Melanin or Melanoma?

Human skin (melanoma?) H&E

Melanoma, a heightened subject that should be talked about with, everyone?  How do you tell the difference between melanin and melanoma?  Research facilities are currently exploring this topic and it’s treatment.  But we do know the primary cause, too much UV rays.  The pathologist can see the difference between melanin and melanoma an H&E stained section, can you?.  Here are some examples.

For the rest of us, melanoma is better detected by antibody staining (IHC).  There are a few different antibodies, MART1, Melan, HMB but all I have is Granzyme B.

What do you think?

Ovarian Carcinoma

In this tissue, it’s diagnosis is ovarian carcinoma.  It’s stained with H&E and pictures taken at multiple areas.  Some (not posted here) look to have melanin deposits but that will have to be discovered using different staining techniques and will update again here.

Enjoy!
