Epidermal cyst in the fibroadenoma of the breast is very rare. A 29-year-old woman presented with a lump in the upper outer quadrant of the right breast. Clinically it was a fibroadenoma and the excisional specimen showed an encapsulated, firm lobulated lesion with a cystic area on cut surface. The cystic area showed squamous metaplasia of the ductal epithelium and keratinous cyst formation in the fibroadenoma. We report this unusual case with review of literatures.

PURPOSE: The incidence of clinical nephritis is much higher especially in younger ages and in about one half of the cases, it also shows nephrotic syndrome. Thus, we examine the clinical and pathologic consideration of children with lupus nephritis and their treatment modality to improve the prognosis. MATERIAL AND METHOD: Among 67 cases of children under eighteen who were diagnosed SLE, 50 patients with hematuria and proteinuria from Jan. 1980 to Dec. 1996 were selected for the review. RESULTS: The ratio of the male to female patient was 1:3.5 and the average age at the diagnosis was 11.85+/-3.2 years old. Most common clinical manifestations at the time of the diagnosis were fever and skin rashes and the common laboratory results were proteinuria, hematuria, Out of 50 cases, 33 cases had renal biopsy. The results were 17 cases of Class IV, 7 cases of Class lll, 5 cases of Class lll, 3 cases of Class V and 1 case of Class l. Different treatment modalities were carried out; Corticosteroid only 21 cases, Corticosteroid+Azathioprine 25 cases, Corticosteroid+Cyclophosphamide 3 cases, and Corticosteroid+Cyclosporine A 1 case. However, there were no significant difference in the recurrence and complete remission rate of lupus nephritis in between each treatment groups. Average follow-up period was 37+/-23 months. Of all the follow-ups, 7 patients were dead. CONCLUSION: Early diagnosis should be carried out with renal biopsy, and should be considered for vigorous therapy, which currently includes high doses of corticosteroids and immunosuppressive drugs. Among these immunosuppressive agents, azathioprine has a lower incidence of long-term complications and low costs might be recommended. In addition, regular check-up for anti-DNA antibody, serum complement concentration and appropriate moniroting and management for the adverse effects of the treatment should enable to reach the continuous remission.

Trichilemmal horn(trichilemmal keratosis) is a rare keratinizing tumor that resembles a cutaneous horn. Histologically, it is characterized by an abrupt maturation of keratinocytes into lamellar keratin without the formation of a granular layer. We describe a case of a trichilemmal horn on the right cheek of a 78-year-old woman.

BACKGROUND: Nonalcoholic fatty liver disease (NAFLD) is associated with metabolic syndrome including insulin resistance, hypertension, dyslipidemia, central obesity, type 2 diabetes, and cardiovascular disease. In NAFLD, insulin resistance plays an important role in the progression of liver damage. In this study, we evaluated insulin resistance, plasma adiponectin, hepatic steatosis, and their association in adults with normal liver transaminase concentrations. METHODS: We analyzed 111 subjects, aged over 20 years old, who visited the Health Management Center at Chung-Ang University Hospital between May 2006 and August 2006. They had neither history nor clinical evidence of diabetes, cardiovascular or liver disease. They were divided into three groups by the degree of hepatic steatosis based on ultrasound findings. Anthropometric parameters were measured and blood samples were drawn after eight hours of fasting. RESULTS: Hepatic steatosis had a positive correlation with body mass index, waist circumference, blood pressure, triglycerides, HOMA-IR, and QUICKI. Moreover, it had a negative correlation with high-density lipoprotein cholesterol and adiponectin. Triglycerides, Adiponectin, and QUICKI were independent variables in predicting the degree of hepatic steatosis. CONCLUSION: This finding suggests that triglycerides and plasma adiponectin are independent predictors of hepatic steatosis in adults with normal liver transaminase concentrations.

Invasive pulmonary aspergillosis (IPA) has been known to occur in immunocompromised patients, but has been rarely reported in immunocompetent patients. In immunocompetent patients, pulmonary fungal infections are not initially considered. This results in diagnosis and treatment delays, as well as poor prognosis. We report a case and serial CT findings of IPA in an immunocompetent 29-year-old male after congenital heart disease surgery.

