Annals of Dermatology 1999;11(2):78-81
Solitary morphea profunda is a rare form of scleroderma, characterized clinically by a solitary sclerotic plaque, and histologically by marked dermal and subcutaneous fibrosis with an inflammatory infiltrate. We describe another case of this entity presented with an ulcerative, indurated plaque on the left iliac crest, which histologically revealed a focal incidental acantholysis in the overlying epidermis and a marked eosinophilic infiltration through the dermis to the sub-cutaneous tissue.

Annals of Dermatology 1994;6(1):1-8
BACKGROUND: Monofunctional psoralens plus UVA radiation are not severely phototoxic and have less mutagenic activity than bifunctional psoralens plus UVA radiation. OBJECTIVE: The purpose of this study was to evaluate pigment producing effect using various concentrations(0.02%, 0.1%, 0.5%) of monofunctional psoralens such as angelicin, khellin and comparing it's effect with TMP in topical photochemotherapy. METHOD: Ninty three C57BL mice were painted with either angelicin, khellin or TMP solution in concentrations of 0.02%, 0.1% and 0.5% each and were UVA irradiated. Skin biopsies were performed at 1,3,5 weeks after UVA irradiation. The pigment producing effects were measured by the number, area and perimeter of the melanocytes after topical PUVA. RESULTS: The comparison of melanocyte numbers between different psoralens after five weeks of photochemotherapy showed a significant difference in decreasing order of TMP, khellin and angelicin. The area and perimeter of melanocytes were larger in the TMP group after five weeks photochemotherapy than the other group. However in the khellin and angelicin group, the area and perimeter of melanocytes were not increased by increasing the frequency of the UVA irradiation. CONCLUSION: The number, area and perimeter of melanocytes after topical PUVA increased in the TMP group compared to angelicin or khellin group. We expect the clinical application of angelicin and khellin in vitiligo is possible considering the result of the study of pigment producing effect with a higher concentration and higher dose of UVA.

BACKGROUND: The photsensitizing effect of quinolones has been recognized since their introdulation as an antibacterial agents. Recently several new second eneration antibacterial agents of this pharmacological class have become available for therapy, and are gaining increasing impotance. OBJECTIVE: To reveal the phototoxic potentials of some new quinolones by photohemolysis test, estimation of fluorescenc spectra, and Candida albicans test. METHODS: Nalidixic acid and four second-generation quinolones(ciprofloxacin, enoxacini, norfloxacin, and ofloxacitid were examined by fluorescence spertra which measured t.he phototoxc potentials by photochemial instability, photohemolsis test for the phototoxic properties against cell membranes and Candida tlbicans test for phototoxic properties against DNA. RESULTS: All drugs showed a fluorescence spectra within 360 nm to 450 nm, and in the photohemolysis test, all studied drug except ofloxacin got above 5% hemolytic value, and all drugs showed clear zone. in Candida albicans test after 48hours. CONCLUSION: These results suggested that all tested drugs were photochemically unstable. According to the mechanisris of cellular phototoxicity, ciprofloxacin, enoxacin, and norfloxacin was phtototoxic to nucleus and cell membrane, whereas ofloxacin was phototoxic to nucleus only.

We report herein three cases of subcutaneous sarcoidosis without apparent internal lesion. The patients had multiple subcutaneous nodules on the extremities and abdomen. Hyper-gammaglobulinemia, a relative increase of T suppressor cells, and increased serum angiotensin converting enzyme level and skin anergy were observed. Histopathologic findings revealed sarcoidal granulomas involving the subcutaneous fat tissue. The lesions of two cases resolved spontaneously and the other one case required systemic corticosteroid therapy.

We described a case of diffuse biphasic cutaneous amyloidosis, a unique form of localized cutaneous amyloidosis. A 41-year-old man has gradually developed a lichenoid papular and a grouped spotted pigmented macular eruption on the trunk and upper extremities over the past 15 years. Histopathologic examination revealed that amyloid deposits were present in the papillary dermis. It was confirmed by Congo red staining, immunohistochemistry and electron microscopy. There was no evidence of systemic amyloidosis.

We investigated the clinical aspect and immunologic parameters of childhood and adult vitiligo in our clinics and made a comparative study. The childhood vitiligo showed the following results : similar incidence of clinical patterns with adults except for the lower incidence of the acrofacial type than in adults ; less involvement in the extent of lesion of disease than in adults ; higher incidence of family history than with adults ; of the precipitating factors, trauma is the main one whereas emotional stress is for adults ; higher association with halo nevi than adults ; and lower incidence of serum autoantibodies than adults. We have ascertained that childhood vitiligo is a distinct subset of vitiligo, showing the above features which will be studied in more patients in a long term follow-up clinical study.

