We observed clinical and histopathological findings of porokeratosis in 16 cases which comprised 2 linear types, 4 superficial disseminat:ed forms, 4 disseminated superficial actinic porokeratosis and 6 plaque types. From the observation, the following results were obtained. l. Clinical results 1) Eleven cases were men, 5 cases were women, and the sex ratio was 2. 2 to 1, age distribution was from 6 to 61 years (mean age: 34. 2years), and the distribution of age of onsets was from 2 to 52 years(mean age of onset' 23. lyears). 2) Four cases had family history of porokeratosis, but linear forms did not. 3) Nine cases had pruritus especially, all cases of DSAP and DSP except 1 case complained pruritus. 4) Tmo cases of DSAP had tendency of summer exacerbations. 2. Histopathological results 1) Cornoid lamellae were prominent in all cases of plaque types and linear types, and minimal in all cases of DSAP and DSP except 1 case. 2) Epidermis between the cornoid lamellae were normal or acanthotic in all cases except 1 case of plaque types and linear types, and were atrophic in 5 cases of 8 cases in DSAP and DSP.

BACKGROUND: According to the areas and people that are examined, there are many differences in the prevalence of syphilis in Korea. However, the reactive rate of the serologi test for syphilis showed an increase in the 1960s, and it has deerea@sed from the beginning of the 1970s. OBJECTIVE: Comparing the results of tke serologic test for syphilis which lotad been performed for the 5 years(1987-1991) on the physical examines and pregnant women who were considered as healthy, with the results with normal people, who were considered as healthy, which had been already reported, we tried to observe the change of reactive rate of serologic test for syphili. METHODS: The serologic test for syphilis, including serum VDRL test and serum TPHA test, were carried out on 25,254 healthy adults(20,405 were physical examineea eamined at National Medical Center and 4,849 were pregnant women delivered at National Medical Cer ter). RESULTS: The reaetive rate of serum VDRL test was 0.8% in 25,25 the althy adults(physical examinees 0.8%, pregnant women 0.7%). There were no stistically differerces between the annual incidences. 85.5% of VDRL-reactive subjects showed low VDRL titers(below 1:4) by the quantitative serum VDRL test, The biologic false positive reaction of serum VDRL test was 29(19.5%) in 149 VDRL-reactive subjects, using serum TPHA test as a standard. CONCLUSION: This study suggested thai, there was a decrease in the prevslence of syphilis in Korea.

The skin manifestations of secondary syphilis, termed syphilid, show macular, papular and papulosquamous rashes in most cases, but may show lots of other clinical findings. We report a case of syphitid simulating purpura annulsris telangieitodes in 25-year-old male who had a history of genital ulcer 2 months ago. The skin lesion showed diffuse erythematous, 1-3 cm sized, telangiectatic annular patchea and purpuric plaques on both lower extremities and discrete papulosquamous rashes on both soles. The results of the serologic test for syphili was found to be reactive to 32 dilution in serum VDRL test and positive in serum TPHA test. Histovathologically, we could observe the obscuring of dermoepidermal juction, coat-sleeve-like perivascular infiltrate composed of mononuclear cells and a few plasma cells, and endothelial swellings. Afte the treatment with benzathine penicillin G, the titer of serurn VDRL test was decreased abruptly to 4 dilution and the skin lesions disappeared completely.

A 24-year-old woman was seen for evaluation of an skin lesion on thiright nipple. Examination revealed a solitary 1.5 x 1cm-sized, erythematous, oozing, eroded andruted, verrucous nodule on the right nipple. A small amount of serous discharge was found but there was no pain or tenderness. Histopathologic findings showed cystic invaginations extending down vard from the epidermis and papillary projections extending into the lumina of the invagination. Pupiae were lined by two rows of cells. In stroma, there were marked inflammatory infiltrates containing any plasma cells. The overlying dermis showed an adenomatous growth pattern with a prolifertion of round, oval or irregular shaped ducts and fibrotic stroma.

Stevens-Johnson syndrome (SJS) presents with widespread blisters, erythematous or purpuric macules, and one or more mucous membrane erosions. Various etiologic factors, including infection, vaccination, drug administration, systemic diseases, physical agents, and food have been implicated as causes of SJS. Mycoplasma pneumoniae is the most common infectious agent to cause SJS in children. In recent literature, M. pneumoniae-induced SJS with mucositis that lacks the typical target lesions has been described. We report a case of a 6-year-old boy with swelling, peeling of the lips, and red eyes with photosensitivity. On physical examination, he showed severe oral mucositis and conjunctivitis with no evidence of skin lesions. Mycoplasma antibody, which was positive with titers of more than 1:2,560. For patients presenting with fever and mucositis of unknown origin, M. pneumoniae should be considered.

Hemophilia, a genetically determined disorder, can be divided into hemophilia A and hemophilia B. Hemophilia A, defined as a sex-linked recessive trait hemorrhagic disease of males characterized by a deficiency of factor VIII occurs about seven times more frequently than hemophilia B which is characterized by a deficiency of factor IX. The complications resulting from hemophilia occurs in virtually every system. This paper is concerned with a rare complication of hemophilia, iliacus hematoma with femoral neuropathy. On case of spontaneous hemorrhage of iliacus muscle with femoral neuropathy in hemophilia was decompressed through a small incision with sump drainage under cover of AHF(Anti-hemophilic factor) concentrated plasma cryoperecipitate followed AHF replacement therapy.

BACKGROUND: Dermatophytoses show marked differences in their incidences, distributions, and causative organisms by age, sex, occupations, environmental conditions and geographic distributions. OBJECTIVE: We evaluated the recent distributions of dermatophytes and compared them with the previous reports in Seoul. METHODS: We evaluated the incidences of dermatophytes according to the patient's age and sex, isolated month, and the infection sites with 387 strains of dermatophytes isolated from the various forms of dermatophytoses during the period from August 1985 to July 1991 in Seoul. RESULTS: T. rubrum was the most prevalent dermatophyte in all age groups except the first decade. The incidence of M. canis was high in age groups below 20 years old relatively high incidences of T. mentagrophytes and T. interdigitale in age groups over 30 years old. Dermatophytes were frequently isolated in summer season, but the incidence of M. canis was relatively high in October and December. T. rubrum was the most prevalent dermatophyte from all forms of dermatophytoses except tinea capitis, but the incidence of T. rubrum was relatively low in tinea corporis. The incidence of T. mentagrophytes was relatively high in tinea unguium and tinea manus, and M. canis was isolated only in tinea corporis and tinea capitis. From the cases showing more than two forms of dermatophytoses. T. rubrum was isolated for the most part. CONCLUSION: This study suggested that there was a rise in the cases of t. rubrum infections in Seoul and in recent years the prevalence of M. canis infections has markedly increased but those of E. floccosum and t. mentagrophytes have decreased.

Annals of Dermatology 1995;7(4):332-337
Fusarium species are known as ubiquitous soil saprophytes and human skin comtaminants. Occasionally, however, they have been reported to cause a variety of infections in humans. We report herein a case of cutaneous infection by Fusarium sokmi in a patient with Burger's disease involving his right lower leg. He was treated with itraconazole 200 mg p.o. per day for 5 weeks and the skin lesion resolved without any noticeable side effects. Furthermore, there has been no evidence of recurrence of the disease 9 months after discontinuing the itraconazole. This is the first reported case of cutaneous infection by Fusarium sokmi in a patient with Burger's disease and itraconazole was an effective drug in our case.
