An Unusual Case of Enteropathy-associated T-cell Lymphoma Type 2 with Pulmonary Metastasis.

Herein, we present a very rare case of enteropathy-associated T-cell lymphoma (EATL) type 2 with pulmonary metastasis which was biopsy-proven. This is a very rare type of lymphoma, and no case reports or studies of enteropathy-associated T-cell lymphoma with pulmonary metastatic disease were found in the literature review. This 64-year-old male, who presented with an acute abdomen, was found to have a perforation. Subsequent pathology of the resected specimen showed neoplastic cells consistent with EATL type 2. Four months post-diagnosis, the patient developed shortness of breath. Positron emission tomography (PET) scan revealed multiple metabolically active pulmonary nodules. A biopsy of the nodules was consistent with metastatic EATL type 2 involving the lungs.
