Question

IMG_0903
Hi, My 6yr old Dwarf Lop currently has a skin problem that has us all at a loss. It started in April this year with flaky skin.  A scraping was done by my vet and 1 mite found so was treated with Xeno 450.  Seemed ok but in June, scabs had started to appear on his back; was dosed again with Xeno 450 - made no difference. July they checked to see if it was bacterial or a fungal infection both results came back negative.  The scabs are really compacted and white. The next step was to pick the scabs off and bathe with diluted iodine.  When the scabs come off the skin underneath is always a nice healthy pink colour and occasionally there is some bleeding but no red soreness. They do not bother him and he is fit and well otherwise.  For a short time things looked better.  When the scabs came off the skin healed and new hair growth was seen. The current situation is the scabs are getting worse and the vet thinks eventually it will spread everywhere. He has 4 scabs; one on his shoulder, 2 on the back and one near his back leg, they have never been on his head etc.  New hair growth is growing through the scabs and to me the scabs  seem thicker. Today he is actually at the vets having a piece of skin removed to send to a pathologist to determine what cells are around the infected area.  Have you come across something like this before?  Can you shed any light at all?  None of my other rabbits have contracted it. I have attached a picture of a scab - I hope you can see it clearly.

Thank You
Catherine - starting to feel a little desperate.

Answer
Dear Catherine,

The vet is doing absolutely the best thing by taking a biopsy and sending it to a good lab for histopathology.  The only thing I can imagine is that this could be a manifestation of sebaceous adenitis, which is believed to be an auto-immune disorder.  It can be controlled to some degree with corticosteroids, but these are not great for long-term use, especially in rabbits.

I hope the pathologist will be able to shed light on this mysterious condition.  In the meantime, ask about Stronghold (selamectin) instead of Xeno 450 (ivermectin), as selamectin is longer-acting and might be able to better control this if it's of parasitic origin.

If you have time to let me know the results, I would be curious.  I hope he will be diagnosed and on the mend soon.

Good luck,

Dana
