This is a report of a case of Ki‐1–positive large‐cell anaplastic lymphoma in an 87‐year‐old man diagnosed on pleural and peritoneal fluids by cytomorphologic and immunohistochemical examination. Papanicolaou‐stained smears revealed many single, large neoplastic cells containing one or two nuclei with occasional multinucleated cells having a wreath‐like nuclear arrangement. The tumor cells expressed Ki‐1 antigen and epithelial membrane antigen. This is the first known report of Ki‐1 lymphoma diagnosed initially on cytologic examination of pleural and peritoneal fluids.
