N/A Background: Xanthelasma palpebrarum does not regress spontaneously, its appearance is often seen as cosmetically disturbing. Treatment of xanthelasma may prove difficult due to its delicate location at the periorbit and sometimes its extensive dimension. Treatments include excision, electrodesiccation, chemical cautery and laser surgery. Objective: This study was designed to evaluate the effect of a CO₂laser for the treatment of xanthelasma palpebrarum. Methods: Twenty patients with a total of 56 xanthelasma lesions, were treated with a CO₂laser. The Follow-up period of observation was between 12 and 84 months. Results: All lesions could be removed completely with a single laser treatment. Only transient pigmental change (hypopigmentation 1/20, hyperpigmentation 1/20) was observed without scarring. 8 patients developed a recurrence of xanthelasma. Conclusion: The CO₂laser represents an effective means for treating xanthelasma, but recurrence is common. (Korean J Dermatol 2004;42(3):250~255)

Untill now occasional cases of Jellyfish stings have been reported in Korean literatures but all of the reported patients contracted the stings abroad out of the country. Recently we have found a case of the jellyfish stings first in Korean coastline. The patient was an 11-year-old girl, who got the sting while she was swimming in the southern west coast of the country. The initial skin lesions showed typically whipped appearance and subsided in a month after taking both courses of the immediate toxic reaction and the late allergic reaction. Considering the ecological changes of the sea waters of the Korea, we think the jellyfish stings would occur more frequently also in the country and dermatologists should be familiar with the dermatitis.

Merkel cell carcinoma is an uncommon malignancy of the skin that was first described by Toder in 1972 and occasionally found concurrent with other malignancies such as squamous cell carcinoma, basal cell carcinoma or, as in the present study, with Bowen`s disease. We report a unique case of Merkel cell carcinoma coexisting with Bowen`s disease on the left forearm of a 42-year-old man who had a past history of multiple Bowen`s disease. The tumor was excised and the specimen was examined histopathologically. The tumor cells exhibit trabecular, cord-like arrangement in the dermis, partly extending into subcutaneous tissue without involvement overlying epidermis, where Bowen`s disease lesion was absent but the peripheral patch area exhibit Bowen`s disease. The tumor cells in the dermis were positive for neuron-specific enolase and chromogranin. This is the first report of a case of Merkel cell carcinoma associated with Bowen`s disease in Korea.

Purpose : To evaluate the utility of mammography and ultrasonography in study of morphologic differential diagnosis between malignant and benign mass. Materials and Methods : Average age of patients with breast cancer was 48.4 year-old, and that of fibroadenoma was 29.4 year-old. The equipments used for examination were MF-159 high frequency mammography(Bennet Co.) and Acoustic image 5200S. We evaluated mammographic findings about breast parenchymal pattern, calcification, margin and size of the mass associated tumor nature, and ultrasonographic findings about shape, height and width, internal homogenicity and echo pattern, wall contour, boundary echo, and posterior shadow in breast mass. Thirty-seven of mammographic findings and 34 cases of ultrasonogreaphic findings in pathologically proven breast cancer and 34 case of mammographic findings and 71 cases of ultrasonographic findings in breast fibroadenoma were reviewed retrospectively. Results : In mammographic study, the parenchymal patterns of breast cancer according to Wolfe classification were NI(16.2%), PI(24.3%), P@(37.8%), and DY(21.6%) and those in fibroadenoma were NI(3.1%), Pl(11.7%), P2(35.2%),and DY(50%). Mammographic findings about presence of calcification were as follows; only calcification(16.2%), only mass(51.3%), and mass with calcification(32.5%) in breast cancer, and only mass(91.2%), mass with calcification(8.8%) in fibroadenoma. The features of mass margins were classified as ill-defined margin(45.9%), well-defined(5.4%), and well-defined with partial spiculation(48.6%) in breast cancer and ill-defined(20.5%), well-defined(73.5%), and well-defined with partial spiculation(5.8%) in fibroadenoma. The mass were grouped by size; 1-2cm(37.8%), 2-4cm(45.9%), and 4-6cm(16.3%) in breast cancer and 1-2cm(79.4%), 2-4cm(17.6%), and 4-6cm (3.0%) in fibroadenoma. On ultrasonographic study, the shape of masses in breast cancer were lobulated(82.3%),oval(14.7%), and round(3.0%),and those in fibroadenoma were lobulated(14.0%), oval(57.7%), and round(18.3%). The cases that the height was longer than width were 32.3% in breast cancer and 0% in fibroadenoma. The findings about homogenecity and echo patterns were as follows; hypoechoic(52.9%) and mixed(47.1%) in breast cancer and hypoechoic(2.8%), hypoechoic(63.4%), and mixed(33.8%) in fibroadenoma. The margin of masses were smooth in 85.9% of fibroadenoma, and irregular in 73.6% of breast cancer. The boundary echoes of masses and decreased posterior echo shadow were seen only in 61.8% and 55.9% of breast cancer, respectively. Conclusion: The margin and calcifications are more clearly delineated on mammography but breast cancer and fibroadenoma, both are more commonly developed in dense parenchymal pattern(P2+DY),and there findings are easily obscured in mammography. So ultrasoography is very useful in these masses evaluation, especially amoung young patients.
