Proximal‐type epithelioid sarcoma of the vulva: Cytopathological diagnosis of a rare neoplasm

Proximal-type epithelioid sarcoma (PES) is a rare malignant mesenchymal tumour of unknown origin and histogenesis. The exact worldwide incidence is also not reported. Clinically, these tumours commonly present as vague masses involving the deeper soft tissues of proximal sites1 . PES has gained importance recently since it is recognized as a distinct entity with characteristic morphology, immunochemical findings and worse clinical outcomes.
