Glad diet helped you too. There are so may types of eczema and it sounds like you husband has what my son does, Dysidrotic Eczema, DE which targets the hands and feet causes scaly, plaque like areaw which crack, bleed and peel. Unfortunately it is chronic and only treatments, like steroids which as we all know by know cause side effects like skin thinning and other issues with long term use are prescribed and of course good moisturizing and barrier ointments like Vaseline or Aquaphor (unless allergic to lanolin). My son has had digestive allergies since he was a baby, plus environmental allergies also. I would like my son to attempt an anti inflammation diet like I did with great success, perhaps it could help with DE, yet he is not willing to try that. Also I have not read where diet helps with this form. At least he is one of the lucky ones that doesn't itch from DE, but it does hurt when it cracks. The best site to identify all types of eczema, even rare ones, is dermnetnz.org. I have one common form of eczema, Allergic Contact Dermatitis, ACD, but my other two types are less common, one considered rare and it isn't even listed on US sites when you do an eczema search. The New Zealand site has the best collection of photos, your husband could search under DE and find others with his same symptoms. DE is considered a common form.
