Flow Cytometry Immunophenotyping Results:
Cytospin of the mesenteric lymph node FNA for flow cytometry shows a monotonous population of small lymphocytes, some with irregular nuclear borders, with interspersed larger lymphocytes with prominent nucleoli.

Population Reported: B-lymphocytes
Abnormal cells:  85 % of flow events

Mesenteric lymph node, fine needle aspirate, flow cytometry:
-CD10-positive B-cell lymphoma

Case Discussion

This case serves as a good companion and distinction to sclerosing mesenteritis, which can also present with a soft tissue mass in the mesentery. In this case, the mass is bulky and nodal, which is much more suggestive of lymphoma. A few enlarged retroperitoneal lymph nodes also favor this diagnosis. This was biopsied using a transabdominal approach with ultrasound.
