We report herein a case of lymphomatoid papulosis in a 23-year-old female who had recurrent erythematous pinhead to pea sized papules and nodules on the both inner thighs and forearms for 4 years. Some lesions showed central hemorrhagic necrosis or scale formation. Individual lesions persisted for several months and showed spontaneous regression leaving pigmentation or depigmented atrophic scar. Histopathologically, there was marked cell infiltration, especially in the dermoepiderrnal junction and perivascular area. Infiltraled cells consisted of sorne ncutrophils and numerous atypical cells that had variable sized and irregular shaped nuclei. Electronmicroscopically, some atypical cells had cerebriform nuclei with marked peripheral condensation of chromatin and cytoplasm contained a few organelles, many polyribosomes and some dense bodies.

This study was designed to investigate the effect of local hyperthermia on contact hypersensitivity (CHS) and elucidate it's mechanism through assessment of number of epidermal LCs and transfer of spleen cells. Depilated dorsal skin of mouse was immersed into controlled water bath at 52 ℃ for 30 seconds in vivo. The number of epidermal LCs was counted by adenosine triphosphate staining, and CHS to 2,4-dinitro-l-fluorobenzene was assessed by ear swelling and transfer of spleen cells. The number of LCs was significantly reduced 1 to 3 days after the hyperthermia treatment and recovered to normal 5 days after the treatment. CHS was significantly suppressed in mice sensitized 5,7, or 10 days after hyperthermia treatment, but the suppression was meager in mice sensitized 1 or 3 days after the treatment. There is a discord between the number of LCs and degree of CHS. When mice received spleen cells from hyporesponsive donors, CHS was remarkably sup-pressed in the recipient mice compared with positive control. These findings suggest that tfeatment of local hyperthermia suppress CHS in mice, which may be associated with the induction of suppressor cells. The nature of the discord between the the number of LCs and degree of CHS in this investigation remains to be cleared by further studies.

Male breast cancer is a rare disease, representing approximately 1% of breast cancer and less than 1.5% of malignant tumors occurring in men. We report a case of cuaneous metastasis of male breast cances. a 64-year-old male who presented with multiple nodules and erythematous plaque on the right anterior chest and enlargement of the right axillary lymplinodes. The histopathologic findings of the nodule showed atypical tumor cells with a somew eat gland-like pattern. The cells showed potive reactions in PAS, DPAS and alcian blue stains, and also positive for estrogen and roiesterone receptors. Biopsy specimens taken from the plaque showed cellular arrangement in show line, referred to as Indian filing, between thiclenecin collagen bundles. He was treated not, tamoxifen, 5-fluorouracil, adriamycin, cyclophosphamide and megestrol acetate. 5 months after nitiation of the treatment, the skin lesions were improved vvith a decreased number and size or dules and decreased intensity of erythema.

We report an extremely rare case in which two tuberculids, papulonecrotic tuberculid and erythema nodosum, occurred together. A 16-year-old girl had two types of clinically distinct lesions; asymptomatic necrotic papules on the upper and lower extremities and painful subcutaneous nodules on the legs. A Mantoux test showed a strong positive reaction. Histopathologic findings of the necrotic papule and subcutaneous nodule were consistent with papulonecrotic tuberculid and erythema nodosum, respectively. There was no extracutaneous focus of tuberculosis. Polymerase chain reaction for tuberculous bacilli in the papulonecrotic tuberculid lesion revealed a negative result. Antituberculous therapy brought a rapid clinical improvement of both lesions.

A 31-year-old woman had a livedo reticularis of reticulated, bluish discoloration on both arms and legs for 18 months with a burning pain in the right hand and numbness in both lower legs. The findings of the electromyography were consistent with mononeuropathy multiplex and bilateral ulnar-median nerve anastomosis. A biopsy specimen from the right sural nerve showed perivascular lymphocytic infiltration and occasional myelin digestion chambers, which were consistent with vasculitic neuropathy. We present a patient with livedo reticularis idiopathica associated with mononeuropathy multiplex syndrome who also has bilateral ulnar-median nerve anastomosis.

We report a case of multiple Bowen's disease associated with leprosy. A 68-year-old man was seen because of slightly pruritic multiple erythematous scaly patches and plaques on the trunk and the both extremities for 5 years. He has been treated for leprosy with many kinds of drugs consisting of the herb medications for over 40 years. He also showed decreased cell-mediated immunity in skin tests. It is considered that depressed cellular immunity may be an important predisposing factor in the development of mutiple Bowen's disease in this case, .although arsenics can not be completetly excluded.

