Complexity of the differential diagnosis of primary T-cell lymphoma and Crohn’s disease by the example of a clinical case

Abstract

The article presents a clinical case of a rare disease — primary intestinal T-cell lymphoma (PITL). A distinctive feature of PITL is the absence of typical clinical, laboratory and instrumental manifestations. This requires performing differential diagnosis with other diseases such as Crohn’s disease, chronic mesenteric ischemia and infections. The diagnostic standard of PITL is morphological verification. In this case, the diagnosis of PITL, NOS was made during the immunohistochemistry of the biopsy of the resected intestine.
