air-filled cushions distribute pressure extremely well, but some models provide little stability.
Imagine the following: without any universally agreed quantitative guidelines, how do we distinguish "subtotal" from partial villous
(2-4) Early CHMs are characterized by a redundant bulbous villous
growth pattern, hypercellular myxoid villous
stroma, a labyrinthine network of villous
stromal canalicular vascular structures, karyorrhectic debris within stroma, and at least focal trophoblastic hyperplasia on villi and the undersurface of the chorionic plate.
Many investigators believe that this lesion is due to replacement of the villus by fibrin, this being formed either from the maternal blood in the intervillous space or from the fetal blood in the villous
was used : epithelial damage overlying the villi and reduction in the villous
depth, inflammation in the ileum lamina propria and serosa, and hemorrhage in the ileum were evaluated.
Celiac disease is a close differential for CVID enteropathy, with both entities showing intraepithelial lymphocytosis and villous
The positive diagnosis of CD was based on the presence of characteristic duodenal enteropathy, which can range from intraepithelial lymphocytosis (LIEs) to total villous
flattening; positive serology for specific antibodies, mainly those directed against type 2 tissue transglutaminase (tTG); and CD-associated symptoms.
The number of vascular channels present in terminal villi ranges from 2 to 6 and if the number increases beyond this then it is termed as 'villous
hypervascularity (1).' The term 'chorangiosis' was introduced by Altshuler in 1984 and is defined as the presence of [greater than or equal to]10 terminal villi, each containing [greater than or equal to]10 capillaries per terminal villus in [greater than or equal to]10 low power (10x) fields in at least 3 or more random, non-infarcted cotyledons of the placenta (2).
The chorionic veins are direct continuations of the veins of the villous
trees (stem villi, attached to the plate that reaches the cotyledon) and usually crosses underneath to the chorionic arteries.
adenoma of the appendix: a case treated with sequential endoscopic-minimal surgical technique.
adenoma of extrahepatic bile duct: contrast enhanced sonography findings.
Five villi and crypt areas were systemically chosen per sample for villous
height and crypt depth measurement.
In order to be able to reliably evaluate the villous
maturation of the placenta, the pathologist was only informed about the gestational age.
It also showed subendothelial fibrin deposition in stem villous
blood vessels, chorionic villous
hypervascularity, and a small subchorionic placental infarct.
Placental examination showed placentomegaly with villous
hydrops, fetal erythroblastosis, and infiltration of villous
stroma by aforementioned histiocytic cells (Figure 2).
