Toxic epidermal necrolysis is a reactive erythema of nonstaphylococcal origin characterized by a scalded appearance of the skin. The TEN is widely regarded as a variant of severe erythema multiforme because of its acute course, its freguent common cause, its freguent overlap with Stevens-Johnson disease, and its histologic identity. I present a case of TEN with severe mucosal involvement resembled Stevens-Johnson disease.

BACKGROUND: In tinea pedis, the response of treatment and prognosis are different according to clinical types. Positivity in KOH mount and causative agent in culture are also different. OBJECTIVE: Our purpose was to evaluate the clinical characteristics and mycologic findings of tinea pedis according to the clinical type. METHODS: A clinical and mycological study was conducted with 97 cases of tinea pedis among out patients examined for 7 months from June 1994 to December 1994 at Yeungnam University Hospital and Catholic Skin Clizic, Taegu, Korea. RESULTS: 1. Age distribution showed patients in their fourth decade to be most common. The ratio of male to female was 1.2: 1. The distribution of patients by clinical type was interdigital type, interdigital combined with hyperkeratotic type, interdigital combined with vesicular type, hyperkeratotic type, and hyperkeratotic combined with vesicular type, in descending order. One to five years was the most comrrion duration of tinea pedis. Duration of tinea pedis was the shortest in the vesicular type, otherwis was longer in hyperkeratotic type. Rate of family history of tinea pedis was 54.6%. The larger the size of family was, the higher the positivity in family history. The rate of coexistent dermatiophytosis with tinea pedis was 39.1%, and tinea unguium was the most common one. 2. The isolated dermatophytis were T. rubrum, 90.7%, T. mentagrophytes, 7.2%, and T. rubrum rnixed with T. mentagrophytes, 2.1%. T. rubrum showed an even distribution in all clinical types of tinea pedis whereas T. mentanophytes was isolated only in the interdigital type, vesicular type, and interdigital combined with vesicular type. T. rubrum mixed with T. mentagrophytes was isolated in the interdigital combine with vesicular type. Distribution of dermatophytes was relatively even arnong the age groups. T. rubrum showed a relatively even distribution in duration of tinea pedis, but T. mentagrophytes was isolated in tinea pedis with shorter duration.

Lichenoid drug eruption is lichenoid skin eruptions caused by certain drugs and compounds, and can be identical or similiar to lichen planus. A 75-year-old woman who had taken antituberculosis medication(INH, ethambutol, rifampin) for 4 months developed pruritic generalized erythematous papular eruptions on the trunk and extremities, alopecia and nail dystropy. Histopathologic findings were hyperkeratosis, hypergranulosis, hyc rophic degenaration of basal layer, band like lymphohistiocytic infiltration in the upper dermis and perivascular lymphohistiocytic infiltration in the deep dermis. She was treated with systemic corticosteroid, and then skin lesion were slightly improved. After termination of antituberculosis medication, skin lesions were markedly improved with residual hyperpigmentation. Alopecia and nail dystrophy were also improved.

Angiosarcoma is a rare malignant vascular tumor of endothelial cell origin, Cutaneous angiosarcoma usually occurs on the scalp and face of the elderly and most frequently in the sixth and seventh decade. We presented a case of angicisarcoma in a 70 year old woman. The patient had a well-demarcated, 3 x 3cm sized, dark brownish-colored, ulcerative nodule on the vertex with hemorrhagic bulla on the right. temporal scalp. Histopathologic examination of the nodule showed a well differentiated tumor with irregular anastomosing scular channels lined by atypical endothelial cells in the dermis and subcutaneous fat. Immunohistochenlical study for factorVlll-related antigen was partially positive in tumor channels. She was treated by wide surgical excision but she expired 5 months after discharge from the hospital.

To ease the convinience of indentification of common dermatophytes in Korea and to check the possibility of diseovering new species not yet reported in Korea, several species of dermatophytes were cultured on potato dextrose agar(PDA) at the room temperature. They were 46 strains isolated from Korea and 6 domestic strains from a foreign country. Gross and microscopic findings of their colonies were examined. The colonial morphology and microscopic appearance were compared with those of the same strains on Sabouraud dextrose agar(SDA) and corn meal agar(CMA). The results were as follows Typical T. rubrum and its varisnts showed characteristic wine red pigmentation which was rapid, diffuse and uniform, typically arrsnged microconidia were better on PDA. T. mentagrophytes showed yellow-brown pigmentation which were more rapid and darker in the center with gradual fading to the periphery. The mscroconidia, grape-like clusters of microconidia and spiral hyphae were seen better on SDA. T. tonsurans showed characteristic mahogsny colored pigmentation, ballooned microconidia and macroconidia which were seen better on PDA, but diffusible pigmentation of agar were present on SDA only. The gross morphology of T. verracosum were similar on PDA and SDA, but macroconidia were seen better on PDA and CMA, and tortuous hyphae with antler-like branching were seen better on SDA. T. rnegninii showed green-brown pigmentation which appeared rapidty and prominently on PDA. T. rubrum-like microconidia were seen better on PDA and CMA, but in SDA only hyphae were seen. The gross morpholgy of M. canis was similar on PDA and SDA, but spindle shaped macroconidia were seen more typically on PDA. The gross morphology and microscopic appearance of M. gypseum were very similar in all three media. M. ferruginenm showed characteristic rust colored pigmentation and bamboo hyphae which were seen more typically on PDA. The gross morphalogy of E floceosum were similar on PDA and SDA, but cluster formation of club shaped macroconidia were seen more prominently on PDA and CMA. These findings suggest that PDA is a mare convincing media t6Cifferentiate among dermatophytes belonging to genus Trichopkyton.

We report a case of kerion celsi caused by Trichophyton verrucosum in a 4-year-old male. He presented painful, tender, indurated, boggy masses discharing pus on the vertex and occiput. Kerion celsi caued by T. verrucosum was diagnosed by the characteristic gross and microscopic findings of the colony on the Sabourauds glucose. agar. The possible source of infection was searched and wq found that he raised the cattles in his house. They had multiple, scaly, whitish plaques on the skin and T. verrucosum was identified from the hairs of the lesions. He had been treated with griseofulvin and prednisolone, and all lesions were cleared leaving partial alopecia in 2 months.

KOH examination is a simple, rapid and diagnostic procedure to confirm dermatophytic infections. It is important to select a proper examination site of the lesion. To determinate the proper examination site of the lesion, mycologic studies were done with multiple specimens collected from the center, margin and out of margin of the ring-shaped dermatophytic skin lesion on the 58 patients. The results were as follows. Positive rate of KOH wet smear was 94.8% at the center and 100% at the margin of the lesions, 22.4% at the 1 cm and 5.2% at the 2 cm out of the lesions. The more hyphae were found in the lesion, the more hyphae were found out of the lesion. Culture was done on the Sabouraud's glucose agar from the highest KOH positive area and the positive culture was 48 strains (82.8%) of 58 patients. These findings suggested that the ring-shaped active margin was the best site to examine mycologic studies.
