B-Cell Lymphoma Presenting as a Pancreatic Mass.

Non-Hodgkin lymphoma (NHL) has many subtypes, with diffuse large B-cell lymphoma being the most common subtype. Typical symptoms of NHL include fever, weight loss, night sweats, and lymphadenopathy. Treatment depends on the subtype of NHL. Our case presents the clinical course of a patient who presented with obstructive jaundice and pancreatitis rather than typical symptoms of NHL. Workup included abdominal imaging showing a pancreatic mass and biopsy ultimately revealed high-grade B-cell lymphoma. This case presents a rare diagnosis of likely primary pancreatic lymphoma.
