label_lc: multifocal lymphomatous polyposis
description: A clinico-pathological entity reflecting the multiple polyps throughout the gastrointestinal tract created as a result of involvement by a non-Hodgkin lymphoma. Typically, mantle cell lymphomas involving the gastrointestinal tract give rise to multifocal lymphomatous polyposis. Importantly, other histologic subtypes of non-Hodgkin lymphoma can also produce this clinico-pathological entity.  (WHO, 2000)
