Primary follicular lymphoma of the pancreas: A rare tumour mimicking pancreatic carcinoma.

We report a case of a 75-year-old man who presented with symptoms of obstructive jaundice. Ultrasonography and computed tomography (CT) showed an ill-defined lobulated soft tissue lesion at the head/uncinate process of the pancreas measuring 4.5 x 4.9 x 5.8 cm. The patient underwent pancreaticoduodenectomy for suspected pancreatic head/uncinate process carcinoma. Histopathology and immunohistochemical assessment of the pancreatic lesion established the diagnosis of a low-grade follicular lymphoma. DISCUSSION: Clinical and imaging features of primary pancreatic lymphoma may often overlap with pancreatic carcinoma. There is a value of obtaining preoperative tissue diagnosis such as tissue biopsy and fine needle aspiration (FNA) cytology with or without flow cytometry to make an accurate diagnosis of non-Hodgkin lymphoma and alleviate the need of more radical surgery in pancreatic lymphoma.
