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.

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!

When I first got the calendar from Mercedes Medical in the mail as a promotion, not even looking at it, I tacked it up on the wall.  The first month I saw was March but being so busy, I didn’t even have time to look at the picture.  Then I turned the picture to April and saw the above picture.  Does anyone (beside me) recognize it?  I mean, aside from what stain or tissue it is, but more importantly to me, where it comes from.

I’ll give you a hint, it’s originates from this site.
