AbstractSpindle cell lesions of the salivary glands are rare and account for less than 3% of the salivary gland aspirates. A definitive classification of salivary gland neoplasms by fine needle aspiration is possible for the most common lesions but remains a challenge for the less common entities. We present a case of a 72‐year‐old male with a solitary fibrous tumour (SFT) of the submandibular gland mimicking a myoepithelial‐rich pleomorphic adenoma (PA). In this article, we discuss novel insights that help differentiate SFT from PA and other spindle cell lesions.
