I was sharing some of the things I've found on the assorted malignancies I'm trying to find info on with a vet who is a distant friend and learned that some of the things about leiomyosarcoma (like it being possible in the adrenal capsule) and hemangiosarcoma in ferrets are not widely known, so I'll give those URLs for anyone who is curious: http://fhl.sonic-weasel.org/browse.php?msg=SG1845 http://fhl.sonic-weasel.org/browse.php?msg=YG7492 http://fhl.sonic-weasel.org/browse.php?msg=SG276 http://fhl.sonic-weasel.org/browse.php?msg=YG5395 http://fhl.sonic-weasel.org/browse.php?msg=SG1824 http://fhl.sonic-weasel.org/browse.php?msg=SG4256 http://fhl.sonic-weasel.org/browse.php?msg=SG2490 http://fhl.sonic-weasel.org/browse.php?msg=YG10013 http://fhl.sonic-weasel.org/browse.php?msg=YG9800 http://fhl.sonic-weasel.org/browse.php?msg=YG3132 There is some useful info at Dr. William's AFIP site at http://www.afip.org/ferrets/index.html which should help some for Chiclet if it is not an infection or lympho. Searching on "ferret and leiomyosarcoma" I found an oncology site at a vet school with info on causes of hypoglycemia in companion animals: http://www.vetmed.lsu.edu/oncology/hypoglyc.htm As of now I have read some of these things and others, and have more to read. So, whether or not these things help us, maybe they will help someone else now or during a future search. [Posted in FML issue 4175]
