The cytopathologic features of choroid plexus carcinoma in the cerebrospinal fluid of a 13-month-old male infant were reviewed and compared with those of other small-cellk malignant neoplasms of childhood and young adulthood involving the central nervous system. The cytologic features of the choroid plexus carcinoma (tight spatial clusters and isolated anaplastic cells with striking nuclear lobulation) were distinct from those of lymphoma, leukemia, neuroblastoma, ependymoma, and pineal germinoma. However, the cells had a striking resemblance to those of anaplastic ependymoma and metastatic adenocarcinoma.
