A 79‐yr‐old woman presented with a 5‐yr history of swelling of the left cheek. The fine‐needle aspiration (FNA) smear showed a spindle‐cell neoplasm with capillaries and benign endothelial cells. The spindle cells possessed pleomorphic, hyperchromatic elongated nuclei and a moderate amount of ill‐defined cytoplasm. They also showed papillary arcades surrounded and encased by relatively small ovoid to short spindle cells. Subsequent surgical excision confirmed the presence of malignant hemangiopericytoma (HP). Immunohistochemical studies on the histologic section using vimentin were strongly positive, consistent with HP. To the best of our knowledge, this is the second published report of FNA cellular features of malignant HP of the salivary gland. Besides delineating the FNA cellular features of HP of the salivary gland, the present case illustrates the value of using immunohistochemical approaches. Diagn.
