Pancreas Involvement of Extranodal Natural Killer/T-Cell Lymphoma, Nasal Type, Presenting as Acute Pancreatitis: A Case Report

Aggressive Biology of Extra-Nodal NK/T Cell Lymphoma: A Case Report

Extra-nodal NK/T cell lymphoma, nasal type (ENKTL) is a rare and aggressive non-Hodgkin lymphoma primarily seen in Asian and South American populations. Diagnosis involves methods like biopsy and molecular testing, with treatment typically combining systemic and radiation therapy. We present the rare case of a 62-year-old female who was diagnosed with localized ENKTL upon initial presentation of nasal congestion. She was started on radiation therapy and responded favorably at first, with decreased congestion and facial swelling. After five weeks of treatment, she developed significant dysphagia and anorexia, which was initially attributed to being a side effect of chemotherapy. After pausing radiation treatment, her condition worsened until she was hospitalized for obstructive jaundice. CT scans and biopsy confirmed metastasis of the cancer to her pancreas. Her condition rapidly declined until she was ultimately sent to hospice care.
