Plain-English summary
A 3-year-old female roller pigeon was brought in because she was limping on her left leg and unable to care for her hatchling. A large lump was found near her hip joint, and further examination revealed multiple tumors in her organs, including the pancreas and lungs. Unfortunately, the bird was humanely euthanized, and tests showed that the tumors were made up of cancerous T-cells. This case highlights the importance of monitoring for unusual lumps or changes in behavior in birds.

Abstract
A 3-yr-old adult female roller pigeon ( Columba livia ) used as part of a breeding pair for an ongoing research study presented with acute left limb lameness. Palpation of the left leg and region revealed a large lump near the coxofemoral joint. The bird was able to ambulate in the cage, but would not brood her hatchling. The bird was humanely euthanized and necropsy was performed. Grossly, multiple large white to pale tan nodules were noted in the pancreas, lung, rib cage, intestines, and unilaterally in the left kidney. Microscopic examination of the various organs revealed neoplastic proliferation of round cells consistent with lymphoblasts. Immunohistochemistry was performed with the use of antibodies to CD3, CD79a, CD20, and CD21 to phenotype the cells. The results indicated that the neoplastic infiltrating cells were predominantly of T-cell origin.
