Q. How is it that a cytopathologist can diagnose invasive squamous cell carcinoma on a Pap smear?
I received an email yesterday that had questions about a post from a couple years ago – and rather than bury the answers way back in 2009, I thought I’d make a new post.
Most esophageal carcinomas fall into one of two kinds: adenocarcinoma or squamous cell carcinoma.
Q. When a squamous cell carcinoma is designated as “poorly differentiated”, what other parameters/tests are performed to determine the tissue of origin?
