Nodular Fasciitis of the Parotid Gland

Nodular fasciitis (NF), very uncommon in the parotid gland, is a benign myofibroblastic proliferation that may be mistaken for other neoplastic proliferations.

NF of the parotid gland occurs in middle-aged patients who present with a mass (mean 2.2 cm) in the parotid gland of short duration (1.9 months).

FNA misinterpretation frequently leads to excision.

- fibrosarcoma ,
-  fibromatoses ,
