The histomorphology of nodular fasciitis (NF), a benign proliferation of myofibroblasts, is well described in the surgical pathology literature. The cytomorphology, however, has been reported infrequently. Cytologic interpretation of this pseudosarcomatous lesion is subject to the same pitfalls so frequently reported for histologic material. NF arises most commonly in the extremities or trunk; occurrence in the parotid gland is relatively uncommon. We describe a case of NF arising in association with the parotid gland; review the clinical, cytologic, histologic and immunohistochemical features of NF; and offer a differential diagnosis, based on cytologic features, of other benign and malignant lesions likely to be encountered at this location.
结节性筋膜炎（NF）是一种肌成纤维细胞的良性增生，其组织形态学在外科病理学文献中有详尽描述。然而，细胞形态学方面的报道却很少。对这种假肉瘤性病变的细胞学解释容易陷入与组织学材料中经常报道的相同陷阱。NF最常发生于四肢或躯干；发生于腮腺相对少见。我们描述一例发生于腮腺的NF病例；回顾NF的临床、细胞学、组织学和免疫组化特征；并基于细胞学特征对该部位可能遇到的其他良性和恶性病变进行鉴别诊断。