BACKGROUND: It is not yet clear whether the abnormal cytokine production in relation to serum IgE levels in atopic dermatitis (AD) is associated with the amount of mRNA of cytokine gene. OBJECTIVE: Our purpose was to delineate the effect of reciprocal correlation in the level of mRNA between interleukin-4 (I") and interferon-gamma (IFN-γ) in severe AD. METHODS: We examined 15 cases including 5 AD patients with high serum IgE (>2,000 kU/liter), 5 AD patients with low serum IgE (<100 kU/liter), and 5 healthy controls. Using semi quantitative reverse transcription-polymerase chain reaction, IL-4 and IFN-γ gene expressions in peripheral mononuclear cells (PBMC) were examined. RESULTS: 1) IL-4 gene expression in spontaneous PBMC was higher in AD patient groups than in control group, significantly higher only in AD patient group with high serum IgE level (p < 0.05). 2) IFN-γ gene expression in spontaneous PBMC showed increased tendency in AD patient groups than in control group without statistical significance. 3) IL-4 and IFN-γ gene expressions in stimulated PBMC were not different among all three groups. CONCLUSION: In light of our results, high and low IgE subgroups in AD can exist and AD may not be R characterized by the shift in the reciprocal relationship between IL-4 and IFN-γ when T cells are stimulated under antigen presenting cell-independent conditions.

STATEMENT OF PROBLEM: The current trend in prosthodontics is the adoption of a conservative approach to preparing dental prostheses by minimizing the amount of sound tooth structure removal during preparation. PURPOSE: The major disadvantage of the adhesion bridge is the inherently poor resistance to dislodgement that its use in areas subjected to high occlusal load is limited. The purpose of this study was to compare the dislodgement resistance of Bio-pin(R), conventional 3-unit and adhesion bridges. MATERIAL AND METHODS: The experimental groups were classified as follows: .Group I : 3-unit bridge cemented using Super-Bond. C&B .Group II : Adhesion bridge cemented using Super-Bond. C&B .Group III : Bio-pin(R) design adhesion bridge without incorporation of Bio-pin(R) (cemented using Super-Bond. C&B) .Group IV-1: Bio-pin(R) retained adhesion bridge incorporating a single Bio-pin(R) (cemented using Super-Bond. C&B) .Group IV-2: Bio-pin(R) retained adhesion bridge incorporating a single Bio-pin(R) (cemented using Panavia. F) .Group V : Bio-pin(R) retained adhesion bridge incorporating two Bio-pins. (cemented using Super-Bond. C&B) RESULTS: The results of this study were as follows: 1. Significant differences in dislodgement resistance of the restorations were found between Group I, Group II and Group III (p<0.05). No significant differences in dislodgement resistance of the restorations were observed between Group I, GroupIV-1 and GroupV. However, there were significant differences in dislodgement resistance between GroupII and the other groups (p<0.05). 2. No significant differences in dislodgement resistance of the restorations were observed between GroupIV-1 and GroupIV-2, both of which utilized a single Bio-pin(R). However, significant differences were observed when GroupIII was compared to either GroupIV-1 or GroupV (p<0.05). 3. No significant differences in dislodgement resistance relative to the type of dental cements used were found. CONCLUSION: From the above results, it is concluded that the dislodgement resistance of Biopin. bridge restorations utilizing a single Bio-pin(R) is similar to that of a conventional 3-unit bridge. The results also suggest that Bio-pin(R) bridge restorations using a single Bio-pin(R) are a viable alternative to the conventional 3-unit bridge when minimal removal of sound tooth structure and fulfillment of both function and esthetic aspects are considered.

Korean Journal of Dermatology 1995;33(1):76-84
BACKGROUND: Epidermal growth factor (EGF) , a potent stimulant of epithelialization, has been noted to increase the tickness of the epidermis, increase the epithelial cell proliferartion and keratinization, and accelerate wound contraction. OBJECTIVE: Our purpose was to evaluate the efficacy of topical application of recombinant human epidermal growth factor (rhEGF) in the healing of full-thickness excision and burn wound. METHODS: Full-thickness excision and burn wound were made on the back of the male Wistar rat. Recombinant human epidermal growth factor was applied twice a day and the size of the wound was measured with planimetry every other day for 21 days. The keratinocytes of the circumcised foreskin were cultured in different concentrations of recombinant human epidermal growth factor and proliferation of the keratinocytes was evaluated. RESULTS: 1. Regardless of wound types or base types, wound healing in the experimental groups (rhEGF 10, 30, 50g/g) was generally better than that in the control or vehicle group. 2. The duration of wound healing was decreased as follows in order; in full-thickness excision wound, rhEGF 50 g/g group, rhEGF 30 g/g group, rhEGF 10 g/g group, vehicle group, and control group and in full-thickness burn wound, rhEGF 30 g/g group, rhEGF 50g/g group, rhEGF 10g/g group, vehicle group, and control group. 3. In the biopsy specimen taken from the wound at 9th and 13th day, neodermis, neovascularization, the thickness and maturation of the collagen bundles, and reepithelithelialization were more increased in the experimental groups than in the control or vehicle group. 4. In vitro culture of epidermal cells showed similar proliferation in the concentration of rhEGF higher than 10 ng/ml. CONCLUSION: these findings suggest that topical application of recombinant human epidermal growth factor in the healing of full-thickness excision and urn wound.
