Hi All.

I just got back from the dermatologists office. Got the stitches removed from the two punch biopsy sites I had done a couple of weeks ago. The dermo says it did not show up as DH, but something called Lichen Simplex Chronicus. So I came home and Googled that condition. First, my "lesions" don't look anything like the photos I found of LSC; they look far more like DH photos I've seen. Second, LSC doesn't seem to appear bilaterally on the body; my lesions always have a counterpart (a mirror image on the other side of my body). Like clockwork - if I get a bump/sore on my right butt cheek, in a day or two I get one in almost the exact same place on the other side. Same with bumps on my legs and shoulders.

Is there a chance that the DH is being misdiagnosed as LSC? It's not like I WANT to have DH, but I'd like to be confident in the diagnosis. The dermo just suggested using Free and Clear laundry detergent (I already do) and keeping my skin moisturized with something like Vanicream (which I already do). 

This has been going on for two years for me, and I'm starting to get really frustrated.

I'd like to hear your thoughts...

Thanks!

It's possible it's being misdiagnosed. The big question is..... had you been continually eating gluten up until the time the biopsies were taken? Also, were you scratching the places where the biopsies were taken from prior to the biopsies?

 

I googled LSC & did not find anything that says it presents bilaterally. I did note that dh is listed as a differential dx of LSC but many other skin conditions are also.

Thank you for your response! Yes, I had been eating gluten - maybe just not enough every day. The two biopsies she took:  One was directly on a lesion, but I kept insisting that DH biopsies had to be peri-lesional. She just said, "not necessarily," and then took another one right next to the one on the lesion. This skin had been previously damaged by prior lesions so was not fully intact skin. I wanted her to take one from somewhere that had skin that had not been previously damaged.

I guess I just don't have confidence in how she did the biopsies. I think I'll wait awhile and then find another dermo and get a second opinion.

Thanks for the article. I am going to read it now.

A gluten cracker or slice of bread per day should be enough to keep the antibodies active. If she said "not necessarily" then she has it wrong. I agree, find another derm to do the biopsy correctly. Take someone with you for the next one so they can watch. Seems like terms like to take biopsies on your back or other places where you, the patient, can not see what they're doing. The pattern the lab is looking for it extremely easily destroyed either by scratching or by the rash itself destroying the pattern in that immediate area. This is why the only good biopsy is taken on clear skin adjacent to a fresh lesion. 

Be advised that the celiac serum panel is negative 60% of the time for those of us with dh so you can't count on the celiac blood tests necessarily.

Let us know what happens please and good luck.

Hi - when I first saw the dermatologist for my rash he quickly looked at and said I had LSC.  I never  heard of this so went home and googled it and was rather insulted to read that it is very common among those in nursing homes and psychiatric hospitals.  And like you the description and pictures did not match what I had. (next visit I was diagnosed with psoriasis/eczema, then scabies, then after a biopsy of the lesion itself :( some strange disorder that hits 1 in 10,000 people, finally GI doctor said DH),

I just did another search on LSC and see that it is caused by chronic itching so it is very possible you (as well as many others here) could have this simply because DH is one of the itchiest skin diseases there is.  So yes, you could have LSC but the underlying issue your doctor is missing is what is causing the itch that causes you to scratch so much that it is turning skin into a leathery mess.

I just found the below picture of LSC that looks very much like my dh looked but the other pictures on the same web site look nothing like this so maybe this person has dh as well as lsc.

      Conflicting results

      By Scott Adams · Posted

      It's possible he's in the early stages of celiac disease, and it has been caught before villi damage. The blood test results so far do indicate possible celiac disease, as well as his strong family history of celiac disease. If his symptoms get better on a gluten-free diet this would be another strong indication. Personally I think it's definitely better to proceed on the safe side and go gluten-free, rather than to risk severe villi damage and all that comes with it.

