Nodular fasciitis (NF) is a rare benign self-limiting lesion that is often mistaken for malignancy due to its progressive nature. Reported cases of nodular fasciitis in the parotid gland are uncommon, and its incidence is variable among different age groups. Histopathological and immunohistochemical studies are helpful in distinguishing these kinds of lesions. We report a case of a six-month-old baby with a two-month history of progressive rapid-growing mass in the left parotid region. Clinical examination showed some mild facial nerve weakness with no other significant findings locally or systemically. Fine-needle aspiration (FNA) was inconclusive, and surgical excision was the choice of treatment. On histological examination, the mass was confirmed to be nodular fasciitis, and on follow-up, the patient had no signs of recurrence. Nodular fasciitis can appear in young infants and, if confirmed histopathologically and immunohistochemically, should be treated conservatively.
