A neoplasm of unknown origin in cervical and axillary lymph nodes was diagnosed as anemone cell tumor by ultrastructural examination. Three years after the initial diagnosis of anemone cell tumor, a high-grade transitional cell carcinoma of the bladder was discovered. The results of immunoperoxidase staining of the cervical lymph node, axillary lymph node, and bladder tumors for keratin, carcinoembryonic antigen, and human chorionic gonadotropin (HCG) strongly suggest that the anemone cell tumors in this case represent metastases of bladder carcinoma cells capable of producing HCG.
