A 4-year-old boy has had a solitary sclerotic depressed plaque on the right anterior chest since birth. The histopathologic findings are consistent with morphea profunda: thickening, hyalinization, and homogenization of collagen bundles in the dermis and subcutaneous tissues, admixture with a prominent lymphocytic and plasma cell infiltrate, and sweat glands en-trapped between the thickened collagen bundles. We report a case of congenital solitary morphea profunda.

Plexiform neurofibroma is considered a pathognomic of Von Recklinghousen's disease, which involves the deep and large nerve trunk. These are large irregular nerve fascicles which result from an increase in endoneural matrix within individual nerve facicles, without an increased number of nerve fibers. We experenced a case of Von Recklinghausen's disease in a 24 year-old male who had variable cutaneous skeletal, and CNS lesions. He presented multiple neurofibromas, cafe-au-lait spots, and axillary freckles as common cutaneous lesions of NF-I and giant pigmentation, sacral hypertrichosis, and plexiform neurofibroma as unusual cutaneous lesions. Also he had a scoliosis, bowing deformity of the humerous and wedging deformity of the body of the 5th cervical spine as a skeletal manifestation and cortical calcification in the occipital area as a CNS manifestation.

BACKGROUND: Bentonite clay, which is a major component of mud pack, has been used for various purposes in cosmetics. Glycolic acid is known to be effective in the treatment of acne. Al-though those products are used widely, information on the mode of action and effects on the skin are little and controversial till now. OBJECTIVE: To investigate whether bentonite alone, or bentonite with glycolic acid in mixed formulation affect the stratum corneum leading to alteration on cutaneous barrier function and whether those products alter the lipid lamellae and desmosomes of corneocytes. MATERIALS AND METHODS: Mud pack-type ointment of bentonite, bentonite and 5% glycolic acid formulation, bentonite and 10% glycolic acid formulation were applied on the volar fore-arm of the five healthy men and flank skin of five 6-8 week old hairless mice. Transepidermal water loss and capacitance were measured. Electron microscopic examination after ruthenium tetroxide postfixation was performed on the flank skin of the mice. RESULTS: Transepidermal water loss(TEWL) increased immediately and normalized 4 to 6 hours later after removal of vapor permeable membrane in both mouse and human. Capacitance did not show any evidence of change in the water content of the stratum corneum. Electron microscopic examination revealed that lipid lamellae and desmosome of corneocytes were not de-graded, but lamellar body secretion and partially electron-lucent material was-increased in 10% glycolic acid and bentonite mixture-treated area. CONCLUSION: Barrier function of stratum corneum is not disturbed by bentonite and glycolic acid formulations at the concentration used. Barrier structures are not disrupted, but lamellar body secretion and partially electron-lucent material was increased by bentonite and glycolic acid formulations at higher concentration.

PURPOSE: Recently developed BMS(TM) (Zassi Bowel Management System(TM): Hollister Inc., Illinois, USA) can provide effective nonsurgical fecal diversion without the risks associated with colostomy creation and subsequent closure. Our aim is to evaluate the effectiveness of the BMS in diverting feces from the perianal wide surgical wound in patients with Fournier's gangrene. METHODS: BMS(TM) was applied in five patients (male: 2, median age; 44) with Fournier's gangrene from January 2000 to September 2001. The treatments consist of three times a day wound dressing after wide surgical debridement and intravenous antibiotic therapy. For evacuation of feces, twice daily warm saline irrigation was administered via BMS(TM) or low daily doses of polyethylene glycol solutions were orally taken in. An endoscopic and anorectal manometric study was done to evaluate possible mucosal complications and anorectal functional changes. RESULTS: The average duration of the BMS application was 41 (range, 22~63) days. The result of a manometric study after immediate removal of the BMS(TM) showed a decreased mean resting pressure (range: 22~36 mmHg) and a decreased mean squeezing pressure (range: 32~39 mmHg). After 3 days, the sphincter pressure had improved markedly: mean resting pressures of 38, 45, 60, and 63 mmHg and mean squeezing pressure of 78, 89, 91, and 101 mmHg respectively. Fecal incontience was not noted in any patient. Other possible mucosal complications were not noted. There were no mortalit. CONCLUSIONS: BMS(TM) application in Fournier's gangrene patients after surgery successfully avoids a defunctioning colostomy. Furthermore, no significant complications were noted over a prolonged period up to 63 days.

We have experienced a 14 year old female patient who had suffered from headache, dizziness, exertional dyspnea and chest pain during 6 months. She was diagnosed as primary pulmonary hypertension by ultrasonogram and cardiac cathererization. On the cardiac catheterization, there was elevated pulmonary artery pressure and normal pulmonary wedge pressure. We report this case with related literature review.

