Abnormal Tissue Identification

For us in histology, normal tissue identification is typically an easy process.  As histologists, we were once required to identify all normal tissues by H&E under the microscope.

For abnormal tissue however, an H&E stained slide can be very difficult to identify tissue type and diagnosis.  That’s why when a pathologist orders multiple stains on one tissue, they are trying to get a larger picture to understand its etiology.

To help in understanding, here are 3 stains on the same tissue, H&E, SMA, & CD8 at 4x & 10x.  This is human tissue.  Can you identify this tissue and its diagnosis?

I’ll give you choices.

A. Lung – Spindle cell carcinoma

B. Liver – Cirrhosis

C. Colon – Adenocarcinoma

D. Heart – Myocardial fibrosis

NPR News Covers New Policy of University Of California on Measles

NPR covers the story of the new required policy starting 2017 for all new students attending the University of California.  This gives a microscope picture of measles stained with H&E.  This is a truly rare event where histopathology is highlighted using a micrograph.


This is a great article to draw attention to histology and how diseases like this are diagnosed.
