OBJECTIVE: To evaluate the maternal complications and perinatal outcomes in twin pre-gnancies with one fetal demise PATIENTS: From January 1990 to December 1996, 20 twin pregnancies with single fetal death were observed in Seoul National University Hospital : in 6 cases(group 1) between 20 ~26 weeks and in 14 cases(group 2) after 26 weeks gestation by gestational age of fetal death ; in 7 cases of monochorionic and in 13 cases of dichorionic placentation. RESULTS: The incidence of one fetal death was 5.4% in twin pregnancy. Diagnosis-to- delivery interval of group 1 was longer than group 2(61.0 days : 8.9 days). So it was thou- ght that the gestational age of delivery in group 1 was not always earlier than in group 2. And other parameters(chorionicity, preterm delivery, cesarean section, coagulopathy, IUGR, perinatal mortality, neurologic sequelae, IVH) didn't show the statistical differences between group 1 and group 2. According to chorionicity, it seemed that the perinatal mortality rate of monochorionic group was higher than dichorionic(86% : 62%) and that cesarean section rate was higher in dichorionic group(54% : 14%). But there were no statistical significances between two gruops. All other parameters also didn't show differences statistically. CONCLUSION: We fail to demonstrate that monochorionic placentation is associated with increased risks for the survivor in twin pregnancies of single fetal demise. It may be part- ially explained due to small numbers of cases in this study.

Oncogenous or tumor-induced rickets is recognized as Vitamin D-resistant hypophosphatemic rickets that heals after excision of a coexisting tumor in either bone or soft tissue. Its pathogenesis is not clarified, but it has been suggested that the tumor elaborates a homoral substance inhibiting tubular reabsorption of phosphate or that the tumor inhibits the synthetic process of 1, 25-dihydroxcholecalciferol. We present two cases of vitamin D-resistant rickets, one associated with intrasseous well-differentiated osteosarcoma in the pelvis and the other associated with fibrosarcoma of distal femur. The case with low grade osteosarcoma showed immediate improvement of rickets after excision of the tumor, but the case with fibrosarcoma showed no improvement after amputation and was fatally terminated 5 months later due to lung metastasis.

A case of Dariers disease was presented and the literatures were reviewed. The patient was 20 year old male whose skin lesions revealed normal skin colored, dirty, scaly, keratotic papules with mild itching on face, anterior chest, back, abdomen, axillae, groins and flexural surfaces of extremities. They had a tendency to aggrevate in summer and improve in winter. Histopathologically, suprabasal lacunae, hyperkeratosis, papiIIomatosis, moderate degree of acanthosis and corps ronds in Iacuna were demonstrated in the epidermis. Dermal papillae surrounded with single layer of basal cells proliferated inta the lacunae. Upper dermis revealed mild nonspecific inflammatory cell infiltrates.

Majocchi's disease is one of chronic vascular disorders of the skin, histologically showing capillaritis with lymphoid cell infiltration. Although the hypothesis of delayed type hypersensitivity reaction against foreign antigen is proposed as the mechanism producing this condition, there are much yet to be defined. We tried to examine the lesional skin of five patients with Majocchi's disease by the direct immunofluorescence with anti-human immunoglobulins, C 3, and fibrin. As a result we found the deposition of immunoglobulins (M, and G) in papillary blood vessels in four patients, and C 3 and fibrin were found in all five patients. C3 was also found at the dermoepidermal junction in three patients. These findings suggest the posssibility that antibody mediated immunologic processes may alsobe involved in the pathogenesis of this disorder. With this observation Majocchis disease could be considered as a chronic immune vasculitis.
