Squash cytology of tanycytic ependymoma: A report of two cases

Tanycytic ependymoma is a rare variant of ependymoma which has a predilection for the spinal cord. It is a WHO grade II tumour with favourable outcome. Although squash cytology of ependymoma is well described, there is sparse literature available on squash cytomorphology of tanycytic variant. Here we present two cases of squash cytology of tanycytic ependymoma. In the first case the diagnosis of tanycytic ependymoma was considered. However, in the second case a diagnosis of usual ependymoma was offered. Subsequently histopathology confirmed tanycytic nature in both the cases. In this article we discuss the squash cytological features of tanycytic ependymoma along with its differential diagnosis. Diagn. Cytopathol. 2017;45:270-273. © 2016 Wiley Periodicals, Inc.
