Clinical Information
- A primary peripheral t-cell lymphoma in the gastrointestinal tract, most often in the jejunum, associated with a history of celiac disease or other gastrointestinal diseases.
- An uncommon mature t-cell lymphoma of intraepithelial lymphocytes. It usually arises from the small intestine, most commonly the jejunum or ileum. Other less frequent primary anatomic sites include the duodenum, stomach, colon, or outside the gastrointestinal tract. It is seen with increased frequency in regions with a high prevalence of celiac disease. The prognosis is poor.
