Pathologists generally submit "background blocks" of macroscopically
normal tissue from excision specimens.
In this pilot experiment, we aimed to determine two endpoints: 1) Does IRE affect iatrogenic material macroscopically
and microscopically, and 2) does iatrogenic material affect the IRE ablation zone?
All cases of incidental GBC in these studies had a macroscopically
abnormal gallbladder; hence, these studies suggest that it is safe to adopt a selective approach to HPE.
Microscopically, lipid containing histiocytes infiltrating into outer muscle layer of gall bladder wall may be seen to from xanthogranulomatous foci and fibrosis owing to extravasation of bile into gallbladder wall through Rokitansky-Aschoff sinuses or a small ulceration in the mucosa.3 Macroscopically
, XGC lesion vary from yellowbrown nodules in the gallbladder wall to diffuse involvement of the entire gallbladder with extension to the surrounding structures.4 The importance of XCG is that it mimics gallbladder carcinoma (GBC) preoperatively on imaging and intra-operatively.
, the tumor mainly contains four patterns as follows: papillary, sclerotic, solid, and hemorrhagic.
For example, in one location in December 2001 prevalence in surface animals was 100%, and 83% of those animals contained macroscopically
visible mantle nodules; samples of animals buried in the underlying sediment showed a 12% prevalence with only 2% containing macroscopically
visible mantle nodules.
Her idea for Youth Forum finale is to develop a solar powered water bottle that does two things: purifies dirty water (both microscopically and macroscopically
) and condenses atmospheric water vapor to drinkable water.
In our study also, only 2 out of 9 (22.22%) unexpected pathologies could be identified macroscopically
and the rest 7 would have been missed if they had not been subjected to routine examination.
The tumor was macroscopically
bright and had a soft, gelatinous structure.
The parasite attaches itself to fish with an anchor, feeding on fish blood and tissue debris in this way, and macroscopically
, causing the loss of scales, oedema on the skin, haemorrhages and deep ulcers and, thus, the parasite forms routes of entry for other pathogen such as fungi and bacteria causing secondary infection (8,12).
In all cases, the lesions were well-defined, dry-looking, erythematous plaques macroscopically
(Figure 1, 2).
Two drops of the AHG reagent were then added to the dry cell button in the tubes, before being centrifuged and resuspended by agitation and read macroscopically
. If the test was negative, one drop of Coombs reagent was added to the cells, which were then centrifuged and analyzed for agglutination.
