A 20-year-old female, who had been treated with topical PUVA therapy for her vitiligo, developed characteristic skin lesions of disseminated superficial artiric porokeratosis(DSAP). All of her three sisters had vitiligo and had been treated with topica PUVA, hut only one developed DSAP lesion. Her mother had had DSAP lesions on expcsec areas for 20 years. DSAP shows an autosomal dominant mode of inheritance, and is charaterized by multiple ciark brownish keratotic papaules surrounded by slightly elevatied order. The exacerbation of the lesion by exposure t.o UV lignt indicates that the regulatingene for DSAP is related to sunlight. 1-lerein we reported a case of DSAP induced by topica] PUVA therapy in one patient during management of familial vitiligo in 3 sisters.

Tubular apocrine adenoma is a rare benign tumor occuring most often on the scalp. We examined a case of a 69-year-old female who had a well demarcated solid nodule on the scalp. Pathol Microscopically, the tumor was composed of lobules of tubular structures. The tumor lobules were surrounded by a stroma of dense fibrous connective tissue. The tubular structures were usually formed of two rows of epithelial cells. In some areas, the widely dilated tubular structures showed papillary projections into the cavities. Some epithelial cells showed liculoma on decapitation secretion into the cystic structure. Problems of differential diagnosis with other adnexal tumors are briefly discussed.

Sebaceous trichofolliculoma is a variant of trichofolliculoma which occurs in the sebaceous areas rich in follicles and is a relatively rare skin tumor. This tumor is a clinically and histologically easy tumor to recognize that is well differentiated. We examined a case of a consists of a 21-year-old female who had a pedunculated nodule on her scalp. Microscopically, the tumor was large, had a centrally located cavity lined by squamous epithelium and radially arranged sebaceous follicles connected to the cavity. No cytological atypia or recurrence after excision was found.

There are several methods for diagnosis of leprosy, including AFB stain, the measurement of PGL-1 (phenolic glycolipid - 1) antigen titer, and DNA-PCR. In this study, we have used the DNA-PCR amplifying the RLEP repetitive sequence. Our result showed that the RLEP primer offered the more sensitive detection and identification of M. leprae DNA in clinical specimens, compared with the other primer, for example, 18-kDa antigen gene. To screen the resistant M. leprae strain of MDT (Multi-Drug Therapy), we have used the TD (Touch-Down) PCR. We arranged and amplified sequences of the genes, folP, rpoB, gyr, 23S rRNA, in M. leprae involved in MDT-resistance, and could obtain the PCR product each gene, simultaneously. This method, based on annealing temperature, was useful to the detection for diagnosis and the screen of MDT-resistant strain of M. leprae, rapidly. Thus, we suggest that the RLEP primer and TD-PCR method are effective in assessing the diagnosis of leprosy and the identification of drug-resistant M. leprae.

A 29-year-old woman complained of a painless, firm nodule with browunish patch on her left cheek for 5 months. She had had undergone a traffic accident 6 months before, and the normally healed wound on her cheek became reddish and infiltrated. A Skin biopsy specirinen obtained from her skin lesion showed a foreign body reaction with histiocytes and numerouse crystalline structures. These particle. were birefringent under polarized light microscopy. Scanning electron microscopy revealed numerous crystalline particles. Energy dispersive x-ray analysis of the crystal revealed a sharp peak representing silia.

