A 48-year-old woman came to our attention because of a vague abdominal discomfort. An oesophagogastroduodenoscopy performed to exclude CD turned out to be negative, as did serological testing and HLA DQ2 and DQ8 genotyping. Ten days later, the patient underwent a surgical resection of the jejunum because of intestinal perforation. After diagnosis, staging procedures (bone marrow biopsy, and positron emission tomography and CT scans) were negative for further sites of involvement, and the patient was treated with intensive chemotherapy and autologous stem cell transplantation. Ten months after the diagnosis, the patient was alive, with a poor performance status, but without active disease.
Macroscopically, the surgical specimen consisted of a tract of jejunum with …
