Jaundice caused by primary common bile duct lymphoma of a cat
A 10-year-old American Shorthair cat presented with anorexia and jaundice, and echogenic evaluation revealed diffuse thickening of the common bile duct (CBD) wall. An exploratory laparotomy was conducted, the lesion was evaluated as difficult to remove, and the cat was euthanized and autopsied. Histologically, round neoplastic cells proliferated in the mucosa of the CBD and infiltrated the hepatic lobe, pancreas, and duodenum. Immunohistochemistry revealed that the neoplastic cells were positive for cytoplasmic-CD3 and granzyme B, and TCR-gamma clonal rearrangement was detected. Based on these findings, the neoplasia was diagnosed as a primary CBD lymphoma originating from cytotoxic T or natural killer cells. To the best of our knowledge, this is the first reported case of feline primary CBD lymphoma. Although rare, lymphoma of the CBD should be considered in cats with jaundice and thickening of the CBD.
