title: Transitional-cell carcinoma metastatic to cerebrospinal fluid: presentation of two cases.
abstract: We present 11 specimens from 2 patients with transitional cell carcinoma metastatic to the cerebrospinal fluid. This is a rare occurrence documented in one previous report in which 5 patients had 28 specimens reviewed (Ehya et al., Acta Cytol 1981;25:599-610). Cytologic features that most likely indicate a bladder origin are the cytoplasmic tails and cytoplasmic pseudopod formation.
