Therefore, specimens with fragmentation, those lacking preserved tissue architecture, and specimens with scant material were not included.
Still, scant specimens are important factors in "indeterminate" cytology diagnosis.
Semi-quantitative enumeration was reported for 94 specimens; 48 (51%) scant, 34 (36%) moderate and 12 (13%) heavy colonisation.
The rate on invalid results was very low (4.8%) and due to scant FFPE specimens.
"Low" level cellularity included cases described as having a scant or paucicellular specimen per the cytology report.
Although some of these groups are known from scant fossil material, or in some cases a single specimen, it appears that gigantism has evolved a number of times in cephalopods.
Hematoxylin-eosin stained images of the specimens revealed small, round tumor cells arranged in solid sheets with scant cytoplasm, a high nuclear/cytoplasm ratio and indistinct cell borders.
The Jehol itself is replete with huge numbers of birds, but before that the avian record is very scant and the only obvious material is the famous Archaeopteryx specimens of Germany.
A fine-needle aspiration biopsy specimen of the liver showed a diffuse proliferation of anaplastic cells with hyperchromatic nuclei and scant cytoplasm, suggesting undifferentiated carcinoma of the liver.
For FNA specimens, the distinction between adenocarcinoma (ADC) and squamous cell carcinoma (SqCC) can be challenging due to scant tumor tissue [16-19] [16-19]erandother factorseveral as an otherring tumor diathesis, crushing and drying preparation artifactors19-21].
A significant number of diagnostic samples are derived from biopsy specimens; hence the molecular method must be adequately robust and sensitive to provide reliable results from scant patient material.
