Sonographic Evaluation of the Yolk Sac
Journal of Ultrasound in Medicine, 2012This pictorial essay aims to inform related clinicians by summarizing the normal and abnormal sonographic findings of the yolk sac in the first trimester of pregnancy. An abnormality in the sonographic appearance of a yolk sac can predict subsequent embryonic death or abnormalities. Therefore, the accurate recognition of normal and abnormal sonographic

SummaryWithin the last two years we have seen four examples of a highly malignant neoplasm in young patients for which the name yolk sac tumour is recommended. We now describe the pathology and discuss the histogenesis of these tumours. The collection of information about them is impeded by the variety of names applied to them.

The ultrastructure of feline yolk sacs from 11 stages between the 14th and the 66th day is described with reference to the endoderm and the mesothelium; supplementary histochemical and cytochemical studies are included. Despite the absence of yolk, the endodermal epithelium shows a high degree of differentiation and activity, especially in the period ...

Pure Yolk-Sac Tumor of the Lung
Asian Cardiovascular and Thoracic Annals, 2008Primary germ cell tumors of the chest often localize in the anterior mediastinal compartment. Such tumors originating from lungs and pleura are rare. Chest tomography revealed a mass in the middle lobe of the right lung in a 25-year-old man. A middle lobe medial segmentectomy was performed, and chemotherapy was applied postoperatively.

The human yolk sac and yolk sac carcinoma. An ultrastructural study.
Human pathology, 1977The ultrastructure of the yolk sac of a 39 day old human embryo was studied. The subcellular organization was suggestive of a highly specialized absorptive function proceeding in an exocelomic-viteline direction. These findings, compatible with intense metabolic activity, are at variance with the concept of rapid involution of the yolk sac following ...

Yolk sac fluid and yolk sac membrane enzymes in the marsupial, Macropus eugenii
Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1974Abstract 1. 1. Yolk sac membrane incorporated radiocarbon into hexose phosphates, amino acids and several intermediates of the glycolytic pathway and tricarboxylic acid cycle. Yolk sac fluid likewise incorporated radiocarbon, but into fewer compounds. 2. 2.
