Aplasia cutis congenita is a rare disease presenting in the newborn infant as localized areas of skin defect. Its association with a number of congenital malformations is well documented. I observed a newborn infant with typical aplasia cutis congenita. The skin defect of my case was found on the posterior fontanelle without any congenital malformation. Diagnosis was made by history, clinical and histopathological findings.

Genetic and clinical observations were recorded on 16 patients with xeroderma pigmentosum, 14 of them having visited the Department of Dermatology, Chonnam National University Hospital, Kwangju, Korea from 1968 through 1982, and 3 of them having visited the Department of Dermatology, Chosun University Hospital located in the same city during same period(one patient was duplicated). Xeroderma pigmentosum was found to occur with a frequency higher than one in 183,000 births in Chonnam province, Korea. It waa recognized that xeroderma pigmentosum is a disease of autosomal recessive inheritance. The sex ratio of xeroderma pigmentosum was male to female l. 7 to 1. The age of onset was between 5 months and 10 years, and the age when the patients visited the hospital for the first time was 6 months and 25 years. The skin malignancies were observed in 9 patients, among which squamous cell carcinomas occurred in 6, basal cell carcinomas in 2, and actinic keratosis in l. The associated ocular abnormalities were photophobia in 4 patients, chalazion in 1, blepharoconjunctivitis in 1, pterygium in 1 and squamous cell carcinomas in 1. Only cerebral galsy as a neurological abnormality was observed in 1 patient.

Breast cancer is the school most common cancer in Korea women. The incidence of breast cancer is around 25 per 100,000 women, and more than 5,500 women are diagnosed as breast cancer annually. Epidemics show that the incidence and mortality of breast cancer are increasing due to rapid changes of women's life style and westernized food and so on. The risk factors for breast cancer include hormone-related factors (early menarche, late menopause, no or late birth, hormone replacement therapy) and genetic background. It is hard to change risk factors for breast cancer but early detection strategies are best for decreasing the mortality rate from breast cancer. Breast self examination, clinical breast examination, and mammography can be used for screening of breast cancer. Breast self examination is not sensitive enough to detect a small cancer but monthly exam makes women be awakening about breast cancer and feel changes of her breast. Meta-analysis shows annual mammography reduces breast cancer mortality around 35% in the ages over 50. Some randomized clinical trials also showed mortality reduction by mammography in the ages of 40s. Surprisingly, breast cancer is rapidly increasing in late thirties with a peak incidence in forties among Korean women. Whether the early peak makes mammography less accurate is controversial. However, data from qualified screening centers showed mammography has same sensitivity with that in westerns. Korean Breast Cancer Society and National Cancer Center organized the 1st Consensus meeting for the national guidelines for breast cancer screening on July 24, 2001. We recommend that women should have monthly self examination beginning at age 30, should receive biannual clinical breast exam from healthcare providers from age 35, and should receive clinical breast exam and mammography at 1~2-year intervals after age 40.

Autograft using suction hlistered epidermis is one of the surgical therapeutic mod- alities of vitiligo, and has been successfully used by several authors. The maintenance of grafting pigment is belieued to be more important than repigmentation itself. To examine the maintenance of pigment, 22 vitiligo patients were treated by autograft using suction blistered epidermis and followed for 16.8 months. Repigmentation developed in 20 patients, Two patients were lost to follow up. Out of 20 patients, grafting pigment was maintained in 17 patients(85% ) and disappeared in three patients(15% ). By clinical subtype, the rates of maintenance were 100% in segmental type, 80% in localized type and 66% in generalized type. The best results were observed in a head and neck location and the worst rates and maintenance were in the hand. However, these differences were not statistically significant. likewise, age and sex were not factors in maintenance and repigrnentation. Based on this study, autograft using suction blistered epidermis appears to be a good therapeutic modality for stable vitiligo, particularly segmental vitiligo.

Dysplasia Epiphysealis Hemimelica is a rare developmental disorder of epiphyseal growth characterized by asymmetrical cartilagenous overgrowth. This disorder was first described with the “la tarsomegalie” by Mouchet and Belot in 1926 but this name, Dysolasia Epiphysealis Hemimelica, was first proposed by Fairbank in 1956. This disorder is usually limited to either the medial or lateral half of a single extremity in childhood. It is asymptomatic until the protruding epiphyseal mass interferes joint function. The character istic abnormalities are deformities, restricted motion and pain. The most frequent finding at the initial examination is an irregular, often multicentric radiopacity, and when the lesion is matured it looks irregular, and frequently there is a lobulated osseous mass protruding from the epiphysis of tarsal and carpal bones. Diagnosis by the roentgenogram requires primarily knowledge of this condition. The lesion is often microscopically indistinguishable from an osteochondroma. A case of Dysplasia Epiphysealis Hemimelica in a 17 year old male, showing typical roentgenographic appearances, is reported together with a brief review of literature in this paper.

