✦ Synopsis


In 1952, Goldenhar described a pair of monozygotic twins who were discordant for epibulbar dermoids, auricular appendages, malformations of the auricle, and hemifa-cia1 microsomia. Eighteen twin pairs have subsequently been described in which at least one member exhibited these manifestations. We report on an additional pair of discordant dichorionic monozygotic male twins. All of the 5 monozygotic twin pairs for which placental information is available have been discordant and 2 of these had dichorionic membranes. The failure of discordant monozygotic twins to be limited to rnonochorionic pairs argues against the hypothesis that developmental abnormalities arising from the placental vascular anastomoses that are commonly found in monozy- gotic twins is the probable explanation for the discordant expression of these traits in twins.

We report on a pair of monozygotic twins with persistent truncus arteriosus. They had no evident clinical signs of DiGeorge syndrome. Pathologic examination of the placenta and DNA analysis in chromosomes 7, 8, and 15 was consistent with monozygosity. Fluorescence in situ hybridization test was nega

## BACKGROUND. The sacrococcygeal area is the most frequent site of teratoma in infants, but it is a rare location for teratoma in adults. ## METHODS. The authors report two patients in their sixth decade of life with the pathologic diagnosis of sacrococcygeal teratoma. The clinical presentatio
