We report a case of hereditary trichilemmal cyst with proliferating trichilemmal tumor in a 64-year-oid man, who has generalized 157, variable sized firm cutaneous nodules for 40 years. The cystic nodules are chiefly located on the scalp and trunk which showed characteristic histopathologieal findings of trichilemmal cyst and proliferating trichilemmal tumors. His son also has multiple trichilemmal cysts and his mother seems to have had clinically similar lesions. The patient and his son were treated with surgical excision and therapeutic trial of oral isotretinoin for 2 months. Isotretionoin was ineffective in the patient, but the lesions of his son were decreased in size.

We reviewed the clinical features and the skin biopsy slides of 27 patients who were diagnosed as PLEVA clinically or histapathologically in order to evaluate the clinical characteristics and the specific histopathological findings of PLEVA. The results were as follows : l. 13 of these 27 cases(48%) were confirmed as PLEVA. 2. PLEVA was more frequent in males(85% ), most of whom were young adults. 3. In most cases of PLEVA, the predilection site was on the trunk and extremities, and mild pruritus was a characteristic complaint. 4. Most cases of PLEVA were treated with tetracycline or PUVA therapy with temporary remission, but this therapy did not decrease the rate of recurrence. 5. Some histopathological findings previously described as typical in PLEVA(eg, trapped RBC in the epidermis, exocytosis of lymphocyte, dermal hernorrhage and lymphocytic perivasculitis) seemed not to be specific and were often seen in a variety of other dermatoses. 6. The histopathological findings of linear parakeratosis(85%) and dyskeratotic cells in the middle and upper epidermis(92% ) seemed to be significant findings for PLEUA. 7. The above mentioned histopat,hological findings for PLEVA were frequently found from the vesicular lesions or necrotic hemorrhagic papules.

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 clinical and mycological investigation was made with 68 cases of tinea corporis who had visited the Dermatologic Clinic of N.M.C. from Nov. 1985 to Oct. 1988. The results were as follows : 1. The ratio of male to female was 1.1: 1, and tinea corporis was most preva lent in the twenties. 2. 25 cases (36.8%) had a history of contact with infected animals or soil. 3. 75% of cases had less than 2 lesions. The exposed area was more frequently affected, and the face being the most frequent site. 4, Concurrent infection of tinea corporis with other types of dermatophytosis were noted in 33 cases (48.8%), and the most common was tinea pedis. 5. From the 68 cases, 49 organisms composed of 4 species were isolated, which were T. rubrum (32 cases), M. Canis (11 cases), T. mentagrophytes (5 cases) and M. gypseem (1 case). 6. Of the clinical variants of tinea corporis, the annular type was most comm only noted. No species specificity was noted in annular type, but T. rubrum was the major causative organism of eczematous and plaque type, and M. canis was the only isolated organism in herpetiform type. 7. As compared with other dermatophytes, M. canis was more commonly isolated from the smaller lesion.

Prurigo nodularis is a troublesome chronic dermatosis that showed unsatisfactory response to conventional therapies. Since thalidomide has been applied to the treatment of prurigo nodularis, although the action mechanism is still uncertain, many dermatologists have confirmed its effectiveness. We treated a 54-year-old male patient who had prurigo nodularis affecting the whole body for 10 years with 100 to 300mg of thalidomide daily as the sole therapy for 4 months. The skin lesions were flattened leaving postinflammatory hyperpigmentation and the pruritus also sub-sided. Two years after stopping thalidomide, no recurrence was observed.

The prevalence of dermographism in 96 patients of acute or chronic urticaria was studied using dermographic tester. The results were summarized as follows : 1. The prevalence rate of dermographism in acute or chronic urticaria was 26.0% (25/96). 2. Dermographism was more common in acute or chronic urticaria than in the general population(p<0.005). 3. There was no significant difference in the prevalence rate of dermographiam between acute and chronic urticaria. 4. The prevalence rate of dermographism was not significantly correlated with the level of serum IgE.

BACKGROUND: The differentiation of syphilids from other skin decreases is frequently difficult due to considerable variations of clinical and histologic pattern. The most common histologic changes in secondary syphilis are swelling & proliferation of endothelial cells and the presence of a perivascular infiltrate containing plasmia cells. But often, these findings are absert or inconspicuous. OBJECTIVE: We examined the histopathologic findings of secondary syphilis in relation to the clinical types of the skin lesion. MEHTODS: 36 biopsy specimens from twenty-nine serologically and clinically confirmed cases of secondary syphilis (15 macules, 8 papules, 2 condylomata latas and 11 papulosquamous lesions) were examined. RESULTS: The histopath,ologic findings of secondary syphilis showed comparative differences according to the clinical types of the skin lesion. The plasms cell infltrates were absent or sparse in 14 csses(39%) and the plasma cell infiltration was significantly correhted with the age of skin lesions(p=0.02197). Vascular changes were seen in 32 cases (89%), but the incidence of endothelial proliferation was less(25%). CONCLUSION: This study demonstrates the histopathologic findirigs of secondary syphilis in accordance to the clinical morphology of the eruption and thus, help to differentiate syphilids from other skin diseases.

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.
