Symmetry? And Biopsy Location

Hi there

I am wondering if you must have a symmetrical rash to be DH. I only get rashes on one side or the other at one time, but they are suspicious for DH in all other respects.

Also wondering about the location of the biospy. Is it a lesion that should be sampled or an area of skin that is not in the rash that should be sampled? My GP took a lesion biopsy and it came back inconclusive. Went gluten free and haven't had any rashes since! (6 weeks now)

Any advice would be helpful.

Thanks

Everyone is different - I am sure someone out there has DH that is not symmetrical - but it typically is (mine is). The biopsy needs to be beside a lesion - not an actual lesion. My biopsy was taken right beside one on my elbow and came back positive.

Good luck - I hope you figure out what your issue is. Although if the gluten-free diet has helped you I would definitely stick with it! It really isn't that bad after you get used to it - I try to look at it like "it could be worse". :)

Can you explain why the biopsy should be beside the lesion and not the actual lesion itself? I've been fighting a rash for three years now and they biopsied the lesion and told me it was Grover's Disease. It used to not ich but it's starting to. It goes away if I take Acutane. I've been gluten free for 6 months, but I'm sure I not as strike as I should be and I know I'm becoming more intolerant to gluten.

I honestly do not know why - that is what I have read in my personal research. Someone else on here may know.

Anyone???

Hello Sandy O, I was diagnosed with Grover's Disease 2 years ago and it's gotten progressively worse. I do not fit the "mold" for Grover's. I'm a woman, have it on my scalp, arms, hands, trunk, and legs. All the cortissone creams on the planet haven't helped. I had to take Prednisone for an ecxema rash and the Grover's went away as did the ecxema, but Prednisone isn't recommended for Grover's. I haven't tried Accutane yet, but that's next on my list. The docs biopsy clear skin (non-lesion affected) so they can get an analysis of all potential skin diseases, not just the area that's affected. My father was allergic to gluten, so I'm going to try a gluten-free diet. I'm new on this forum, but will keep checking for new treatments for Grover's.

A positive biopsy consists of a specific microscopic appearance of granular deposits in the skin that are seen by a direct fluorescent antibody test for IgA-type antibody deposits. The deposits are widespread in the skin, and don't disappear until after months or even years on a gluten-free diet. Within the DH lesions, however, the pattern of granular deposits is disrupted or destroyed by the inflammation. Therefore, in order to see the classic pattern, it is necessary to biopsy the skin near a lesion, but not that skin directly involved in the blisters and rash.

Since the deposits in the skin are so widespread and long-lasting, doctors don't know why some areas are affected by lesions and others not, nor what triggers the attacks. Some correlations/theories I've seen include minor trauma to the skin, exposure to iodides, hormonal fluctuations, and, of course, increased ingestion of gluten.

Thanks for that excellent and concise explanation, Tricialee!

      Son's legs shaking

      Hi, My 7 year daughter has complained of this in the past, which I thought were part of her glutening symptom, but more recently I have come to figure out it's part of her histamine overload symptom. This one symptom was part of her broader profile, which included irritability, extreme hunger, confusion, post-nasal drip. You might want to look up "histamine...

      Son's legs shaking

      My 5yo was diagnosed with celiac last year by being tested after his sister was diagnosed. We are very strict on the gluten-free diet, but unsure what his reactions are as he was diagnosed without many symptoms other than low ferritin. He had a school party where his teacher made gluten-free gingerbread men. I almost said no because she made it in her...

      Not necessarily. The "Gluten Free" label means not more than 20ppm of gluten in the product which is often not enough for super sensitive celiacs. You would need to be looking for "Certified Gluten Free" (GFCO endorsed) which means no more than 10ppm of gluten. Having said that, "Gluten Free" doesn't mean that there will necessarily be more gluten than "Certified...

      Disaccharide deficient, confusing biopsy results, no blood test

      I think it is wise to seek a second opinion from a GI doc and to go on a gluten free diet in the meantime. The GI doc may look at all the evidence, including the biopsy report, and conclude you don't need anything else to reach a dx of celiac disease and so, there would be no need for a gluten challenge. But if the GI doc does want to do more testing, you...

This one symptom was part of her broader profile, which included irritability, extreme hunger, confusion, post-nasal drip. You might want to look up "histamine intolerance". I wish I had known of this at the time of her diagnosis, life would have been much easier.  I hope you are able to figure out.

We are very strict on the gluten-free diet, but unsure what his reactions are as he was diagnosed without many symptoms other than low ferritin.  He had a school party where his teacher made gluten-free gingerbread men. I almost said no because she made it in her kitchen but I thought it would be ok.  Next day and for a few after his behavior is awful. Hitting, rude, disrespectful. Mainly he kept saying his legs were shaking. Is this a gluten exposure symptom that anyone else gets? Also the bad behavior?

But if the GI doc does want to do more testing, you can worry about the gluten challenge at that time. But between now and the time of the appointment, if your symptoms improve on a gluten free diet, that is more evidence. Just keep in mind that if a gluten challenge is called for, the bare minimum challenge length is two weeks of the daily consumption of at least 10g of gluten, which is about the amount found in 4-6 slices of wheat bread. But, I would count on giving it four weeks to be sure.