      Permanent Floating & Undigested Stools for a Year

      By Dora77 · Posted

      For some context: I have type 1 diabetes (T1D) (since 11 years) and celiac disease(since 4 years) For about a year now, I’ve been experiencing permanent floating and undigested stools. I’ve had a pancreas elastase test done. The first result was extremely low at 44, but a second test came back at 236. My doctor said that since one result is normal, it rules out pancreatic insufficiency because, according to them, elastase levels would always stay low if that were the issue. However, could the 236 have been a false result? My doctor also thinks I don’t have pancreatic insufficiency because I’m able to gain weight. I also get hgh injections as my bone age is younger than my real age, this also contributes to weight gain, so I dont know if weight gain can rule out malabsorption. But maybe if I had real malabsorption I wouldnt gain any weight even with hgh? For celiac, I’m on a gluten-free diet, but there might b small cross-contamination from things like pepper labeled as “may contain gluten.” or sausages which dont have gluten ingredient but say may contain. My doctor said that small amounts like this wouldn’t harm me and even mentioned that an occasional small exposure to gluten may not do much damage (which seems questionable since I thought even tiny amounts could be harmful). She also said that when Im older (Im m17) I could try eating small amounts of gluten and do antibody blood tests to see if I can tolerate small amounts or not. For reference, I’m asymptomatic when it comes to celiac, so I have no idea if I’ve been “glutened” or not. My first concerning celiac blood test was semi high IgA, then 3 months later we did a check up and my IgA was high so it was confirmed celiac. Since than I’ve had celiac antibody tests done yearly to see how my diet is going, and they’ve been negative, but I’ve heard those aren’t always reliable. I’ve never had a follow-up endoscopy to confirm healing. I also always kept eating „may contain gluten“ food. (I live in Germany so I dont know if „may contain gluten“ is as risky as in the usa but I suppose both are as risky) These stool issues started around the same time I was doing excessive heavy lifting at the gym. Could stress or lifting have triggered this, or is that less likely since the symptoms persist even after I stopped lifting? Occasionally, I’ll feel very mild stomach discomfort, but it’s rare and not severe. My doctor (also a dietist) said floating, undigested stools could still be “normal,” but that doesn’t seem realistic to me. Could this be impacting my vitamin or protein absorption? I also did a fructose intolerance breath test and had a high baseline of 20 ppm, but it never increased—only decreased over time. I fasted for 12 hours and didn’t eat fructose beforehand, but my stomach didn’t feel completely empty during the test. Could this mean the test was inaccurate? For lactose intolerance, I did the breath test but only fasted 10 hours and had eaten lactose prior because I wasn’t aware of the proper diet restrictions. My results were: 14, 12, 15, 25, 35, 40, 40 ppm—which would be considered positive. But given that I didn’t fast long enough or follow the right diet, could this result be unreliable? Has anyone else dealt with similar symptoms? What ended up being the cause for you? And sorry for the long text!

      Status Update...

      By TerryinCO · Posted

      The Docs' and NP haven't committed to Celiac determination yet but say go gluten-free diet because...  And I have with improved physical results - feeling better; overall functions better, and more energy.  Still 10 pounds down in weight but I still have BMI of ~23.  It's been just over a month now gluten-free diet.  I'm fortunate I get along with diary/milk well and most other foods. I wanted ask about this site's sponsor, gliadin X.  If this is legit, seems like a good product to keep on hand. Though it says it's only a safety for incidental gluten contact - not a substitue for gluten-free diet. What's your input on this? This may be sensitive subject since they're a sponsor. I've used resources here and other sites for information, gluten-free food/product lists. So thank you for all that support. That's it for now - Stay warm...  -2F this morning in Colorado!

      Increasing symptoms after going gluten free

      By cristiana · Posted

      I did suffer with gastric symptoms before diagnosis, but got all sorts of weird and wacky symptoms after going gluten free.   Things got much better once my antibodies fell to normal levels, but it took years (please don't panic, many people's go to normal levels relatively quickly when following a gluten-free diet). Causes of the symptoms you mention that I also experienced were iron supplements, a temporary dairy intolerance (this is common in coeliacs and should pass when your gut heals properly), and eating oats, as mentioned above.  Other symptoms I got were musculoskeletal pain after diagnosis, but again, once my coeliac blood tests were normal, I had no more pain. I did notice patterns emerging in foods that I reacted to and learned to steer clear of them, then gradually reintroduced them when my gut healed, such as soya, pure oats and dairy products.    You might like to keep a food diary.

      Conflicting results

      By Jy11 · Posted

      Well the conflicting results continue as the biopsy has come back negative. 😵‍💫 Waiting to discuss further but I really don’t know what to think now? Eight biopsy’s were taken from duodenum which surely should be sufficient if it was coeliac?