The antiphospholipid antibody syndrome is an acquired multisystemic disorder characterized by persistent elevated antiphospholipid antibodies and/or hypercoagulation in veins or arteries, or both. The clinical manifestations of the antiphospholipid antibody syodrome are recurrent thrombosis, fetal loss, thrcenbocytopenia, and various cutaneous lesions. Skin lesions are the first sign of this syndrome in 41% of patients and systemic thrombosis develops in 40% of them. Livedo reticularis is the most common cutaneous finding of the antiphosphotipid antibody syndrome. Although vasculitis has not been frequently noted in antiphospholipid antibody syndrome, some vasculitis such as polyarteritis nodosa, giant cell arteritis, and other nonspecific vasculitides have been found in association with antiphospholipid antibody syndrome. We present a male patient with typical manifestations of leukocytoclastic vasculitis with deep vein thrombosis and positive antiphospholipid antibodies. It suggests that a case of antiphospholipid antibody syndorme was accompanied with cutaneous leukocytoclastic vasculitis.

Tegafur [1-(tetrahydro-2-furyl)-5-fluorouracil], the prodrug of 5-fluorouracil, is an anticancer agent. Several cutaneous reactions have been reported following systemic 5-fluorouracil for the treatment of malignancies. We report a patient with marked inflammation of the actinic keratosis following the use of tegafur for stomach carcinoma. The side-effect with 5-fluorouracil was beneficial as most actinic keratosis cleared following the inflammatory reaction. Dermatologists and oncologists should be aware of this potential side-effect, not only because it may become more prevalent but, most importantly, because it is not an allergic reaction to 5-fluorouracil but a dose-dependent response, and the chemotherapy may be continued in most patients.

Deep skin and soft tissue defects with exposed bone and tendon is difficult to treat, because skin graft rarely survives and flap surgery is sacrifice of donor site. Since "Stage I" membrane was developed by Yannas and Bruke in 1980, numerous kinds of artificial skin have been developed. The adaptability of "Terudermis", developed by the Terumo Co., as an artificial skin composed of sponge made of a fibrillar atelocollagen and a heat-denatured atelocollagen, was clinically evaluated on application to 13 cases presenting deep skin and soft tissue defect with exposed bones and tendons from October 1997 to march 1998. Terudermis has the advantage of allowing early incorporation of fibroblasts and capillaries into its collagen sponge due to very weak dehydrothermal cross-linking. Before Terudermis graft, several days of wet dressing and debridement were required to prepare healthy well-vascularized bed because Terudermis was weak on unsanitary wounds. After bed preparation, Terudermis was grafted like usual skin graft. Tie-over bolster dressing or compressive dressing was used case by case. The dressing was opened 2~3 days after Terudermis grafting. Wet dressing was done daily until the skin graft was done. Autologous skin graft was done 2-3 weeks after Terudermis graft. Our clinical results indicated that Terudermis was beneficial in treating 77% of our patients. Through the use of this new method, treatment of severe skin and soft tissue defects that are usually treated by musculocutaneous or other conventional skin flaps can be replaced by Terudermis as an new artificial dermis.

10.The Changes of Cytokeratin 19 and bcl-2 Expression during Hair Follicle Morphogenesis in Human Fetal Skin.
Korean Journal of Dermatology 1997;35(4):712-719
BACKGROUND: During human skin development, hair follicles dynamically develop to adult hair structures through the hair germ, hair peg and bulbous hair peg. In this perspective, it is thought that the distributions of stem cells changes following the stage of the hair follicle morphogenesis. OBJECTIVE: The purpose of this study was to observe the distribution of stem cells following the stage of hair follicle morphogenesis. METHODS: Skin was obtained from the abdomen skin of 15 human fetuses, ranging from 10 to 23 weeks of gestational age. Immunoperoxidase staining was performed on frozen sections using monoclonal antibodies to cytokeratin 19, known as a stem cell marker, and bcl-2, a factor to prevent cells from entering the apoptotic pathway. RESULTS: 1. Cytokeratin 19 was expressed in the periderm, basal cell layer and condenced cells constituting the hair germ and peg. In the early bulbous hair peg stage, it was expressed in the entire outer root sheath cells, the bulge area and basal cells of the hair bulb. In the late bulbous hair peg stage, it was expressed in the bulge area, outer root sheath cells only of inferior portion and some of the germinative cells of the hair bulb. 2. Bcl-2 was expressed in the basal cells intermittently, condenced cells constituting the hair germ and aggregates of dermal mesenchymal cells concentrating along the hair germ. In the hair peg stage, it was expressed in the entire basal cell layer, condenced cells constituting the hair peg and aggregates of dermal mesenchymal cells along the hair peg. In t.he bulbous hair peg stage it was expressed in the basal cells of the infundibulum, sebaceous gland, bulge area, germinative cells of the hair bulb and the dermal papilla cells. CONCLUSION: From the results obtained, we thought that the distribution of stem cells is dynamically changing following the stages of the hair follicle morphogenesis. It was also speculated that bcl-2 might have an important role in dermoepidermal interactions during hair follicle morphogenesis.