BACKGROUND: Sunscreens have been used widely to prevent the photosensitive skin diseases, skin cancer, and skin aging. However, no sunscreen blocks all kinds of effects caused by ultraviolet light(UVL), and the effect of sunscreens on the impairment of immune function by UVL irradiation is controversial. OBJECTIVE: We try to evaluate the efficiency of sunscreens for blocking the depletion of LC induced by UVB irradiation. METHOD: The ATPase positive LCs were observed in the skin of hairless mice(Hr+/Kud) irradiated by UVB with or without topical application of sunscreens. Two commercially available sunscreens with respective SPF 8 and SPF 30 were applied to the dorsal trunk skin. The mice were irradiated with different increasing doses of UVB at a single time. RESULTS: The ATPase positive LCs in the irradiated dorsal and ear skin were significantly de-creased in densities according to the dosage, and apparently revealed a loss of their dendrites, granulation, and clumping from a UVB dose of more than 60mJ/Cm2. With both sun-screen treatment on the dorsal trunk before irradiation, the densities of LCs on the dorsal skin were significantly higher compared to the un-treated groups at all ranges of UVB doses in spite of a dose dependent decrease in their density. However there was no significant difference on their preventive effect between both sunscreens(SPF 8 and SPF 30) except at high UVB dos-es of more than 240mJ/Cm². CONCLUSION: The LC depletion induced by UVB can be partially protected through the topical application of a sunscreen at a UVB dose dependent fashion. However SPF(sun protective factor) dose not appear to be a good indicator for evaluating sunscreens immunologically.

T cell lymphoblastic lymphoma is characterized by immature lymphoid cells that are indistinguishable from the lymphoblasts and prolymphocytes of acute lymphoblastic leukemia. Several characteristic clinical features of lymphoblastic lymphoma, with include a high male-to-female ratio, a relatively high incidence in older children and young adults, the frequent presence of mediastinal involvement at the time of diagnosis. Also, this disease is rapidly progressive, and early dissemination to the bone marrow, blood, and central nervous system leads to the evolution of a picture resembling a acute lymphoblastic leukemia. We have experienced a rare case of congenital T-cell lymphoblastic lymphoma in which 1/365 year old female newborn had generalized multiple irregular protruding mass on her body. On bone marrow biopsy, CSF analysis, ultrasonogram and whole body MRI studies. We found metastasized tumor mass to, orbit, abdominal cavity, bulva, skin, and lower extremities. Histopathologically, specimen from mass on the right thigh showed diffuse infiltration of poorly differentiated and immature lymphoid cells in the skelectal muscle and subcutaneous soft tissue. By immunophenotyping studies using anti T cell and B cell monoclonal antibody, these cells were reactive with UCHL-1, MB2, but unreactive with MB1, L26. Based on these findings, the lesion was diagnosed as lymphoblastic lymphoma of the T-cell type, which occurred congenitally. Most T cell lymphoblastic lymphoma are noted, but congenital case was not reported. So we report it with a brief review of literature.

PURPOSE: To evaluate the role and difficulties of the use of routine abdomen ultrasound (US) in postoperative breast cancer patients. MATERIALS AND METHODS: We reviewed the clinical records of 2460 patients who received breast cancer surgeries and underwent routine follow-up abdomen US for more than five years. We evaluated the number and clinical conditions of patients with a liver metastasis. We also evaluated the cut-off point of the breast cancer stage where a metastasis was likely to occur using the chi-squared test and receiver operator characteristic (ROC) analysis. RESULTS: A metastasis developed in 238 patients (9.7%), and the liver was the third most common organ site. However, just 24 (0.98%) patients presented only with a liver metastasis. Among these 24 patients, a metastasis was detected in 17 patients with the use of routine abdomen US. The cut-off point for a metastasis was Stage 3A. CONCLUSION: The use of routine screening abdomen ultrasound for the detection of a liver metastasis in postoperative breast cancer patients is not recommended. However, US can be used selectively in patients with clinical symptom or that present with a high stage equal or greater than Stage 3A.
