A 70 year-old male visited with 1 month history of dark brown, hard, non-movable subcutaneous nodule on the anterior chest. Histopathologic findings were compatible with the metastatic transitional cell carcinoma of the urinary bladder.

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.

BACKGROUND: Hydration, the water content of the stratum corneum, is an important factor in both the appearance and the barrier function of the skin. Many non-invasive methods have been developed in order to assesa the hydration state of the skin and the effect of various moisturizers. The hydrometer and carneometer are commercially available instruments which are widely used in dermatologic research. OBJECTIVE: Our purpose was to compare the measuring usefulnes of both instruments on normal subjects with a wide range of hydration states of the hornylayer. METHODS: We measured the conductance with the hydrometer and the capacitance with the corneometer in various hydrating eonditions and compared both insruments. RESULTS: Conductance had a non linear correlation with capacita ice. Capacitance measured with the corneometer had a high sensitivity to moisture in a wide range of hydration levels. On the other hand, conductance guaged with the hydrometer showed a few sensitivity to moisture at a low level. When the hydretion level was measured after a moiturizer was added, 10 % urea cream showed a sharp increase by 256% in terms of conductanae, and H-base by 97.8%. Mineral oil decreased by 41.5% and petrolatum by 62% respectively. On the other hand, when measured in terms of capacitance under the same conditions as above, 38.9 increase in 10% urea cream, 19.3% increase in H-base, 20% decrease in mineral oil, and 43.5 % decrease in petrolatum were reported. Conductance showed a higher hygroscopicity and a lower water holding capacity than capacitance did. When the measurement of the moisture level iri virious parts of the human body is performed, the corneometer provided us with more stable alies than the hydrometer. While the hydrometer can not the available and appropriate under the condition of insulation, the corneometer can measure moisture levels even down at the depth of 250mm. When measured after the oily surface of the forehead was cleansed with soft tissue, conductance and capacitance revealed higher values of moisture levels than before the eleanin. However, there is no statistical significance in these values. CONCLUSION: The hydrometer is a more appropriate tool for the measurement of moisture at a high level, and the corneometer at a low moisture level. The hydrcmeter is a more sensitive method of measuring the increase and the decrease in the moisture level.

Skin tags are very common skin tumors in middle age. In spite of their frequent occurrence, there was no reported cases of verruca vulgaris developing on the soft fibroma. We report a case of verruca vulgaris developing on the bag-like skin tag. We think that the incidence of HPV infection on the large skin tags may be higher than on normal skin due to their protrusion and repetitive irritation.

Neurocutaneous melanosis is a rare congenital syndrome characterized by the presence of large or multiple congenital pigmented nevi and a benign or maigrant pigment cell tumor of the leptomeninges. The s ndrome is thought to represent an erroi in the morphogenesis of the embryonal neuroectoderm. Even in the absence of melanorra, symptomatic neurocut.aneous melanosis has extremely poor prognosis. We report a case of neiirocutaneous melanosis in 38-year-old male. He was noted at birth to have a giant pigmented nevus on the bathing trunk area. He presneted with severe headache. Brain CT sca n was performed and 4 x 4cm sized well demarcated contrast enhanced mass was seeii in the right frontal lobe. Histopathologically, the tumor was composed of malignant melanoma cells. Multiple skin biopsies werperformed on the giant pigmented nevus and small nevi. All of the specimens revealed patterns typical of cornpound nevi. Dermatologists following patients with large or multiple congenial pigmented nevi should be aware of this condition to aid in prompt diagnosis.

17,966 new outpatients who visited the Department of Dermatology of Wonju Christian Hospital from 1985 to 1989 were analyzed statistically. The study results are summarized as follws : 1. Among the 17,966 outpatients, the total number of male patients were 8358 (46.5%) and female patients were 9608 (53.5%). 2. In age distribution, the most frequent age groups were lst decade (24.0), 2nd decade (16.5), and 3 rd decade (25.5) amounting to 66% of the total outpatients. 3. The 15 most common dermatoses were dermatophytosis, atopic dermatitis, urticaria, acne, seborrheic dermatitis, allergic contact dermatitis, other eczema, hypopigmentary disorder, bacterial infection, psoriasis, insect bites, and herpes zoster. 4. Those dermatoses which showed increasing tendency were other eczema, hypopigmentary disorder, herpes zoster, and those of decreasing tendency were scabies, bacterial infection. psoriasis, insect bites. 5. Seasonal distribution. showed those diseases occurring most frequently during the summer season were dermatophytosis, insect bites. urticaria, acne, eczema, contact dermatitis. hypopigmentary disorder, bacterial infection. and herpes zoster. The incidence of atopic deratitis. and psoriasis were incfreased during the winter season. 6. In sexual distribution sebourrheic dermatitis. and scabies were more frequent in the males. whereas with urticaria. acne, contact dermatitis, and other eczema the females were more commonly affected. 7. In age distribution, atopic dermatitis, bacterial infection, and insect bites were the most frequent in the Ist decade. Dermatophytosis. urticaria, acne, seborrheic dermatitis, contact dermatitis, other eczema, hypopigmentary disorder, drug eruption, and psoriasis were most frequent in the 3 rd decade, with scabies in the 2nd decade, and herpes zoster in the 6th decade. 8. The distributions of dermatoses as disease groups, were eczema (23.8%), dermatophytosis (13.9%), urticaria-drug eruption (12.2%), skin appendage disorder (11.2%), and viral infection (8.1%), which constituted 69.2% of the total.
