BACKGROUND: Vitiligo is considered as an autoimmune disorder due to the generation and presence of autoantibodies directed against melanocyte antigens in the patients sera. Previous studies have revealed an increased incidence of organ-specific autoantibodies in vitiligo patients. A number of studies have demonstrated an increased frequency of thyroid autoantibodies in vitiligo patients and vitiligo is commonly seen in patients with clinical thyroid diseases. OBJECTIVE: The aim of this study is to investigate the incidence of antithyroid antibodies in vitiligo patients and to correlate the presence of these antibodies with factors such as sex, age, activity of the disease, duration of the disease and the type of vitiligo. Another aim of this study is to compare the incidence of abnormal thyroid function in those who have antithyroid antibody and those who don't. METHODS: One hundred and fifty seven vitiligo patients who visited vitiligo clinic in Samsung medical center from January of 1995 to November of 1996 were enrolled in this study. Detection and titration of antithyroid antibodies were performed by immunoradiometric assay. RESULTS: Among 157 patients tested, 17(10.8%) patients had antithyroglobulin antibodies and 10(6.4%) patients had antimicrosomal antibodies. Five patients had both antibodies. Statistically meaningful data are as follows; 1) Antimicrosomal antibody appeared less frequently in patients of childhood-onset. 2) Antithyroglobulin antibody was detected more frequently in active disease. Fifty nine out of 157 patients were examined for thyroid function. Four out of 22 patients with antithyroid antibody had abnormal thyroid function. None out of 37 patients without antithyroid antibody had abnormal thyroid function. CONCLUSION: The incidence of antithyroid antibodies according to onset age and activity is contradictory to previous reports, therefore large scaled study will be necessary to draw a conclusion.

PURPOSE: Nodal involvement has long been known to represent the single most reliable indicator of the prognosis for early-stage breast cancer. In common parlance, high-risk node-positive breast cancer has generally been used to describe patients who have involvement of ten or more axillary lymph nodes (10+LN). Breast cancer patients who had 10+LN clearly have a strikingly high risk of tumor recurrence and death. Thus we tried to evaluate the clinical courses of breast cancer patients who had more than 10 positive axillary lymph nodes. METHODS: Of the 587 breast cancer patients who were operated on at Chungnam National University Hospital from February 1992 to November 1999, 31 cases (5.3%) showed involvement of more than 10 axillary lymph nodes. We evaluated the clinical courses of these patients and the differences in survival according to the clinical and pathologic vaiables. Survival was calculated using the Kaplan-Meier method. RESULTS: The mean age of the patients was 50+/-4 years. A mastectomy was done in 28 cases (90.3%), and a breast conserving operation was done in 3 cases (9.7%). The mean tumor size was 4.8+/-.5 cm. The mean number of removed axillary Lymph Nodes was 23.5+/-0.2 (range:10-52), and the mean number of positive axillary LNs was 20.0+/-10.1 (10-51). At a median follow-up of 30.5 months, 23 cases (74.2%) of recurrence were noted. Among these 23 cases (69.6%) showed distant metastases as the first recurrence. The 3-year and 5-year disease-free survivals were 28.6% and 22.9%, respectively. The 3-year and 5-year expected overall survivals were 53.7% and 41.8%, respectively. There were significantly more recurrences in patients who had given up taking their adjuvant chemotherapy than for those patients who had completed 6 cycles of FEC or MMM. Also, significant survival benefits were noted in those patients who were treated using a combination chemotherapy with taxane plus cisplatin after their tumor recurrence. CONCLUSION: Breast cancer patients with 10+LNs have a strikingly high risk of tumor recurrence. Six cycles of adjuvant chemotherapy with FEC or MMM was a controllable variable for lowering the risk of tumor recurrence. A combination chemotherapy with taxane and cisplatin was also a controllable variable for increasing survival after tumor recurrence.

PURPOSE: The purpose of this study was to describe the clinical and imaging features of metastatic bone tumors with sunburst periosteal reaction and to define the characteristic findings which would be helpful for differentiating metastatic bone tumors from primary malignant bone tumors. MATERIALS AND METHODS: The authors retrospectively reviewed the cases of nine patients with pathologically confirmed metastatic bone tumors with sunburst periosteal reaction, for which imaging studies (plain radiographs [n=9], radioisotope [RI] scans [n=4], magnetic resonance [MR] images [n=6], and computed tomographic [CT] scans [n=4]) were performed. The imaging studies of each lesion were analyzed by two musculoskeletal radiologists focusing on the metastatic site, patterns of bone response, signal intensity characteristics and pattern of contrast enhancement on MR. The clinical records of the patients were reviewed with regard to the age and sex of the subjects, the clinical presentation, and the origin of the primary tumors. RESULTS: The cases consisted of six men and three women, whose mean age was 62 years (age range, 50-88 years). The primary tumors were adenocarcinoma of the stomach [n=4], adenocarcinoma of the lung [n=2], adenocarcinoma of the prostate [n=1], hepatocellular carcinoma of the liver [n=1], and adenocarcinoma of unknown origin [n=1]. The sites of metastatic involvement exhibiting sunburst periosteal reaction were the scapula [n=2], proximal humerus [n=2], rib [n=1], iliac bone [n=1], tibia [n=1], spine [n=1], and proximal phalanx [n=1]. In all patients, the imaging findings showed osteolytic [n=3] or osteoblastic [n=6] lesions with sunburst periosteal reaction. In six cases, the lesions were iso-intense on the T1-weighted images and heterogeneously hyperintense on the T2-weighted images. The gadolinium-enhanced T1-weighted images showed a nearly homogenous enhancement of the lesions without any central necrotic portion. CONCLUSION: Although metastatic bone tumor exhibiting sunburst periosteal reaction is rare, it should be included along with primary malignant bone tumors in the differential diagnosis of bone lesions with sunburst periosteal reaction, especially in older patients with or without a known primary malignancy.