OBJECTIVE: Large loop excision of transformation zone(LLETZ) is gaining popularity as an alternative to other ablative or cone methods for the treatment of cervical intraepithelial neoplasia(CIN). The optimal management of CIN after LLETZ, however, remains controversial and the reliable predictors of residual disease after LLETZ have not been consistently identified. This study was performed to identify factors to predict residual disease after LLETZ. METHODS: From August 1993 to July 1995, 133 patients who received subsequent hysterectomy after LLETZ in Department of Obstetrics and Gynecology at Seoul National University Hospital were retrospectively reviewed. Residual disease was defined as positive findings of CIN or further advanced findings in hysterectomy specimen. The age of patients, the severity of disease and the status of resection margin(RM) were analyzed for predictive values of residual disease. The Chi-square test, Fisher's exact test and Student t-test were used for statistical analysis. RESULTS: The residual disease after hysterectomy was negative in 85.7%(114/133) and positive in 14.3%(19/133). Among 19 cases with positive residual disease, 3 cases were revealed to be microinvasive cervical cancer. The mean age of patients with no residual disease was 42.5 years(range; 27-71) and that of patients with residual disease was 49.1 years(range; 33-72). Nine out of 94 cases(9.6%) with negative RM and 10 out of 39 cases(25.6%) with positive RM in LLETZ had residual disease. Two out of 14 cases(14.3%) with CIN II and 17 out of 119 cases(14.3%) with CIN III in LLETZ had residual disease. The success of LLETZ which means no residual disease was influenced by the age of patients(p=0.005) and the status of resection margin of LLETZ(p=0.032). CONCLUSION: The negative resection margin in LLETZ does not always guarantee that there is no residual disease. Close preoperative workup and more aggressive treatment plan(wide conization or hysterectomy) should be considered in patients who has higher possibility of positive residual disease such as old age and positive resection margin in LLETZ.

The method of cell lysate preparation of M. leprae is an important technique in the study of leprosy. This report describes the optimization of method for cell lysate preparation of M. leprae obtained from infected nude mouse. After M. leprae isolated from nude mouse foot-pad was disrupted by sonication, it was centrifuged and then whole lysate was prepared. With this method it was possible to isolate 0.3 mg whole cell lysate using 20 mg of M. leprae. By SDS-PAGE and Coomassie blue staining, the number of protein in M. leprae is less than that of other bacteria, for example, E. coli and M. smegmatis. It is likely that this is due to the small genome size. This work will contribute to the analysis of new protein antigen of M. leprae and the basic study for the development of vaccine in leprosy.

This study is undertaken to investigate the clinical effecte of Neutrogin(recornbinant human granulocyte-colony stimulatiing factor) in 25 patients with ovarian caneer who received two courses of CAP chemotherapy. In the first courae of chemotherapy as a contml course, all patients were treated with CAP chemotherapy alone and during the second course, Neutrogin was given at a dose of 2ug/kg/day subcutaneouely for 14 days 24 hours after completion of chemotherapy. Neutrogin significantly increaaed the nadir count of leukocyte and abaolute neutrophil and decreased tbe number of days per patient on which the absolute neutrophil count was 1,000/mm3 or less. The mean recovery time required for neutrophil to greater than l,500/mm3 after nadir were significantliy decreased in the seeond comse as compared with the first course. Each one patient exriened mild side effects of Neatrogin, such as fever, tene pain and malaise and rernovered without tretment. These results showed that Neutrogin is extremely effective and useful to treat chemotherapy indueed leukopenia and to accelerate the recovery from these complications.

Recently, many reports suggest that the activation of Toll-like receptor 2 (TLR2) by microbial lipoproteins may initiate innate defense mechanism against infectious pathogens. Especially, TLR2 is critical in the immune response to mycobacterial infections and the mutations in the TLR2 have been shown to confer the susceptibility to severe infection with mycobacteria. A previous study reported that there is a mutation of TLR2 (TLR2-R677W) in lepromatous leprosy. In this study, thus, we performed the functional study on TLR2 by measurement of IL-12 production in serum and monocytes from leprosy patients with TLR2 mutation (R677W) to verify the relation between TLR2 and the susceptibility to leprosy. Tuberculoid leprosy patients showed higher serum levels of IL-12p70 compared with those of lepromatous leprosy. In contrast with the lepromatous leprosy patient with TLR2 mutation, especially, the group with wild-type TLR2 showed 2-fold increase levels of IL-12p70. Functional studies demonstrated that monocytes from patient with the TLR2 mutation, in comparison to the wild-type TLR2, is significantly less responsive to Mycobacterium leprae lysate. Our results reveal that TLR2 has a important role in the IL-12 production from monocytes and the susceptibility of lepromatous leprosy.
