BACKGROUND: Beckers nevus is a benign lesion that may be congental or acquired, macular or papular, hairless or hypertrichotie. OBJECTIVE: Our pcrpose was to describe the clinical findings of Eeckers nevus and to establish a method for the histologic diagnosis of Beckers nevus. MEHTODS: We reviewed PF skin biopsies and their clinical finding from 28 patients with Beckers nevus during a 10 year period from January 1981 to January 1991. Results : The results were summarized as follows. A Clinical characteristics 1. Sex distribution showed of male predominence with male female a ratio of 1.5:1. Age of onset was predominent in less that 5 years old and puberty. 2. The lesions were located on the trunk(24 cases), head & neck(8 cases), extremities(6 cases), and were repsilateral in 26 cases, bilateral in 2 cases. 3. The lesions were accompanied by hair in 17 cases(61%). The shaies of the lesions were reticulated (75 %), patch(18%), mottled(7%). 4. Hairs were distributed as follows : abdomen(100%), scapula(100 %), extremities (83%), cheek(80 %), neck(67 %), chest(40%). All lesions of the face had follicular papules. 5. Associated skin diseases were : smooth muscle hamartoma(3 cases), striae distensa(2 cases), steroid acne(2 cases), pigmented nevus(2 cases), and verruca plana(1 case). B. Histopathologic characteristics 1. The lesions were accompanied with plugs in 21 cases, which were follicular, acrosyringeal, epidermal. 2. Elongation of the rete ridge and hyperpigmented basal cells were observed in the epidermis in all cases. 3. The shape of the rete ridge in Beckers nevus has its characteristic appearance, which is single, bridging and reticulated. Single, bridging and reticulated shapes cexisted in 17 cases(61%). 4. Inflammatiry cell infiltrations were present in all of the upper drmis, in which melanophages(21 %), hair follicles(89%) and smooth muscle hamartoma(3cases) w ere observed CONCLUSION: These findings indicated that the shape of the rete ridge in Beckers nevus has its characteristic appesrance and can be useful for the diagnosis of Beckers nevus.

We present the therapeutic effects of an aromatic retinoid (Ro 10-9359) in two cases of sex-linked ichthyosis. Case 1, Uncle of Case 2, was a 24-year-old male who had had dark brown scales on the trunk and upper extremities for 15 years. Case 2 was a 10-year-old boy who had had dirty brown scales on the trunk and lower extremities since 3 years of age. The diagnosis of sex-linked ichthyosis was made by characteristic scales and histopathologic findings. Initially, both patients received an oral aromatic retinoid (Ro 10-9359) with a daily dose of 1.5mg/kg body weight for the first two weeks. Thereafter the drug was tapered gradually to the dose of 0.5mg/kg body weight according to the therapeutic response. There was near complete clearing of the skin lesions in both patients after 10 weeks treatment. Side effects were of mild intensity and included dryness of mouth and nose, chelitis, paronychia and arthralgia of knee joint.

Dukes' stage of colorectal carcinoma has proven to be the most reliable and conventional prognostic indicator, followed by histological grade, lymph node metastases, tumor size, vascular and neural invasion. Flow cytometric analysis of DNA ploidy and S-phase fraciion (SPF) was examined to elucidate the correlations between sex, age, preoperative serum carcinoembryonic antigen (CEA) value, Dukes' stage, tumor site, size, gross features, histologic grade, and survival rate in 117 paraffin-embedded tissues of 68 cases of colorectal adenocarcinoma in Dukes' stage and 39 cases of colorectal adenoma and 10 cases of normal colonic mucosa. DNA aneuploidy was detected in 30 cases(44%) in adenocarcinomas and 6 cases (15%) in adenomas. Although the DNA ploidy and SPF did not show any correlation with sex, age, preoperative serum CEA level, Dukes' stage, tumor size, site and gross features, the incidence of DNA aneuploidy in the moderately differentiated adenocarcinomas was significantly higher than that of the well differentiated adenocarcinomas (p=0.0127) An apparent correlation was found between survival rate and DNA ploidy, Dukes' stage, histologic grade and preoperative serum CEA value. Dukes' stage was the most reliable prognostic indicator (p=0.0106), followed by histologic grade (p=0.0230), DNA aneuploidy (p=0.0251) and preoperative serum CEA level. (p=0.0369) In the patients with Dukes' stage C, DNA aneuploidy was more important than histologic grade as a prognostic indicator (p=0.0202). Although high SPF, greater than 21% in adenocarcinoma, was associated with the lower 5-year survival rate (12.0%), it was not statistically significant. These results suggest that DNA aneuploidy is regarded as biologic aggressiveness and considered as independent and/or dependent prognostic indicator along with Dukes' stage. However, prognostic utility of the SPF was not significant.

