Eccrine epithelioma is an exceedingly rare cutaneous tumor ancit is believed to represent the maligant counterpart of the eccrine dermal syringoma. It occirs as an infiltrating basaloid growth, usually on the scalp or head, that frequently recur, apparrntly because of inadequate excision. We report a case of this tumor in a 60-year-old female, who showed a well demarcated, tender nodule on her left parietal scalp which had been present for three years. Histopat.hologically, the tumor was composed of strands of darkly staining epithelial cell embedded in a dense fihrcus stroma with ductal differentiation and cyst formation.

Cavernous hemangioma is the most common primary tumor occurred in adults' orbit. This tumor has symptoms characteristically developing over several years with slowly progressive proptosis, eyeball deviation, hyperopia, diplopia and optic nerve compression. It's removal, necessary when there is progressive exophthalmos and visual deficit, is best performed en bloc to avoid intraoperative vleeding, the risk of residue, and potential further growth. In principle, surgical approach to the orbit must provide maximum safety and optimal visualization. The noncompressibility of the globe imposes greater demand on the need for some removal of the osseous orbit for surgical approach. This also must permit immediate functional and aesthetic reconstruction. The authors have experienced a case of large cavernous hemangioma in the orbit inferomedially. The surgical treatment of tumor was achieved by inferomedial approach combined with inferolateral orbitotomy. This surgical approach allows better visualization of the tumor and greater protection of essential anatomic structures. This also permits immediate functional and aesthetic reconstruction. So we present our case with a brief review of the literature related to orbital cavernous hemangioma.

There have been several reports of more than one type of porokeratosis occurring in the same family or the same individual. We hope to support the view of different phenotypic expressions of a common genetic aberration by describing an additional case of porokeratosis of Mibelli on the perianal area and DSAP on the face, forearms occurring in a 45-year-old man.

Many plastic surgeons have been tried to attain ultimate goal lies in restoring the original shape and function of the facial aesthetics, in reconstruction of deformities resulting from facial hypertrophic scar and skin defects. This would require consideration in terms of hanmony in color match, skin texture and thickness. Various forms of skin graft, local flap, distant flaps, free flap and tissue expander have been employed in restoring skin defects and deformities of the cheek and submental area, and the use of large local flaps utilizing the cervicofacial skin flaps or tissue expander have brought about improved aesthetic results. the authers have obtained satisfactory results in treating 2 cases of wide hypertrophic scar of the cheek and submental area with combination of wide cervical flap and intraoperative tissue expansion using foley catheter. the merits of this combined operative methods are as follows : 1. It is not necessory to keep tissue expander for a long period. 2. This technique is able to diminish the cost of multistage operation and using of tissue expander. 3. There is no psychologic problems due to undesirable facial appearance during tissue expansion period. 4. Rapid intraoperative tissue expansion by foley catheter during elevating wide cervical flap can allow to dissect one, preserving the perforators without bleeding in a short time. 5. Wide cervical flap and additional expanded tissue by means of intraoperative tissue expansion could brought into suturing avoiding tension of oral commissure and lip eversion. 6. Preservation of perforators of cervical flap above the platysma muscle raised flap's survival rate and then this result could prevent distal ischemic necrosis after flap coverage.

PURPOSE: This study compared the accuracy of an abutment-framework (A-F) taken with open tray impression technique combining cementon crown abutments, a metal framework and resin cement to closed tray and resin-splinted open tray impression techniques for the 3-implant definitive casts. The effect of angulation on the accuracy of these 3 techniques was also evaluated. MATERIAL AND METHODS: Three definitive casts, each with 3 linearly positioned implant analogs at relative angulations 0, 30, and 40 degrees, were fabricated with passively fitted corresponding reference frameworks. Ten impressions were made and poured, using each of the 3 techniques on each of the 3 definitive casts. To record the vertical gap between reference frameworks and analogs in duplicate casts, a light microscope with image processing was used. Data were analyzed by two-way analysis of variance and the Tukey test. RESULTS: The open tray techniques showed significantly smaller vertical gaps compare to closed tray technique (P < .05). The closed tray and the resin-splinted open tray technique showed significantly different vertical gaps according to the angulation of implant (P < .05), but the A-F impression technique did not (P > .05). CONCLUSION: The accuracy of the A-F impression technique was superior to that of conventional techniques, and was not affected by the angulation of the implants.

