I have had two ferrets with the apocrine cysts where the bubbles come from under the skin and are dark blue. The photo of this case is different, just skin colored. I also have a nine-year old boy that had a lump under the prepuce and had that removed. Vet thought it might have been a hemangioma. Oliver is still bopping around and happy without the lump or the big mast cell tumor that was removed from his neck at the same time. Carol J. Owens Ferret Friends,Inc. Tucson AZ [Posted in FML 6973]
