Cytological diagnosis of nodular fasciitis can be challenging. The main features on cytological smears are bland, round to ovoid cells with fuzzy cytoplasmic processes in a background of focal myxoid change. The cytological features of two cases of nodular fasciitis are described here, along with the cytological differentials.
Chordoid glioma is an uncommon low‐grade glioma and is a CNS WHO grade 2 tumour in the current WHO 2021 classification. Predominantly it is seen in the third ventricle and in young adults. Although the histological features of chordoid glioma are well documented, there is sparse literature describing its cytological features. Here we describe the squash cytological features of a case of chordoid glioma along with summary of prior published cases. The smears tend to be quite cellular, the cells show mild pleomorphism, anisonucleosis, and absent mitotic activity. The background shows a distinctive bluish myxoid stroma. It can be mistaken for high grade glioma on squash cytology.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
