Localized constriction and torsion of the umbilical cord are rare cord abnormalities. The seg- mental absence of Whartion's jelly in the involved area of the cord is believed to be an etiologic factor of the constriction and subsequent torsion. In the past, constriction and torsion were thought to occur after the death of the fetus as a result of maceration. However, recently it has been suggested that the torsion of the constricted area might cause fetal death. We report an autopsy case of a localized constriction and torsion of the umbilical cord in a stillborn baby. The baby was delivered to a 27-year-old primiparous woman after 28 weeks gestation. The fetus was of 24 gestational weeks in size and weight. And the placenta weight was 259 gm. A grossly macerated fetus showed a cystic hygroma in the posterior neck. There were two areas of constriction in the umbilical cord, one at the squamoamniotic junction and the other, 15 cm from the fetal end. Torsions were noted in both constricted areas, more severe than in the mid portion of the cord. Microscopically, the Whartion's jelly was deficient and partly replaced by fibrosis in the constricted areas. It is believed that these two areas of constrictions and torsion are causally related to the intrauterine fetal death in this case.

Sarcomatoid renal cell carcinoma is an uncommon tumor that has to be distinguished from renal carcinosarcoma. We have described three cases of sarcomatoid renal cell carcinoma showing different clinical and light microscopic features. An ultrastructural study of the tumor cells from the sarcomatoid area revealed frequent desmosomal junction, confirming the epithelial nature of the neoplasm. All three cases showed an aggressive clinical course and tended to invade adjacent organs or tissues. We believe that an histological and immunohistochemical examination in conjunction with an electron microscopic examination are necessary to diagnose sarcomatoid renal cell carcinoma.

Atresia of larynx is a rare fatal anomaly that should bring an immediate medical attention for proper managenent. We reported a case who died in neonatal period because of respiratory difficulty. His first problem was difficulty of inserting tracheal tube through the larynx. It was of interest in this case that he was presented with generalized edema and also massive lung edema. The lung was characterized by total absence of squamous and amniotic debris in the alveolar spaces and massive inflation of the alveoli by clear fluid that was thought to be amniotic fouid produced by the lung per se. Because there was no connection between oral cavity and the lungs, there would be no way the amniotic fluid outside the fetus. The laryngeal atresia was of infraglottic type and was complete with dispalced cricoid cartilage. Associated anomalies were left persistent supperior vena cava, perimembranous ventricular septal defect, spina bifida and focal cerebellar heterotopia.