The ulcerative colitis is a relatively common disease in the European and North American countries aince Dr. Wilks has first reported the cases in 1895, But in Korea, this disease is a rare entity and only a few case have been reported. However, rescently the diagnoetic methods for ulcerative colitis are much developed we have experienced 28 cases of ulcerative colitis which were diagnosed by endoscopy, barium enema exam and biopsy. Therefore a total of 28 patient with ulcerative colitis diagnosed and treated at the department of internal medicine of HYUH from June 1979 to June 1986 was reviewed. We obtained the results as follows; 1) The sex distribution assumed a ratio of 1 to 1.33 with 12 males and 16 females. 2) The age dietribution was relatively even but the majority of cases were between 5th and 6th decade (32.1%), 3) The most prominent clinical symptoms were rectal bleeding, abdominal pain, diarrhea, fever, wight loss and vomiting. 4) Significant laboratory findins were anemia, eleveited ESR, leukocytosis, positive stool OB, electrolyte imbalance and decreased serum albumin level. 5) As to the extent of disease determined by the barium enema examination and endoscopic exam., rectum or rectosigmoid colon is involved in majority of the cases (92.8%). 6) The endoscopic examination was performed in all 28 cases and showed significant findings such as ulceration, hyperemia, mucosal friability, bleeding etcs. 7) The barium enema examination was performed in 19 cases and showed positive findings such as ulceration, luminal narrowing, bowel shortening and rigidity in 17 cases. 8) 21 of 28 patients treated by medical therapy showed relatively improved but 4 of 28 patients was exacerbated or relapsed and one has expired.

Endoscopic injection sclerotherapy(EIS) has been widely used in treating and eradicating acutely bleeding esophageal varies, but may be associated with some undesirable local and systemic complications. Endoscopic variceal ligation(EVL), which consists of mechanicai ligation and thrombosis of varices using elastic o-band, has been recently developed as a non operative alternative to EIS. We performed EVL in 65 patients who had bled from esophageal varices between November 1991 and September 1993. Total 274 sessions were performed and 774 o-bands were used. Six patients were actively bleeding and all of them were successfully controlled by emergency EVL. During the follow-up period, five patients who had combined hepatoma died. Varices were eradicated or reduced grade I in 43(71.6%) of the 60 survivals by 8-36 ligations(mean 15.6 ligation) in 2-13 EVL sessions(mean 5.6 sessions). During follow up period, five patients had recurred from grade 0 to grade 2 or 3 in 106-260 days(mean 182.6 days), and then eradicated by repeated EVL. During or after EVL, there were no complications, except mild substernal distress and mild dysphagia in 17 and 7 patients respectively. These results showed that EVL is a safe and effective method for eradication of bleeding esophageal varices.

Korean Journal of Dermatology 1994;32(1):75-82
BACKGROUND: The p53 gene mutations have been found in a variety of human skin cancers. To date most studies concerning p53 gene mutations in skin cancers focused on squamous cell carcinoma(SCC) and its precancerous lesions such as actinic keratosis and Bowen's disease, especially related to ultraviolet light, but few on basal cell carcinoma(BCC). OBJECTIVE: This study was aimed to investigate the aberrant expression rates on p53 mutant gene in BCCs as well as in SCCs and their changes depending upon their clinicopathologic characteristics. METHODS: An immunohistochemical study was employed using the mouse monoclonal antibody raised against recombinant human p53 in 30 BCCs and 16 SCCs. Also, clinical and histopathologic analyses for age, sex, site, duration and histopathologic classification were performed. RESULTS: p53 immunoreactivity was observed in 57% of BCCs and 75% of SCCs. In BCCs P53 immnoreacticvity was increased by up to 61% in cases(28/30) developed on the sun-exposed area. In SCCs p53 immunoreactivity(89%) on non-sun-exposed area was unexpectantly higher than that(57%) on sun-exposed area. No significant correlation between p53 imunoreactivity and clinicopathologic characteristics in BCCs and SCCs was noted. CONCLUSION: Mutations of p53 may play an important role of the pathogenetic sequence in a large part of the pathogenetic sequence in a large part of BCCs as well as SCCs.
