Two cases of monomorphic epitheliotropic intestinal T-cell lymphoma associated with coeliac disease. Scand J Gastroenterol. 2019 Jul 30;:1-4 Authors: Lenti MV, Biagi F, Lucioni M, Di Sabatino A, Paulli M, Corazza GR Abstract Monomorphic epitheliotropic intestinal T-cell lymphoma (MEITL) is an aggressive type of intestinal lymphoma which affects individuals without evidence of enteropathy. In this single-centre case series, we describe the first two cases of MEITL in Caucasian patients suffering from histologically-proven coeliac disease (CD). Original medical records were retrieved and anonymised. All biopsy and surgical MEITL specimens were reviewed by three haematopathologists. Two patients aged 63- and 55-year old at CD diagnosis, subsequently developed a MEITL. MEITL always involved the ileum and was multifocal. Both patients died from complications after surgery, including gastrointestinal bleeding, septic shock and multiorgan failure, with a mean survival since MEITL diagnosis of 15.5 ± 16.3 months. In one case, array-CGH revealed a large deletion on chromosome nine between 9p13.1 and 9p24.1, and a recurrent chromosome gain at 9q33-q34. Our cases indicate that a subset of MEITL may arise in Caucasian patients suffering from CD. The clinical, pathological and molecular features of these cases show a partial overlap with enteropathy-associated T-cell lymphoma. PMID: 31361171 [PubMed - as supplied by publisher]
