BACKGROUND: UVB is responsible for most of the carcinogenic effects of sun exposure. OBJECTIVE: Aim of this study was to investigate the regulation and intracellular redistribution of p53 protein after UVB irradiation. METHODS: Cultured normal human melanocytes and G361 melanoma cells were used for west-ern blotting and confocal microscopic examination for determining expression and distribution of p53. RESULTS: UVB irradiation increased p53 expression in cultured normal human melanocytes and G361 malignant melanoma cells according to increasing doses of UVB. Furthermore, p53 moved from cytosol to nucleus after UVB irradiation. CONCLUSIONS: UVB irradiation induced overexpression and redistribution of p53 in cultured normal human melanocytes and G361 malignant melanoma cells.

In about 20 to 30 percent of cases with organoid nevus (nevus sebaceus), benign and/or ma-al lignant tumors of the epidermis and adnexae may develop. We describe a 71-year-old woman with sebaceous carcinoma and basal cell epithelioma developed in organoid nevus.

Cutaneous metastasis from parotid gland carcinoma is very rare and there have been no re-ports in Korean literatures. Furthermore, it can often manifest as inflammatory type of skin metastasis and mimic a radiodermatitis. We report a case of a 31-year-old Korean man with cutaneous metastasis originated from parotid gland mucoepidermoid carcoinoma which mimicked clinically a radiodermatitis.

Purpura fulminans may be seen in three different clinical settings: (1) in the neonatal period from protein C and S deficiencies, (2) during severe bacterial infections such as “sepsis-associated” purpura fulminans, and (3) during the convalescence of an otherwise benign “preparatory” infectious disease most commonly involving the skin. We report a case of a 20-month-old male child with purpura fulminans as a presenting sign of disseminated intravascular coagulopathy (DIC). He had suffered from fever of unknown origin for a month. Although purpura fulminans is not a common disorder to dermatologists, the awareness of this disorder may be the clue to diagnose and treat underlying diseases.

Intravascular fasciitis (IVF), a rare distinct variant of nodular fasciitis, possesses the same clinical and histologcal features of nodular fasciitis, but in addition, involves predominantly small to medium- sized veins and/or arteries intraluminally, intramurally and extramurally. Only 3 cases of intraoral IVF have been reported in the English literature. Herein we report a case of IVF developing on the inner lower lip and it was successfully treated with simple excision.

BACKGROUND: The hypereosinophilic syndrome(HES) represents a leukoproliferative process likely caused by a number of disorders, all of which are marked by sustained over-production of eosinophils. OBJECTIVES: The purposes of this study were aimed at evaluating the clinical and histopathological characteristics of HES. METHODS: The medical records and hist opathological slides of patients with HES who had skin biopsies performed in our department were reviewed. Criteria for the diagnosis of HES include (1) peripheral blood eosinophilia with eosinophil counts greater than 1,500/L for at least 6 months; (2) no evidence of parasitic, allergic, or other known causes of eosinophilia; and (3) presumptive signs and symptoms of multiple organ involvement. RESULTS: Four male and three female patients were included. HES developed in adulthood or old age (mean, 43.4 years). Because only the patients with cutaneous involvement were included, all the patients showed skin lesions. Heart, liver, stomach, nervous system, lymph nodes, and lung were involved organs in decreasing order of frequency. At the onset of HES, 40 to 80% of white blood cells were eosinophils in peripheral blood. White blood cell count and serum IgE level were elevated in all the tested patients. In six patients (85.7%), the level of serum erythrocyte sedimentation rate was elevated. Persistent hypereosinophilia (>1,500/L) was present for longer than 6 months in all patients. Stool examination and skin test for parasitic infestation all gave negative results. All the patients were not taking any medication. Histopathological examinations revealed perivascular mixed inflammatory cell infiltration; predominantly eosinophils in the stomach, liver, and nerve as well as in the skin. Interestingly, two patients who were presented with skin lesions showed the findings of eosinophilic vasculitis. In these patients, the skin lesions were consisted of Raynaud's phenomenon, digital gangrene, and several erythematous plaques. The most common cutaneous manifestations were papules and nodules on the extremities. The main treatment modality was systemic steroid. Except for one patient presented with central nervous system involvement of HES, all the patients were in a well-controlled state. In one patient with the typical clinical and hematologic features of HES, Hodgkin's disease followed. After the complete remission of Hodgkin's disease with chemotherapy, HES subsided. CONCLUSIONS: HES is a heterogenous collection of disorders marked by hypereosinophilia and organ damage. Most common cutaneous manifestations were papules and nodules on the extremities. Raynaud's phenomenon and digital gangrene can be the primary manifestation of HES in which cases cutaneous lesions showed eosinophilic vasculitis. Five patients (71%) responded well to systemic steroids. HES may be a herald of malignancy such as Hodgkin's disease. Further investigation will be mandatory ro elucidate the etiology and pathogenesis of HES.

Laugier-Hunziker syndrone is a rare, pigmentary disorder of the lips, oral mucosa, and nails. The absence of intestinal polyposis differentiated it from Peutz-Jeghers syndrome. We describe a 16-year-old boy with multiple, brownish, lenticular macules on the lips, oral mucosa, perianal area and anal mucosa, and on the digits of his fingers and toes, in wham intestinal polyposis was not detectable.

OBJECTIVE: The HPV vaccination target adolescents, and may be influenced by opinion of parents and other family member. For implementation of HPV vaccine, we measured knowledge of HPV infection and acceptability of vaccination among adults in Korea. METHODS: From August 2006 to November 2007, we provided a written questionnaire to females (above 19 years- olds) who visited Il-sin Christian hospital for prenatal care or gynecological examination. The questionnaire was built using elements of The Health Belief Model. We measured (1) awareness of HPV (2) perceived susceptibility (3) perceived seriousness (4) perceived benefit of vaccination (5) perceived barriers (6) cues to action. RESULTS: Total 975 females answered the questionnaire, and the mean age was 40 years. Only 23.8% knew the fact cervical cancer is related to HPV infection. 78.3% of respondents were willing to accept HPV vaccination after they understood HPV vaccination can prevent cervical cancer. Financial burden and possible side effect were barriers to vaccination. CONCLUSIONS: Despite of low awareness of HPV infection, most (78.3%) adults favored having HPV vaccination. But the vaccine was more likely to be accepted if it is recommended by a physician and reasonably priced.

We report a case of cutaneous metastasis of thymic carcinoma in Korean. A 44-year-old female, who had been diagnosed as thymic carcinoma and treated with total thymectomy and post-operative radiation therapy, presented grouped erythematous papules on the left chest. CT scans revealed metastatic lesions in the left pleura and abdominal cavity. Histopathologic examination of skin biopsy showed extensive infiltration of malignant cells in dermis and subcutis. The morphology of infiltrating cells was similar to that of tumor cells from primary thymic carcinoma specimen. The results of immunohistochemical study for skin biopsy were consistent with the features of non-neuroendocrine thymic carcinoma. Histopathologic and immunohistopathologic similarity between cutaneous lesion and previous tumor suggested that malignant cells in the skin lesion could originate from progressing thymic carcinoma.
