NCI Definition: A clonal T-cell lymphoproliferative disorder that can involve the mucosa in all sites of the gastrointestinal tract, but is most common in the small intestine and colon. The lymphoid cells infiltrate the lamina propria but usually do not show invasion of the epithelium. The clinical course is indolent, but most patients do not respond to conventional chemotherapy. A subset of cases progress to a higher-grade T-cell lymphoma with spread beyond the gastrointestinal tract. (WHO 2017) [1]
