[28 cases of malabsorption syndromes with villopathy].

A personal series of 28 cases of malabsorption with villopathy (22 Gee, 1 Whipple, 1 alpha-chain, 1 hypogammaglobulinaemia, 3 not yet diagnosed) is presented. The response to a gluten-free diet is the essential clue to diagnosis. Where sensitivity is not found, diagnosis becomes difficult and requires careful immunological, histopathological and parasitological investigation, which is not always conclusive. The main features of the series are indicated, along with the criteria employed in the diagnosis of some unusual forms.
