Abstract

Enteropathy-associated T-cell lymphoma is a rare type of peripheral T-cell lymphoma that characteristically involves the jejunum or ileum. Awareness of the histologic and immunophenotypic features of this subtype of lymphoma is important for accurate subclassification. Enteropathy-associated T-cell lymphoma has 2 forms, classic and type II, with different clinical and pathologic features. The 2 types will be described and discussed, with an emphasis on how to differentiate these entities in routine practice.
