Dyschromatosis universalis hereditaria is a rare pigmentary disorder characterized by widespread mothed hyperpigmentation and hypopigmentation. We report a 40-year-old male patient with numerous hyperpigmenter, and hypopigmented macules all over the body except on the palms and soles. The family history revealed similar pigmentary changes in 5 other members through 4 generations, and we could guess the hereditary pattern of the disease of this family to be autosomal dominant inheritance.

Beckground : A presumptive diagnosis of cutaneous tuberuisis can be made on the basis of patients history, clinical and histologic findings. However, isolation of Mycabecterum tuberculosis is required for a defimitive diagnosis and confirmation carke difficult with traditional techniques, including the direct visoalization in tissue and growth culture. Objective : We used polymerase chain reaction(PCR) for the detection of mycobacterial DNA from routinely prepared formalin-fixed, paraffin-embedded skin specimens to evaluate its usefulness as a diagnrstic tool Method : We studied typical cases of localized cutaneous rerculosis. Ten paraffin-embedded biopsy samples obtained from 2 patients with scrofulo lupus vulgaris and tuberculosis verrucosa cutis were analyzed by PCR, respectively. Result : M. tubereuloeis DNA was demonstrated in all 10 specimens. Cenclusion : This study shows that the PCR will be a useful method for the confirmation of the diagnosis in localizeted cutaneous tuberculosis and many sl in lesions thought to be related fo tuberculosia infection.

Cerebriform intradermal melanocytic nevus is a cause of cutis veticis gyrata, a morphologic term which describes the hypertrophy and folding of the skin, typically occurring on the scslp, to present a gyrate or cerebriform appearance. We report a 37-year-old woman with a 17 x 22cm soft, convoluted mass over most of the occipital, parietal, and temporal scalp. At birth, she had a small brownish macide on the occipital scalp that enlarged to form this extensive lesion. Histologically, nests of nevus cells were shown in the upper and the mid dermis.

Sensitivity to estrogen has been described previously. The clinical picture is varied with pruritus, either generalized or localized or as urticaria. The hallmark of estrogen dermatitis is the cyclic premenstrual flare. The patient reported here had cyclic erythema multiforme-like lesions and showed a positive intradermal skin test to estrogen. A 20-year-old female patient presented with a periodic 5 year duration of skin lesions on both hands. The eruption commenced in the second half of the menstrual cycle, worsened through the luteal phase but the lesion almost disappeared during menstruation. An intradermal skin test to estrone showed positive results. However, a skin test with medroxyprogesterone acetate was negative. After systemic steroid and antihistamine therapy, the lesions were found to be significantly improved.

Although the incidence of tuberculosis has recently been reduced owing to advance of antituberculous drugs, improvement of public health, and early diagnosis with effective treatment, tuberculosis still remains as a major cause of death in Korea. In general, abdominal tuberculosis is described in three main forms; tuberculous peritonitis, gastrointestinal tuberculosis, and a combination of both. The diagnosis of abdominal tuberculosis, especially extraintestinal tuberculosis, is difficult due to vague symptoms and nonspecific laboratory findings. We experienced an interesting and unique case of abdominal tuberculosis. A 27-year-old man who complained of symmetric diffuse abdominal distension revealed a huge cystic mass. After cystectomy, the mass was confirmed as tuberculous cyst involving surrounding organs such as the spleen, pancreas, liver, and transverse colon. His postoperative course has been good since the start of antituberculous medication. The authors have experienced a case of abdominal tuberculosis mimicking cystic mass and report the case with the brief review of literatures.

Background: PUVA has been used effectively in the treat,ment of vitiligo, but the mechanism by which PUVA stimulat.es melanocyte proliferation in vitiligo is not known. Several mechanisms have been suggested to be involved in the process of repigmentation of vitiligo. First, UV light, with or without psoralen, directly stimulates the proliferation of melanocytes. Secondly, PUVA may act. on epidermal keratinocytes or dermal components to stimulate t,hem to release certain melanocyte growth st,inulation factors that enhance the proliferation of melanocytes in depigmented lesions. Thirdly, PUVA irnmunologically leads to the impairment of epidermal Langerhans cell function and alteration of circulating T and B cell function, which results in the suppression of the stimuli is for rnelanocyte destruction during the therapy. Objective : To test, th hypothesis that PUVA induced repigmentation in vitiligo results from the stimulation of growth factors that induce melanocyte proliferation, and that PUVA may suppress the immune reacticin to melanocytes, especially in autoantibody synt,hesis, we examined the effects of sera on the growth of epidermal melanocytes and control cells, and t,he incidence of antibodies to melanocyte and melanoma cells(SK-Mel 2~3) in the sera of patients with vitiligo. We also had normal control individuals and studied the changes of the antibody titer in the sera of patients with vitiligo. Methods : The rate of H thymidine uptake was estimat,ed in cultured melanocytes and fibroblasts t,reated by patients sera before and after PUVA treatment. SDS-PAGE and immunoblotting analysis were used to idcntify anti pigment cell autoantibodies and were compared to the titers of autoantibodies after PUVA. Results : 1. Melanocyte and fibrablast proliferation was increased by PUVA treated sera. Their proliferation was in proportion to the duration of the PUVA treatment. Melanocytes proliferated more than fibroblasts. 2. Significant differences between vitiligo patients and normal controls were found in the inci dence of anti-pigment cell antibodies. The antibodies were predominantly directed to melanocyte antigens of 110 kD, 65 kD, 45 kD and melanoma cell antigens of 110 kD, 103 kD, 88kD, 70 kD, 56 kD, 41 kD. 3. The titer of anti piment cell antibodies showed a tendency to decrease after PUVA treat- ment in most patients regardless of clinical improvement. Conclusion ; PUVA treated sera induced proliferation of melanocytes and fibroblasts and the production of aut,oantibodies was suppressed against pigment cell antigens through irnmunosuppression, which might help in the repigmentation of vitiligo.

Background: It is important to understand the morphologic characteristics for the identification of a microorganism. Electron microscopy has contributed a great deal to the field of mycology. Scanning electron microscope(SEM) has become a useful tool to study three-dimensional images of fungi. Vacuum dessicator aqueous fixation is useful sample preparation technique for SEM examination of fungal specimens without surface distortions. Objective : This study was done to observe the three-dimensional structures of dermatophytes preserving their natural growth characteristics. Methods : Trichophyton rubrum, T. mentagrophytes, Microsporum canis, M. gypseum, and Epidermophyton floccosum were isolated and cultured on Sabouraud agar, corn meal agar, or rice agar plate. Vacuum dessicator aqueous fixation was utilized as a preparation technique for SEM examinations of the fungi. Results : Vacuum dessicator aqueous fixation led us to examine the aerial mycelia including conidia of the dermatophytes under SEM. The five species of dermatophytes showed their own characteristic structures especially on microconidia and macroconidia. Conclusion : The use of ultrastructural research has made it possible to identify the species of fungi and can be expaned and improved along with the development of SEM and specimen preparation techniques.
