Two Cases of Angiocentric T Cell Lymphoma Involving the Colon
Abstract
-
Angiocentric T cell lymphoma is characterized by angiocentric and angioinvasive infiltration. The vascular occlusion is usually associated with prominent ischemic necrosis of both tumor cells and normal tissue. Extranodal sites invariably include nose, palate, skin, lung and gastrointestinal tract. In intestinal angiocentric T cell lymphoma, patients present with acute abdominal pain, bloody stool o bowel perforation resulting from ischemic necrosis and have grave prognosis. We report two cases of angiocentric T cell lymphoma involving the colon. In the first case, the patient had the history o polymorphic reticulosis in left nasal cavity six years ago. In the second case, the patient complained of fever and diarrhea, and had splenomegaly. We assume that this is the first case of angiocentric T cell lymphoma involving the colon in Korea.
