Lesions of the gastrointestinal tract with massive tissue @entity1712 may present a difficult diagnostic problem. In a series of 250 @entity344 drawn from the files of St Bartholomew's and St Mark's Hospitals there were 28 cases of a @entity706 with distinctive histological features, characterized by a massive tissue @entity1712 . Two of these @entity5 were present in the stomach and 26 in the small intestine. Eight of the latter were associated with @entity66 . On low power examination a zoning phenomenon was regularly seen and fissuring @entity1066 , with perforation and @entity292 formation, was a common finding. The @entity5 cells were large and pleomorphic with irregular nuclear morphology and prominent nucleoli. Eosinophils were the predominant inflammatory cell associated with the @entity706 but plasma cells, epithelioid histiocytes and small lymphocytes were also present. Vascular changes were prominent. Involved lymph nodes showed gross expansion of the paracortex by @entity5 . Immunohistochemical studies showed that this @entity706 was probably of T-cell origin.
