31, 51.6%), the diabetes mellitus was accompanied. In these patients, the male predominance (14/16, 87.5%) was significant. 4. The positive staining was in 75%(15/20) of the tissues with alcian blue or mucicarmine staining. 5. In four patients, localized electron beam therapy markedly improved the skin lesion without serious adverse effects. CONCLUSION: A preceding respiratory infection was uncommon. Almost all patients had insidious onset and chronic course. Diabetes mellitus was commonly accompanied, especially in male patients. Electron beam therapy appears to be effective in the treatment of scleredema.

Cutaneous pseudolymphoma (CPL) has a microscopic appearance that resembles that of cutaneous lymphoma, but shows a clinically benign course. The differential diagnosis of CPL with cutaneous lymphoma is very important because clinical outcomes of them are quite different. We herein describe two cases of B-cell pseudolymphoma, which were difficult to differentiate from cutaneous B-cell lymphlma. All of two cases, Polymerase chain reaction of immunoglobulin heavy chain gene rearrangement showed polyclonal pattern.

Neutrophilic eccrine hidradenitis (NEH) is a rare neutrophilic dermatosis which is characterized by the erythematous papules or plaques with a neutrophilic infiltrates around eccrine glands and coils. In 90% of cases, NEH develops in patients who have received chemotherapy for malignant diseases, but other drugs, infections, and paraneoplastic phenomenons are considered as possible etiologic factors. Furthermore, NEH is known to be extremely rare in infants. Herein we report a case of NEH in nine-month-old infant with acute myelogenous leukemia (AML), which lesions appeared on the extremities including palms and soles before starting chemotherapy.

Lichen sclerosus et atrophicus is a benign, chronic inflammatory dermatosis with multifactorial origin. It is most common in the vulvar and perianal areas, but it may involve any other area, rarely face, oral mucosa, and palm and sole. Especially, lichen sclerosus et atrophicus on face is more difficult in diagnosis due to atypical location and may be confused with morphea, discoid lupus erythematosus, vitiligo, and atophic scar. We, herein, present a case of facial lichen sclerosus et atrophicus with central brownish atrophic change in a 21-year-old man. The lesion showed atypical clinical feature and unusual location. But histologic examination revealed typical features of lichen sclerosus et atrophicus.
