Abstract:
Nodular fasciitis (NF) is a benign tumor-like fibroblastic proliferation, and there have only been few reports about NF involving the parotid gland. Here, we report our experience of three cases of NF in the parotid gland, as well as our evaluation of the diagnostic tools for NF in the parotid gland, such as fine-needle aspiration cytology (FNAC), CT, and clinicopathologic investigations. In the three cases observed, all had growing masses in the parotid gland, and the lesions showed heterogeneous or peripheral rim enhancement on the contrast-enhanced CT, which could have been misdiagnosed as parotid malignancy. On FNAC, the cells had an elongated spindle shape and contained variable amounts of stromal matrix, which could have caused misinterpreted as pleomorphic adenoma. We observed dense cellularity and varying amounts of collagenous stroma, and immunohistochemical staining revealed positive reactivity to CD10, CD34, and smooth muscle actin. NF should be considered in the differential diagnosis of benign and malignant parotid tumors.