7.Expression of Elafin in the Epidermis of Cutaneous Fungal Infection.
Chong Hyeok KIM ; Hae Jun SONG
Korean Journal of Infectious Diseases 2000;32(1):21-26
BACKGROUND: Elafin is a serine proteinase inhibitor first discovered in keratinocytes from hyperproliferative human epidermis. In addition to the proteinase inhibiting domain, elafin contains multiple transglutaminase substrate domains which enable cross-linking to extracellular and cell envelope proteins. Several characteristics of elafin suggest potential anti-microbial activity. Elafin is absent in normal skin at protein level, but is induced in inflammatory and infectious dermatoses which threat the epidermal integrity by vesicopustule formation and neutrophilic cell infiltration. Cutaneous fungal infection is one of the well-known examples of diseases characterized by such condition. The purpose of this study was to check out the possibility that elafin may be involved in the pathomechanism of fungal infection. METHODS: The biopsy samples taken from 10 cases of superficial fungal infections, 10 cases of deep and systemic mycoses, 2 cases of slide culture specimens of Candida species, were used for the immunohistochemical tissue staining for elafin expression. Polyclonal anti-elafin was used in 1:300 dilution. As control, biopsy smaples of normal skin, ichthyosis, psoriasis were used for the staining for elafin expression. RESULTS: In the normal and ichthyotic epidermis, elafin expression was virtually negative. In superficial mycoses except candidiasis, elafin was expressed in the spinous layer of infected epidermis, and fungal structures in the stratum corneum were stained with elafin antisera. In the cases of dermatophytosis of ichthyosis patients, while fungal hyphae were stained with elafin antisera, epidermal cell did not express elafin. In candidial esophagitis, elafin was expressed in the esophgeal mucosa, but spores were not stained with elafin anti-sera. In slide culture of Candida species, spores were not stained with elafin antisera, also. In cases of systemic and deep mycoses, fungal hyphae and spores were stained with elafin antisera and epidermis adjacent to severe dermal inflammatory reaction showed elafin expression. CONCLUSION: Elafin may have certain role in systemic and cutaneous fungal infection to contribute to high resistance of the epidermis against proteolysis and fungal infections, and it is shown that elafin or elafin-like protein may also be produced and utilized by fungi themselves.

Korean Journal of Dermatology 1994;32(5):778-786
BACKGROUND: The changes in lipid composition during epidermal differentiation has been reported in human and animal models. Because of the difficulties in getting adeguate specimens from human subjects, the authors used easily obtainable circumcised prepuce for lipid analysis. OBJECTIVE: To investigate the changes in lipid composition duriig cornification of the epidermis, the lipid compositions of whole epidermis and stratum corneum were analyzed by thin layer chromatography(TLC). METHODS: From circumcied prepuce whole epidermis and stratum orneum were separated by 10mM EDTA(ethylene diamine tatraacetate) in PBS(phosphate-buffered saline) or heat(60C), and 0.5% trypsin in PBS respectively. Lipids were extracted with methanolctloroform-HO mixture(4:2:1.6, v/ v, Bligh-Dyer solvent), TLC was performed and lipid composition was quantitated by photodensitometer. RESULTS: In the composition of stratum corneum lipids, sphingoliids were the highest(33.3+2.9%) followed by cholesterol, free fatty acids and cholesterol esters in cleceasing order, there were small percentages of triglycerides, cholesterol sulfate and squalene. CONCLUSION: In this study the lipid composition of epidermis was similar to that of stratum corneum rather than those of previous reports on epidermal lipids, which may indicate the regional characteristics of epidermal/stratum orneum lipids in hyperkeratotic prepuie.

We report a case of infantile acute hemorrhagic edema in a 15-month-old boy. The patient showed multiple, bean to walnut-sized, red to purple-colored, indurated purpura with a cockade pattern on the face, earlobes, and extremities. Edema of the hands, feet, and earlobes was also observed. Laboratory examinations showed thrombocytosis, decreased serum CH50, and ketone in the urine. A skin biopsy taken from indurated purpura on the lower leg exhibited findings of acute leukocytoclastic vasculitis. Direct immunofluorescence examination showed deposition of IgM along the dermo-epidermal junction and C3 in the dermal vessel walls. With-out specific management except for fluid therapy to correct dehydration, the skin lesions cleared completely in 2 weeks, and recurrence has not observed.
