Primary lymphoma of the head of the pancreas.

Primary and isolated lymphoma of the head of pancreas with secondary involvement of the lungs and obstructive jaundice, in a 31-year-old postpartum woman, is described. The histological diagnosis was diffuse histiocytic lymphoma. Chemotherapeutic treatment resulted in complete remission of the tumor. During therapy a pseudocyst of the pancreas developed and a gastrocystostomy was performed. This is the second reported case of primary pancreatic lymphoma in the English medical literature.
