Pathology Clinic: Nodular Fasciitis Involving the External Ear

Nodular fasciitis is a rare, benign lesion characterized by the pseudosarcomatous proliferation of fibroblasts and myofibroblasts. Accurate diagnosis presents a unique challenge for otolaryngologists, as nodular fasciitis frequently mimics malignancy clinically; however, it can be distinguished from malignancy by subtle findings on pathology. A diagnosis of nodular fasciitis should be considered for any irregular or rapidly growing lesion of the head and neck area, as accurate diagnosis is particularly important to avoid overtreatment in cosmetically sensitive regions.
