Nodular fasciitis presenting as a parotid tumour after face lifting.

Nodular fasciitis, a benign, pseudosarcomatous proliferative lesion of the soft tissue, is frequently misinterpreted as a sarcoma, both clinically and microscopically. Lesions associated with the parotid gland have been very rarely reported. We report a case of nodular fasciitis mimicking a parotid tumour after a facelift. We performed histological and immunohistochemical study and CT scan for it is difficult to make a differential diagnosis. We confirmed the final diagnosis as intraparotid nodular fasciitis. Superficial parotidectomy was performed because of initial pathological misdiagnosis reported as a dermatofibroma. The subsequent diagnosis was confirmed to be nodular fasciitis on the basis of immunohistochemical study. There was no recurrence after follow-up to 18 months. Proper diagnosis of nodular fasciitis in the parotid region and early recognition of its benign nature are necessary to differentiate it from other various benign and malignant tumours of the parotid gland.