Epidermolysis bullosa simplex (EBS) is a group of autosomal dominantly inherited genetic disorders characterized by blistering due to mechanical- stress-induced degeneration of basal epiderrnal cells. Recently, it was discovered that EBS is induced by keratin 5 and 14 gene mutations. Weber Cockayne (W-C) EBS is the mildest type, with blistering concentrates primarily on palar and plantar regions, and basal cell cytolysis by keratin filament perturbations is present. Herein we report a case of W-C EBS with its ultrastructural findings. Electron microscopy showed cytolysis and separation of the basal epidermal cells, mainly at the subnuclear cytoplasm. The cyto- plasm of basal cells showed edema, loosening and intact rnitochondria. Besides the cytoplasmic changes, the nucleus also showed lytic degeneration. Characteristically, dense condensation of tonofilarnent was observed, which suggests that W-C EBS is. also a disorder of keratin.

We have observed the dark effect of 8-methoxypsoralen(8-M(P) on the viability and DNA synthesis in human lymphocyte cultures after stimulaticn with phytohemagglutinin (PHA) in the absence of ultraviolet A radiation. The concentratioiis of 8-MOP was 0.5-32 ug/ml. We have also measured the LDH activity in supernatant. of lymphocyte cultures treated with 8-MOP. The results were as follows: 1. There was no 8-MOP dose-dependent decrease in the viability of lymphocytes up to 8- MOP 32pg/ml. 2. There was a 8-MOP dose-dependent decrease in PHA-induced DNA synthesis of lymphocytes from the concentration of 8-MOP 2 ug/ml. 3. There was a time-dependent decrease in PHA-induced DNA synthesis of lymphocytes at the concentration of 8-MOP 32 ug/ml. 4. There was no LDH release in supernatant of lymphocyte ciltu es after incubation with 8-MOP up to 8-MOP 32ug/ml.

Familial benign chronic pemphigus is characterized by a recurrent eruption of plaques of closely grouped vesicles that most frequently occurs about the neck, axilla and groin, singly or in combination with similar lesions in the intertriginous area. A 27-year-old male has had recurrent vesicles, fissures, maceration and crust formation in inguinal and perianal area for 3 yeare. The lesion manifested circinated form of vesicles, fissured and scaly patches over the inguinal, scrotal and perianal area. There were actively inflammatory border, resembling tinea cruris in the inguinal area. Authors diagnosed with clinical symptoms, laboratory examinations, and light and electron microscopic examination.

Epidermolysis Bullosa Simplex is characterized by autosomal dominant rnheritance, and chronic noninflammatory conditions in which the clinical lesions, erosion, blisters usually result from relatively minor mechanical trauma to the skin, especially joints of hands, elbows, knees, and feet and other sites subject to repeated trauma The lesiona are present or appeared after a few days after birth or shortly after especialy of the lower legs or feet, and not involved at naiIs or mucous membranes. Though infection is not common on the feet or hands, even infected lesions generally heal with out scarring. 2 cases of Epidermolysis bullosa simplex were experienced, the one was 5 month old male baby who had fresh vesiculobullous, hemorrhagic bulla, crusts, exfoliation, no nail dystrophy, since a few days after birth. The another was 5 month old female baby, who had pea sized tense bulla, and exfoliations on the hands and feet. Diagnosis confirmed by clinical features and histological findings. Literature were reviewed in comparison with mechanobulIous disease.

The object of this study is to evaluate the effects of repeat,ed PUVA applications on epidermal melanocytes. The changes in the number of melanocyes is compared to the frequency of PUVA applications. 26 adult male C57BL mice were used. About an hour after appliction of 0.1% solution of 8-methoxypsoralen, UVA was delivered two or four times a weels on both ears of mice with blacklight fluorescent tube l,'Waldmann UV-800). Weekly examinations of melanocytes were made for 4 weeks on split epidermal sheets treated with DOPA solution. The results were as follows. 1. Repeated PUVA applications revealed a significant increase in the number of melanocytes. With PUVA, two times a week, the number of me anocytes was increased from 83.2+/-7.2/mm2 (unir radiated ear) to 250.6+/-34.7/mm2 after ore week and 525.5+/-66.7/mm2 after 4 weeks. With PUVA, four times a week, the number of melanocytes was increased from 83.2+/-7.. 2/mm2 (unirradiated ear) to 437.0+/-74.0/mm2 after one week and 686.3+/-27.8/mm2 after 4 weeks. 2. PUVA, four times a wcek, elicited higher melanocyte density than PUVA, two times a week, under the same period of treatment. 3. After two weeks, the same amount of irradiation increased the number of melanocytes more in PUVA, four times a week than in PUVA, t,wo times a week.