Purpose: We evaluated a new color vision test, thus the ColorDx Cone contrast test HD ([CCT-HD]; Konan Medical, Inc., Irvine, CA, USA) in normal and color vision-deficient (CVD) eyes of Koreans. Methods: The CCT-HD was performed on 66 healthy Koreans (125 normal eyes) and 25 patients (50 eyes) with congenital CVD. The results from normal eyes were compared and analyzed in terms of binocular agreement, patient ages, and spherical equivalents. The CCT-HD results on CVD eyes were compared and analyzed. Results: We found no significant difference in any of the long (L), medium (M), or short wavelength (S) cone cell sensitivity (L-CCT, M-CCT, S-CCT) scores for normal eyes; also, there was no significant effect of age and no significant correlation between the spherical equivalent and the CCT score. In normal eyes, all scores were >75 (normal ≥75). The average protan L-CCT score was significantly reduced (13.0 ± 13.2; p < 0.001) as was the average deutan M-CCT score (31.7 ± 16.6; p < 0.001). The CCT-HD L-CCT and M-CCT exhibited 100% sensitivity and specificity in terms of diagnosing protans and deutans respectively. Conclusions CCT-HD allows classification and quantitative evaluation of protans and deutans, and is thus useful when examining color vision status.

PURPOSE: To report two cases with recurrent involvement of the optic nerve as the initial sign of acute leukemic relapse.CASE SUMMARY: An 8-year-old male with acute lymphoblastic leukemia on the maintenance chemotherapy was referred for a decrease in visual acuity in the right eye. The visual acuity and optic disc swelling were completely resolved with high-dose steroid therapy. Two months after the initial presentation, the symptoms recurred and brain/orbit magnetic resonance imaging (MRI) showed high intensity along the right optic nerve from the retrobulbar area to the optic chiasm. The visual acuity was restored after high-dose steroid therapy. One month after the second attack, the symptoms recurred and the cerebrospinal fluid cytology was positive for lymphoblasts. Three weeks after the intrathecal chemotherapy, the visual acuity improved fully, but optic disc atrophy developed. A 45-year-old male, who received allogenic peripheral blood stem cell transplantation for acute myeloid leukemia, presented with a decrease in visual acuity in the left eye. The left optic disc swelling improved with high-dose steroid therapy, but the medication was restarted due to the recurrence of symptoms 3 weeks later. Brain MRI showed a mass lesion compressing the left optic nerve, presumed to be a myeloid sarcoma. One month after local irradiation, the visual acuity was no light perception in the left eye.CONCLUSIONS: In patients with a prior history of acute leukemia, the recurrent involvement of the optic nerve should be considered as a central nerve system relapse, regardless of improvement with steroid treatment.

PURPOSE: The purpose of this study was to develop in vivo dosimetries using both chromosomal aberrations and micronuclei in mice to assess biological effects of radiations. MATERIALS AND METHODS: Five each mice were irradiated with 0, 1, 2, 3, 4, 5, 10 Gy of Cs-137 gamma-rays. We scored numbers of chromosomal aberrations in metaphase spreads and numbers of micronuclei in bone marrow smears under light microscope, and obtained the dose-response relationships. We also examined the relationship between the two dose-response curves. RESULTS: The frequency of both chromosomal aberrations and micronuclei increased with dose, in a linear-quadratic manner. The delta, beta, and alpha coefficients were 0.0176, 0.0324, and 0.0567 for metaphase analysis (r=1.0, p<0.001) and 0.0019, 0.0073, and 0.0506 for micronuclei assay (r=1.0, p<0.001). The frequency of chromosomal aberrations and micronuclei in diffirent radiation doses was significantly correlated (r=0.99, p<0.01). CONCLUSION: In vivo dosimetry using either metaphase analysis or micronucleus assay was feasible in mice. These methods could be useful to evaluate biological effects of radiation.
