Intestinal lymphangiectasia, a disease characterized by excessive intestinal protein loss, asymmetrical peripheral edema, ascites, immunologic deficiencies, lymphocytopenia, hypoalbuminemia, imparied lymphocyte transformation, gastrointestinal symptoms and retarded growth, is the result of abnormal, distorted and obstructed lymph channels, causing rupture of intestinal lacteals from back-flow of lymph, with leakage of nutrient-laden lymph into the lumen of the bowel. A case of congenital intestinal lymphagiectasia is described, with the additional problems of allergic asthma, rhinitis, eczema and lactase deficiency. This patient, an 11-year-old child, was greatly benefited by proper allergy management (elimination diet, hyposensitization) plus restriction of fats and supplementing the diet with medium-chain triglycerides (MCT).

Food intolerant symptoms can have various causes, including enzyme deficiencies (of lactase or aldehyde dehydrogenase) and pharmacological effects (e.g., caffeine, salicylates). The irritable bowel syndrome can also be associated with intolerance to specific foods in some cases, but the mechanism is unclear. Immunological causes are less common but may explain the small bowel mucosal changes associated with gluten enteropathy, as well as the childhood enteropathy provoked by cow's milk or, rarely, by other foods. Food allergy of the more immediate and classical type is associated with reactions both within and outside the gastrointestinal tract. Where these include urticaria, asthma and eczema, immunoglobulin E antibodies are often demonstrable by skin or radioallergosorbent tests, but pseudo-allergic reactions can produce a similar clinical picture. Diagnosis of food intolerance depends on withdrawing the food concerned and assessing the response to a blind challenge. Objective ways of detecting subclinical reactions are also useful, including the detection of a mediator response involving prostaglandins, histamine or serotonin.

The primary acquired lactase deficiency of the adult is known to cause various disturbances in the gastrointestinal tract while extraintestinal symptoms are unusual. Here we report on a histologically proven chronic eczema requiring corticosteroid treatment for several months. It was obviously induced by a concomitant lactose intolerance since the introduction of a lactose-free diet led to a complete disappearance of the eczema and allowed the discontinuation of the corticosteroid treatment. As far as we know, this is the first case report of an eczema caused by a lactose intolerance.
