Marsh type 4 (atrophic) lesion has been made obsolete by the recent finding that refractory sprue, ulcerative jejunitis, and EITCL are all characterized by aberrant clonal T-cell expansions, as demonstrated by immunohistochemical and molecular techniques.
Primary refractory sprue can include many different pathologic conditions mimicking GSE, comprising collagenous sprue, ulcerative jejunitis, and EITCL.
