Pathologists are at particularly high risk for blood contamination and skin injuries, so they are vulnerable to blood borne pathogens, like HIV. This article describes the first and the only one documented case of occupational HIV transmission in the world concerning American pathologist. The factors increasing the risk of contracting infection during the autopsy on the patient who has died of ...
The growing demand for the detection of prognostic and diagnostic biomarkers by application of molecular-biological techniques has been slowed down to a large degree by the use of formalin and its influence onto antigenic structures and nucleic acids, although other reasons also exist. With regard to morphology a limitation in the possibilities, compared to frozen sections, takes place. With th...
AIM To examine usefulness of virtual biopsy using endocytoscopy by comparing the in vivo endocytoscopic and histopathological images of gastric cancers. METHODS Endocytoscopy was performed in 30 patients with early gastric cancer. Of these, 26 patients showed well differentiated adenocarcinomas, while 4 patients showed poorly differentiated adenocarcinomas (including one signet ring cell carc...
Frozen section diagnosis is a highly useful method of diagnosis. There were 4434 frozen sections, 24 false positive diagnosis, 65 false negative diagnosis and 30 deferred diagnosis. This method achieves the highest accuracy when there is a cooperation between experienced surgeon and reliable and careful pathologist. It is wise to defer the diagnosis of consult to other pathologist in difficult ...
UNLABELLED Immunohistochemical (IHC) assays performed on formalin-fixed paraffin-embedded (FFPE) tissue sections traditionally have been semi-quantified by pathologist visual scoring of staining. IHC is useful for validating biomarkers discovered through genomics methods as large clinical repositories of FFPE specimens support the construction of tissue microarrays (TMAs) for high throughput st...
Adenoid squamous cell carcinoma, representing a rare histologic subtype of oral squamous cell carcinoma shares a considerable histopathological and immunohistochemical overlap with a few aggressive lesions. It is important for the pathologist to be aware of the possibilities of potentially misdiagnosing this entity. Hence, an attempt is made in this commentary, to acquaint the pathologist to th...
