The diagnosis was made on microscopic evaluation of gastroscopic biopsy specimens.
It is primarily based on microscopic evaluation of tissue samples, which most often begins with evaluation of image-guided core biopsies obtained by radiologists.
Only two cases have been reported in which the diagnosis of gastric actinomycosis was made on microscopic evaluation of a gastroscopic biopsy specimen [ 6, 8].
According to traditional definition, architectural integrity is disrupted during pathogenesis of epithelial tumors and pathological assessment is based predominantly on microscopic evaluation of (loss of) epithelial cell features [ 11, 29].
The existing screening programmes are based on the microscopic evaluation of liquid based cytology and despite a high specificity of 95 to 98%, sensitivity varies from 74 to 96% [ 19, 20].
Cytospin preparations were stained with a HEMA 3 stain set (Fisher Scientific, Pittsburgh, PA, USA), and broncho-alveolar lavage (BAL) fluid cell differential percentages were determined based on light microscopic evaluation of >300 cells/slide 29.
The pathological changes in the brain and spinal cord of mice were observed by light microscopic evaluation of H&E stained tissues on Day 18 and Day 40 PI.
Therefore, the presence or absence of lung metastases was based on macroscopic and microscopic evaluation of the lungs.
