RESUMO
Amniotic band syndrome is a rare pathology which involves a group of fetal malformations due to the formation of bands between the fetus and the extraembryonic derivatives. These fetal malformations are extremely variable and their type depends upon the period of gestation during which the bands develop. In rare cases, these bands could strangulate the umbilical cord vessel and lead to fetal death. The authors report an exceptional case fo swallowing of the amniotic band by a fetus at term and fetal death due to strangulation of the umbilical cord vessels by amniotic band.

Four cases of struma ovarii were seen among 308 ovarian tumors removed surgically at the Salah Azaiz Institute, Tunis, Tunisia, between 1980 and 1989. This yields an occurrence rate of 1.3%, which is comparable to previously publishes rates (0.3% to 2%). One of the four tumors was malignant. Malignant transformation of struma ovarii is very rare (5% to 10%). The histologic diagnosis of malignancy is difficult, particularly in well-differentiated follicular forms. The prognosis is relatively favorable even in patients with metastases. Based on their personal experience and on a review of the literature, the authors discuss the diagnosis, management, and outcome of struma ovarii, in particular with malignant transformation.
