Dr. Oglesby, DVM
I just purchased a 2 year old from a friend of mine the last weekend in May. Two weeks before I was to bring him home she worked with him on saddling, only working him in the round pen and sitting on him. One week before I was to come she said he had some bumps on his side that appeared almost overnight and thought it was an allergic reaction from bug bites. The bumps are still there, except I washed him in a medicated shampoo the last two weeks and a small part of them are gone.
I contacted Nena from Cornell University after reading the article on HERDA and she was concerned because of his breed line. She said from hearing his line he could have a 50% chance on the Sire side and 25% on the Dam side, leaving him with a 1 in 4 chance of having it.
I sent her pictures of the bumps and she is going to let me know what she thinks next week.
I am not sure where to go from here...do I stop saddle breaking until I hear and even if I do hear, since there is no way to really tell unless it is a severe case, do I just wait to move on with him or do you think a biopsy would help???
I have pictures that I will try to attach a picture of the bumps - I have not had my vet look at them yet because I really didn't think I had much to worry about until I talked to Nena yesterday. I am praying that these bumps are from something else!!!
P.S. I did do the skin test and could not find any areas I could pick up

Hello Pam,
Before the evaluation of the pedigree I would have said you have little to worry about even looking at the picture. The picture is not specific enough but both hives and early crusts from a disease like dermatophillus could look like this.
The first step is to have them evaluated by your vet. Besides their appearance the way they feel and shaving the hair off of them will help evalating them. I would tell him your concerns so he can study up on what to look for. If after the exam it is still unknown a biopsy would be a logical next step.

Dr. Oglesby,
I thought I would give you the update to the problem above. My vet worked with Nena from Cornell University on the above problem. My vet shaved the area and injected him with steroids and the bumps with steroids - I thought they went down a little bit but they seemed to have come back. My vet also took a fluid sample but did not find there to be a fungus type of problem. The horse has no other symptoms of Herda but he does have a 1 in 4 chance, according to Nena.
He is at a trainers now, just starting under saddle, and I have noticed the patch of bumps is getting longer and a few of them seem to have merged together. We thought there was crusting on a couple of them but we can't be sure. I decided to go ahead with training since the bumps don't seem to bother him, he has another month to go at the trainers.
I am wondering if I should get a biopsy or is there a vet that specializes in skin diseases? Also, would a hair analysis help to check his diet?
Thanks!
Pam

Hello Pamela,
After my optimistic appraisal of July 17th, their continued presence is not a good sign. I presume the bumps are fluid filled, and this was where the fluid came from? Was it easily aspirated and what were the findings, exactly?
We have a brand new scientific report that reviews the clinical presentation of 50 suspected cases of HERDA and addresses the findings on biopsy (histopathology).

Dr. Oglesby,
I am not sure what you mean by findings but my vet tried all the things that Nena told her to try with feel and touch but my vet did not feel what HERDA is suppose to feel like. They feel like a firm bump under the skin. Her fluid sample was to see if it was fungus related but that was negative. It was very difficult she said to get fluid. Nena said we more or less had to wait and see.
Where can I see pictures or documentation of the 50 suspected cases?
One thing Nena said was that there could be degrees of the disease and all I might see is the bumps if he does have it?? So should I go ahead with the biopsy? Nena said she could instruct my vet on how they need the biopsy done, but once again, will all that do any good???

Dr. Oglesby,
I went ahead and called Nena, she said she was just wondering about us and was going to call my vet. I mentioned to her that they were spreading - she did say that was not good. She has asked me to take more pictures to send to her. She also mentioned that if this was HERDA, there are some great cutting horses still competing that have mild forms and they work around it. Nena also said a biopsy probably won't do any good at this point - only a few biopsies have been able to reveal any thing that barely helps a diagnostic.
As soon as I go see him in about a week, I will post the photos I send her for others who may have the same thing.

Dr. Oglesby--I joined this thread because we have a 2 year old filly with suspected HERDA, and I'm wondering where I can find the research report you mention in your message to Pamela Greisinger of Sept 15, 2005. Can you point me in that direction, please?

Hello Elizabeth,
You will find it in the article where we have tried to group together all the hereditable skin disorders at, Equine Diseases » Skin Diseases » Hair and Coat Problems / Itching / Irritated Skin » Epitheliogenesis Imperfecta (EI) & Hyperelastosis Cutis.
