Russell P. Gollard, MD

A 53-year-old man, who had initially presented with an upper respiratory tract infection, was found to have a stage IV follicular low-grade lymphoma with malignant cells that were positive for CD19, CD20, CD10, surface kappa, and CD45 and negative for CD5. A grade 1 tumor (follicular center cell lymphoma/follicular small cleaved) was suspected. Enlarged lymph nodes (2.5 to 4.0 cm) were found in the mediastinum, azygoesophageal recess, and periaortic region as well as in the porta hepatis, peripancreatic, mesenteric, and celiac regions.
