We present a case of eccrine spiradenoma occurring on the trunk in a 33 year old woman. She developed a pea sized, pinkish tender nodule on the anterior chest 8 years ago. On histologic examination, there were several lobules surrounded by thin connective tissue septa in dermis. The lobules themselves consisted of small dark staining cells and large pale-staining cells, forming solid cords or ducts.

Angiosarcoma is a rare malignant vascular tumor of endothelial cell origin. Most lesions of cutaneous angiosarcoma occur over the face and scalp. We experienced a case of angiosarcoma of the scalp in a 63-year-old man. Multiple pea-sized erythematous papules and nodules developed on the forehead 6 months ago. Thereafter, the lesions have extended to make violaceous, compressible and hemorrhagic plaques. On histologic examination, there were irregular, often anastomosing vascular channels lined by the atypical endothelial cells in the dermis.

PURPOSE: The differentiation between renal cell carcinoma(RCC) and transitional cell carcinoma(TCC) is important due to the different methods of treatment and prognosis. But occasionally it is difficult to draw a distinction between the two diseases when renal parenchyme and renal collecting systems are invaded simultaneously. MATERIAL AND METHOD: We reviewed CT scans of 37 cases of renal cell carcinoma and 12 cases of transitional cell carcinoma which showed involvement of renal parenchyma and renal sinus fat on CT. Retrospective analysis was performed by 3 abdominal radiologists. Check points were renalcontour bulging or reniform shape, location of mass center, intact parenchyme overlying the tumor, cystic change, calcification, LN metastasis, vessel invasion, and perirenal extention. RESULT:There were renal contour bulging due to the tumor mass in 33 out of 37 cases of renal cellcarcinima, wherea and nine of 12 cases of transitional cell carcinoma maintained the reniform appearance. This is significant statiscal difference between the two(p<0.005). Center of all TCCs were located in the renal sinus, and 24 out of 35 cases of RCC were located in the cortex(p<0.005). Thirty-six out of 37 cases of RCC lost the overlying parenchyma, whereas 4 out of 9 cases of well enhanced TCC had intact overlying parenchyma(p<0.005) RCC showed uptic change within the tumor mags in 31 cases which was significanity higher than the 4 cases in TCC(p<0.05). CONCLUSION: CT findings of renal cell carcinoma are contour bulging, peripheral location, obliteration of parenchyma, and cystic change. Findings of transitional cell carcinoma are reniform appearance, central location within the kidney, intact overlying parenchyma, and rare cystic change.

The pulmonary cytology has reached a high level of accuracy. By the examination of the sputum and/or bronchial brushings, it is now possible to make a diagnosis in 70% to 90% of patients with cancer. Primary melanoma of the lung is very rare and there have been reported about 20 cases in the world literature. We present a case of primary malignant melanoma of the lung in a 61-year-old male diagnosed by cytologic examination of sputum, bronchial brushing and aspirated pleural fluid. Histologic examination of bronchoscopic biopsy and examination of the skin and other primary sites confirmed the diagnosis.

We experienced a case of congenital rubella syndrome manifesting patent ductus arteriosus, petechiae, microcephaly, intrauterine growth retardation, and hepatomegaly in one-day-old female newborn infant. Congenital rubella syndrome was confirmed by positive results of anti-rubella IgM in the sera of patient. Anti-rubella IgM was negative in the sera of mother, while anti-rubella IgG was positive.

We observed the neonatal skin to investigate the incidence and clinical features of birthrnarks. We examined 1791 newborn babies admitted in the nursery of Kangnam Sacred Heart Hospital from July 1987 to July 1989. The results were summarized as follows. 1. Mongolian spots were observed in 1435 neonates (80.1%), occurring most frequently on the lumbosacral area. 2. Salmon patches were observed in 416 neonates (23.2%), the nape of neck being the most common site. 3. Pigmented lesions were observed in 20 neonates (1.1%). 4. Portwine stains were observed in 15 neonates (0.8%). 5. Epidermal nevi were observed in 4 neonates (0.2%) and nevus sebaceus developed in one baby.

BACKGROUND: Pregnancy in human and rodents is associated with dramatic matemal metabolic changes. Insulin-like growth factors (IGFs) are mitogenic peptides that are essential for fetal and maternal tissue growth during pregnancy. They circulate complexed primarily with a serum IGF-binding protein (IGFBP-3) which regulates the availability of the IGFs to their specific target tissues. METHODS: To examine the changes of IGFs and IGFB-3 during pregnancy, we measured serum total IGF-I, free IGF-I, IGF-II and IGFBP-3 by using specific radioimmunoassay, immunoradio-metric assay, western ligand blot and western immunoblot. Blood samples were obtained from 88 pregnant women between 6-40 weeks gestation. RESULTS: While serum IGF-I levels increased up to 50% in late pregnancy, serum IGF-II levels remained unchanged. However, serum free IGF-I levels were significantly higher during pregnancy than in nonpregnancy. Western ligand blot analysis revealed that IGFBP-3 in pregnancy serum was significantly decreased at 6 weeks of gestation, continued decreased level until term, and returned to a nonpregnant level by postpartum 10 day. Serum IGFBP-3 profiles in Western immunoblot analysis revealed that 30 kDa fragments of IGFBP-3 were detectable in pregnancy serum but not in nonpregnancy serum. In contrast, serum IGFBP-3 levels using radioimmunoassay was significantly increased in late pregnancy. CONCLUSIONS: 1) serum IGF-I was significantly elevated in late pregnancy 2) serum IGF-II was not significantly changed 3) free IGF-I significantly elevated throughout gestation 4) intact IGFBP-3 was markedly reduced after 6 weeks of gestation.
